Hi guys. Its wiring so i'll try keep it short and sweet. Got the vr bolted into the car yesterday and started the wiring. Tried to turn it over to day and nothing, but the solinoid is getting power because we can hear it clicking away. We took the starter off and tested it with the battery and it works fine. Im a bit concerned as we cut some of the wiring away, which we thought wasnt needed, but we think my be now. Any help guys? Thanks

Does the fuel pump prime when you turn on the ignition?

Just for clarity,

The engine doesnt turn over at all??

Do you have a decent earth (negative) connction made to the body?? Which ECU are you using? Does it have power??

Right, got it turning over (bad earth) but now it isnt starting. There is spark, sh*t loads of fuel, and loads of power in the battery. Thought it was maybe needing back pressure from the downpipe so we bolted that up but still no joy.

Its me and my mate building it and we are only 16 so any help is much appreciated

If theres too much fuel it won't start, is the maf plugged in and working? Have you got the lambda plugged in and working?

What have you cut out of the loom?

[rodney 17]

Also assuming your timing is correct...???

[Jordz 0]

Lambda and maf both plugged in and working. The timing is perfect as it was running before we took it out. I think it may be flooded but we did try starting it with the throttle fully open. I think we will take the plugs out again and let the cylinders get some air

16 and doing an engine swap. respect mate

Thanks guys-the funny thing is neither of us will be able to drive it once its finished haha. We are both learning on it aswell.

Took the plugs out and the arent wet at all, and also every one of them is giving a good spark. Any ideas folks?

check crank posiation sensor make sure its connected wont start if it not. what year is the engine sounds like imbolizer is functioning properly

Done a bit more digging last night, think its the injectors not getting power some how. They are working manually and when we put a little petrol into a cylinder, it started coughing. Dunno why thet arent working but will have another look tonight.

[rodney 17]

the system is fuel injected so may need to be pressurised. Will check...

hi

have you checked the wiring haness plug on the side of the engine some times terminals corrode or check its cliped together correctly.

[Jordz 0]

Yeah, the cylinders are defonatly not getting fuel, although the fuel rail is. Em yeah, the connections are look fine, and its getting a spark so i think that means its ok? Might try putting on a vr fuel pump from my donor car tonight, see if that makes a difference

[OEM+ 1]

hi sounds like no power to the injectors if your getting fuel to the rail its not your fuel pump. did the old engine run before you changed it

[Jordz 0]

Meant to say, the injectors are getting power (pulsing). Yes, the engine was in a running, '97 donor car

[OEM+ 1]

was the orignalengine running before you replaced it with the donar engine

[OEM+ 1]

ment to say is the top inlet manifold on, an intake pipe from the maf to throttle boddie conected coz if you say injectors are firing an your getting fuel an a spark it should start

[Jordz 0]

Thought it may be the fuel not getting enough pressure though OEM?

[OEM+ 1]

you can try it wont hurt one more thing to cross of the list other than that im out of ideas at the mo

[AJmk2 2]

What was the original mk2 engine ? if it was any carb based engine then the fuel system will not be high pressure enough. You will need a fuel pump for injection along with checking all your fuel lines as some may need replacing.
