Help with 8v Gti Starting

[andd306]

well i took the hose off which goes to the injector rail and it pumps out when cranking! there seems to be a smell of fuel when trying to start it!

Also im 90% sure i can hear the pump priming.

The more i think about it the more i think it must be a fuel or ecu problem, because surely if the engine is timed up correctly and i have a full set of sparking plugs the only thing missing is the fuel?

Is there a injector test i can do or possibly something that can go wrong when disconecting the wires?

Is there a way of resetting the ecu?

The fuel pump priming is quite easy to hear I just checked mine on the way home. When you turn the ignition before starting there will be a hum from the back of the car for a second and half and then stop. To reset the ECU, disconnect the battery for 30+ mins then reconnect.

i can hear a priming noise coming from the engine area but not from the rear of the car! But when i remove the petrol pipe going into the injector rail and turn the engine over it poors out of the pipe so it look like there is a supply!

And everything is plugged back in ? Sounds like the injectors are not injecting the fuel if your getting a spark !!

Earth lead left off and spiked / blown the ecu by any chance.

Earth lead?

How can the ecu blow?

Poor earth and then trying to start it can spike the ecu and blow it, seen it happen on mk2's a lot.

any way of testing it?

Suppose if you could connect and read your ECU with vagcom then the ECU must be working, may also give you a clue as to what the problem is !!

Know anyone with vagcom ??

nope afraid not! everything else still works!
