So this morning I went to drive to work and my car just gave up. I unplug the igniter and the air flow meter when ever I go away for a weekend.

So I plugged them back in and then started the car. It idled for a little bit and as soon as I put it in gear and went to take off it stalled.

Now it won't even turn over.

Any ideas?

I checked both the igniter and the airflow meter plugs. It's my daily so I'm pretty screwed without it

Left your lights on? :P

I had a bit of a scare this morning. My electric key wouldn't unlock the door so I had to do it the old fashion way which released the alarm. Had no idea how to turn it off without the key working but then it just worked :D Small scares.

Could still be a flat battery braaaaaaa. If it literally doesn't turn over at all, then either your starter motor is f**ked, the battery is dead, or a fuse/solenoid has shit itself somewhere. It's almost certainly nothing to do with the ignitor or AFM, unless it DOES turn over but just doesn't fire.

When you put the key in the ignition and turn it to start the car, describe EXACTLY EVERYTHING that happens - does it make a rattle/clicking sound? Does the engine turn over but not fire? Does it prime the fuel system?

No good man. Let's hope it's nothig major ! Summon Rob # He always seems to give great guidance / food for thought.

edit: I also had this similar issue couple of weeks ago. NRMA came out for 30 seconds to plug my alarm plug back on the battery hahaha I felt like an idiot.

Nah it has power you can hear it trying to turn over but it just doesn't grab. Lights 100% weren't on.

are you saying you can hear the starter spinning but not turning over the motor?

if this is the case turn it off then flick it straigh back on. sometimes will cause the pinion to push out as and grab the flywheel

Okay so when I turn the key I can hear it making the normal starting rev noise trying to start the engine.

But it just doesn't grab and start up. I have had a flat battery before and noticed it just makes a slight noise when that happens.

This is different. It's very similar to if you ran your car to empty and then tried to start it.

I do have a full tank of fuel though

if you're getting a clicking noise, kinda hollow, then your starter is gone (happened to my mate) if all electronics work fine then your battery is also fine...next up would be spark plugs? no reason for them to randomly die but who knows, could happen? maybe put up a sound clip of you trying to start it? if you said it sounds like trying to start a car on empty tank then yeah, might be sparkies cos that's what mine sounded like when i needed to change them too.

though one more thing - check the loom connections to the battery, all terminals are secure and not wiggling - then grab the looms and give them a wiggle, a few times, try and start the car, and wiggle again. might be a loose connection somewhere.

Stop trying to start it and take it to a shop. You will risk detonation if it starts to flood the engine.

Hahaha I was in a huge rush this morning so my mind was all over the place. It's kind of hard to describe a noise. Ill check the plugs again when I get home and also pull out the spark plugs and check them.

I can hear the fuel pump prime and then stop. But I'll pull a fuel line off and check that as well.

Anything else I should be checking as well?

i don't mean to sound like a dickhead (especially towards such a little sweetie as yourself, Dan), but you're still failing to answer the damned question lol :P

The engine "turning over" has nothing to do with it firing up - when you turn the key to the start position, does the starter motor turn the crankshaft successfully? I repeat - this has nothing to do with the engine firing, simply whether or not the starter is doing its job. If the battery is flat or if the starter motor has failed, the answer you'll be giving me here is "no".

When the key is turned to the final stage in the ignition (where it is supposed to start the engine), a few things should be happening - power is given to a small solenoid on the starter motor which causes the pinion gear on the starter motor's shaft to move out and engage with the flywheel. It then also gives power to the starter motor itself, causing it to turn the flywheel. If your battery has sufficient charge, these functions will still go ahead - the engine will "turn over".

Should the engine fail to fire as it should (and subsequently begin to run), the issue at hand will lie somewhere in the ignition system or fuel system (I'm not sure what will happen if the AFM is unplugged - will it not fire at all or run in some sort of limp mode?). Given you unplugged the AFM and ignitor, this is most likely where the fault lies - potential bad connection in the plugs (possibly from moisture as you suggested), or potential failure of one of these parts (possibly just bad luck when you plugged them back in).

While there are many many many things that can stop an engine from starting correctly, you should always start the investigation with things that have recently been fiddled with, especially if the car was running fine before you fiddled with them ;)

He means it wont fire.

So, basics guys, its spark or fuel.

you mean fluid lock? bust the head off?

Haha no pre-det. You would burn out your starter motor/flat battery before nearing hydrolock.

Dan by some electrical cleaner clean ignitor/afm my as well clean tb and cas sensor at the same time will get rid of moisture Charge the battery up give her another crack.

If its still no go it has to be spark or timing since you can here the pump prime.

Hey Troy,

So I don't know the difference in the noise between those two steps in the start up you are talking about. Ill have to wait until I get home this afternoon. Might try get a video of it and send it to you.

I'll post up here this afternoon around 6:30 when I get home and start getting my hands dirty. Hopefully I can sort it out before work tomorrow

As per our sexting just now, you finally answered my question :P

Check AFM and ignitor plugs first - Do what Pat suggested and get some electrical contact cleaner to spray on the plugs and clean them out. Hopefully it's just moisture.

If that doesn't fix anything, check fuses. If the fuses look fine, then consider that by some unlucky chance either your AFM or ignitor shat itself at some stage through this adventure lol

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.  
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
