JUST PUT A NEW ENGINE IN MY S2 AND IT WONT START IT TURNS OVER THERS A GOOD SPARK EVERTHING IS CORRECT LEADS PLUGS ETC THE PETROL GAUGE IS JUST ABOVE RED BUT ON NUMBER 2 PLUG THERE IS QUIT A BIT OF FUEL COMING OUT CHEERS IN ADVANCE

 

igntion timing and plugs on correct firing order?

 

YEAH THER ALL FINE

 

U say only number 2 is overfuelling?

 

other than that is the multi plugs on the inlet manifold!


on the correct sensors?

 

YEAH NUMBER TWO IS OVER FUELLING ALL SENSORS ARE CORRECT

 

Either your metering head is fucked or you've got a dodgy injector.

I had a problem with mine over fuelling on one cylinder and it was the metering head. Mine was number 3 although thats just pot luck

Mine still ran fine however just backfired an awful lot

 

NOT SURE IF IVE GOT THE METERING UNIT INJECTORS WIRED UP PROPERLY WOULD THIS MAKE A DIFFRENCE

 

Oh, hang on is your car EFI?

 

NO ITS MFI KE JETRONIC

 

Oh ok

wasn't too sure what u meant, do u mean then ur not sure if u got the pipes on the right connectors? the injector pipes it makes absoltely no difference, but they should only really go on in one order easily.

Metering head or injectors is what i would put my money on

 

YEAH IVE GOT THE FOUR MAIN INJECTORS CORRECT ITS JUST THE LITTLE RED INJECTOR PIPES ON THE SIDE NOT SURE ABOUT IS THER ANY WAY OF TELLING IF ITS THE METERING UNIT OR THE INJECTOR

 

just double check the firing order form this diagram!

also try reseating the injector that u think is over fuelling as air leaks cause overfuelling!

 

HOW DO I RESEAT THE INJECTOR

 

you could also try changing over no2 injector with another injector. See if no2 continues to over fuel, if it does then it would point towards a metering unit fault.

 

If you want to identify whether its the injector or metering head, swap the fuel connections over on the metering head (will be tricky though as u will have to sort of force the pipes over to different connections), if when swapped number 2 still over fuels, it would be the injector, and if the fuelling problem swaps to another cylinder it will be the metering head.

As for the injector seating its almost impossible to seat them wrong, that said i doubt u have even removed them anyway?

Do urself a favour and go EFI, KE Jetronic is PANTS.
