R34 Won't Start After Fuel Pump Install

[DoseVader]

So I bought a nismo fuel pump for my r34 gtt pretty straight forward installation as its a direct replacement pump. Put everything back together went to start the car and wait for it nothing. Can hear the pump priming but the engine isn't ticking over at all.

Any ideas? Nothing is leaking pump is priming so why isn't it starting?

Going to have another looking in the morning so hopefully i can work it out.

Thanks

Fuel lines on backwards.

Nope my fuel lines are marked so that wouldn't happen

Well what else do you suggest?

Did you mark the in tank lines also?

[DoseVader]

yep 3 lines

1xcircle shaped line = black
1xelbow shaped line = orange
1xeblbow shaped line = yellow

joined them all back correctly

back to black
orange to orange
yellow to yellow

so can't see how that is wrong hmmmmm?

Check you have fuel pressure with a gauge.

It has to be related to what you did.

[DoseVader]

ok fuel is getting to the engine cause i unplugged the fuel filter and turned the car on to full accessories and a heap of fuel came out?

[Ben C34]

So it was running fine before?

All you did was the pump?

What do you mean by not ticking over?

[Ben C34]

What side of the filter did fuel come out?

You could still have made a mistake with the lines.

[DoseVader]

yep was running fine before this and yes all i did was the fuel pump. By not ticking over i mean it doesn't even attempt to start nothing.

I have a nistune but surly this wouldn't effect it to the point of the car not turning on

[Ben C34]

So it doesn't even crank over?

[DoseVader]

nope nothing.

[Ben C34]

Ok.

In that case alarm?

Fuses?

Did you prime the system lots before turning on? If some of the fuel has drained out of the injectors then they sometimes take a bit to get started. Key on and off a fair few times is the easiest way to do it. Key on, let it prime, key off, repeat

Also change your fuel filter in case the new pump has stirred up some crap thats got through the sock (not likely but id change the fuel filter anyway)

[DoseVader]

the car has an alarm system do you think somehow by doing this the immobiliser is stopping it from starting?

[DoseVader]

and yes i have primped the pump a lot and fuel is defiantly getting to the engine

If the car won't start:

1) Check battery voltage, you need at least 10.5v while key on start (yes actually turn it to START, even though you think nothing is happening, what could actually be happening is there isn't enough voltage to bring the solenoid in to engage the starter)
2) check fuses

3) check start relay (30 needs power, 85 and 86 need to energize a coil, so a test light between them with the key on start should light it up)

[DoseVader]

turns out it was the engine immobiliser works fine now

[Ben C34]

Lol

Derp!
