Car Wont Start After Rebuild...

[Abo Bob]

Hey guys. Any suggestions?

I put the engine in the car and instead of putting the earth wire from the body of the car to the engine like I should have I connected the wire from the body to the positive terminal of the battery. Of course the body was also connected to the negative terminal of the battery at the same time and so the battery started to boil.

Anyway it's all wired up right now (well that part for sure) and now even with a new battery it wont start. The fuel pump primes, the lights on the dash go on but when I turn the key to start there is no sound from the starter motor.

I have tested the starter motor with some alternative wiring and it works fine.

What do you think I've done?

checked the fuse box?

[Beer Baron]

check the fuse box as suggested. there is also the possibility that you have damged the ecu. were there any funny smells inside the cabin?

[Abo Bob]

I was expecting electrical burning type smells but didn't notice any.

I just did an ECU test and got 55 which is no errors so the ECU is fine.

I've checked the fuses as far as I can although some of those big ones I'm not sure how you tell. Perhaps a multi meter for continuity?

I did swap a few of them around and it made no difference.

When I connect the battery there is a spark indicating something drawing current straight away. Dunno if it's the alarm or something not wired up right.

I just can't see what I've wired wrong...

Any auto electricians in Sydney wanna come over and fix it for money

that you've done?

Only thing I can thnk of is the main cable from the battery to the starter (same size as earth cable) isn't connected.

Start solenoid wire (R32 - thin blue) connected to the start motor/solenoid?

Hey Abo Bob,

I am wondering whether your neutral safety swich is working and wired up as it should be. (Couple of assumptions here that you still have the auto (and that they use one)).

El Bee wins a pat on the back although I figured it out by myself. The plug for the neutral safety switch was only half clicked in. The starter motor now works fine.

However...

The bloody thing still wont start.

I have taken the cam gear cover off and checked that the dots line up with the marks on the plate behind them and it's all fine. I have moved the CAS mm by mm around it's entire range and still it wont start.

I got a few good backfires but now it wont even do that.

Now what?

did you flush ALL the fuel out of the tank and lines? as ANY old fuel will contaminate the new brew. This same thing happened with "twoogle"

[Swiper the Fox]

plugs are probably gone now too....go a full flush, fresh batch of fuel and new plugs and i think you may have a goer.

good luck Adam

I don't see why old fuel would mean the car won't start?

I'd be thinking to check if any fuel in the lines to the engine.. When I run out of petrol usually takes atleast 10l+ and a lot of priming the pump and hitting the accel to get petrol back into the engine.

edit: also helps if it aint on a hill with the incline tipping the car towards the rear of the car.

stale fuel does not combust.....thats why the car wont start....or that is why ours wouldnt. As i said we flushed the tank after we emptied it, (dont forget the lines fuel rail and filter) with fresh fuel and like magic.....the car started.

You may have also burnt out your earth lead....did it not let out a large spark when you connected it to the pos+ terminal?

I see.. that must have been a long time no? I would have thought the few months the car's been off the road it would still be ok? I've had another car sitting for longer than Adam has had his off the road and it was fine.

[Abo Bob]

There wasn't much of a spark when I had my wiring mixup.

I was using the old fuel. New fuel now in. It thought about starting. I'll get some new plugs tomorrow.

Anyone know what heat range etc I need?

cc - sounds like you run out of petrol a lot... I definitely had fuel in the lines.

[dacow]

hope you have better luck tomorrow mr bob!

[Craved]

heat range of 6 or 7 adam on the plugs

Must have been something else coincidental. I had mine off the road for about 5 months, with a realatuvely empty tank, and managed to get it started and running OK. Just needed a good battery to fire everything.

No it WAS the fuel...no coincidence....

Adam...run 7's if your running more than standard boost.

I may have fouled the plugs now with all the cranking.

maybe cas has been broken somehow.
