Yeah mate same boat here, i have a power fc though and i think its something do do with fuel/ignition timing vs intake temps on startup?

never sure but last 2 days its been hot and my car has taken a couple of attempts to start.....same in very cold-start conditions.

:D ignition module or coil packs or something else???

any help appreciated

What ECU do you have?

Go into 'settings' then 'cranking' and have a look at the 50deg and 80 deg settings.

Change the 80deg to 9.0 and the 50deg to 10.0 and see if it starts easy for you.

oh mad, ill take a look at my controller and report back. Thanks man

Apexi power fc, nah mine wont start at all when its hot.

Bought an fitted a new ignition module wasn't that. it was a waste of $900

still have to push start it when its hot :D very embarrising in the middle of town.

ordered new set of splitfires should arrive tuesday

*oh sorry i meant when the engines hot not the air temp.

yeah i agree with stevel, sounds like its the starter motor, make sure your alternator is also working though and your battery is ok. should be 13.6ish-14.5ish volts when the car is running(at the battery). and if your battery is over 3 years old id almost consider it f'ed.

Im very confident its the starter motor. I had the same problem 2 years ago when i had a FORD PROBE. Same deal, wouldnt start on odd occasions. Changed the starter my self (easy to do) and the problemm was fixed. Give it a go i say

wont be coil packs either as others have said... push starts = starter motor.

my mate had this issue, check this thread out

"yea i had this issue on my rb it was voltage drop ( once the car gets hot the power to the starter is actually less cause the voltage has more resistance in the wire)"

:) No not the starter motor, motor turns over quite easily for the first six attempts than starts to slow down as the battery gets flatter. just wont fire up.

the reason i think it could be the coils is it runs fairly rough on idle after driving/thrashing it for a fair while, seems to miss a bit down low.

only started doing it since i had a lot of work done to it boost turned up to 20 psi ect. the mechanic said the coils mightn't keep handling it.

an that was his guess of the problem.

did you try changing the cranking values as dan said - I have had this exact problem you are describing put up with it for months till I called into ERD last weekend and he has the car hot starting in a matter of minutes...

I have the same problem starting mine when its hot. Not the starter motor as the engine turns over fine. If i don't get it started on the first attempt, it wont start at all....just keeps turning over...

However (don't ask me how i figured it out), if I disconnect the first injector and try again, she will start, then I plug in the injector power again :D:(

I reckon it is over fuelling or something because I can smell the fuel in the engine bay, and black smoke comes out of the exhaust after it starts.

Any other ideas?

BTW im running a NISTUNE remap. Would take it back to the tuners but some 'champ' rear ended me so I have been following that up....

Reason is Starter motor, I have it right now.

Unfortunately the starter is fairly expensive. Either the heat shield has been removed in perhaps a clutch install or the starter is shitted itself.

it will eventually die, until then it may start with abit more gas and longer ignition.

secondly its not the tune... at all.

douse sounds like a fueling issue with ur car.

to fix replace starter, install a heat shield. it stops working because the starter absorbs heat and it requires more power to fire. you may want to try run a bigger ground first, check the power at the starter first warm vrs cold. or perhaps warm car up let it sit for 20-30 mins when it absorbs most heat and then hook up a jump start see if it fires then this may mean the battery is rooted.

What ECU do you have?

Go into 'settings' then 'cranking' and have a look at the 50deg and 80 deg settings.

Change the 80deg to 9.0 and the 50deg to 10.0 and see if it starts easy for you.

My 33 has a PFC. When it's really cold it cranks and starts but I have to keep revs up above 1000RPM for a few seconds with the throttle, otherwise it sort of bounces revs and stalls.

Is this a cure or any other ideas???

Cheers,

Ben

Sounds like a faulty temp sender. The ECU thinks the engine is still cold, so it adds lots of fuel for a "cold start"

will this change the tune at all??

dont know much about tuning at all, just know it was dyno tuned for hours an was told that, down low on cruise he has kept it as lean as possible an at 20 psi its running rich but on its limit of knocking. an a slight change to the tune an the engine's buggered.

still waiting on new coils should arrive any day they've bn sent. other wise i'll have to plan a trip back to brissy an let mark figure it out.

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
