Basicly every now and then our car decides it's not going to start and it just cranks n cranks n cranks and we always end up having to clutch start it. And when the car does start it will blow alot of fuel smoke, coughs and splutters, fuel smoke dies off after about 5 seconds.

Thing is this happens if its wet, dry, if the engine is cold, hot, if it's been driven normally, or if u give it a little boot, small trips, long trips, its ultra random.

We have so far tried a couple of things. We unplugged the injectors and the car turned over and ran untill it ran out of fuel. We had our injectors checked and cleaned about 4 months ago, flowed fine, no drips.

We got a new battery so it's not that...and we have it serviced reguarly.

Basicly wondering if anyone has any ideas on what could be causing this problem?

hi there socko you will need to check the fuel pressure regulator to see if diapham has a hole in it which causes the fuel pressure in the rail to bleed back into the mainifold and flood the engine when you try to start it . the easiest way to do this is to pull off the vacuum line that goes to the pressure reg and see if it has fuel in it Try that first and let me know thanks mate

Ok that's worth checking n I will get Adrian to check that when he gets home from work. Because it is getting to much fuel when it's doing it...But wouldn't that cause it to do it all the time? The car only does it randomly...Altho it is starting to do it more often...

My rb25 does exactly the same thing but all the time. Its rare that it starts straight away. Receipts i got with the car show like 4 new batteries so thats not it. Always starts eventually but cranks for like a good 10secs. Checked the FPR hose and is dry but that was bout 15mins after turning off the car. Should i check when turning on the car or will it make no difference? Any help appreciated

We went to a guy yesterday and he plugged our car up to the computer and it ended up being the water temp sensor.

Basicly the water temp sensor was sending the cars computer the wrong singal which lead to it thinking it was cold all the time. So off course it kept putting more fuel into the engine than it needed and it was flooding it's self. Which explains the problem starting it and the problem while driving it.

So it's all good now :)

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
