WONT START

Yes turns over fine but no sign of firing? :?

Check you're getting fuel at the engine and that you're getting a good strong spark. I expect you won't be getting one of them, so let us know which one.

Can you hear the pump priming the system when you turn the igniton on?

If you're getting neither, check the ecu relay hasn't died.
If you have no spark, check the plugs/leads/dizzy/cap/rotor arm/ cas/ power amp/coil ect
If you have no fuel check your pump/filter/injectors/dropping resistor/pressure regulator etc

wont start

Cheers for that advice! I took pipes off fuel filter and filter was full and pipes had fuel in them.There is a slight solenoid type click when ignition is turned on.The car quite recently had a new combined alarm/immob fitted at nissan could that possibly play up? Having said that tested for power at blocks connecting to top of tank and its reaching there okay.Swear car is possesed! everything great until i threaten to sell.Find someone who wants to buy then it sulks!!!! :evil:

it cant be the alarm playing up as if it was the immobiliser kicking in then it wouldnt allow it to turn.

i think it sounds like sparks, or something to do with the ignition lot.

ul have to run over everything

 

[Fast Guy]

It depends how the immobiliser is wired in. If it's 2 channels :- starter and ignition, then it probably won't be that. But if it's not wired into the starter motor, it could be that.

SORTED

My mate and ex owner of my car came round with his box of gizmos.He installs sat nav etc Traced the none starting fault to a duff earth to the fuel pump He added an earth wire and earthed it properly to body.Took the car out and hells bells never in the three years of owning the car has it run as sweetly as that! unreal,exhaust note sounds much better and it was good before! very very happy!

Something worth checking for all those with running problems..... your fuel pump earth.
If it is duff, cleaning it up will give the pump more voltage and the engine more fuel (regulator allowing )

If you're not mechanically minded, it might be best left alone as fuel + sparks = boom :shock:

Try reading the fuel pump how to in the how to forum, it should give you an idea of where it is and what's involved.
