Title: g40 conversion no spark no fuel pump
Post by: poloandyb on November 24, 2011, 09:43:24 pm

right im hoping someone can help with this....im putting a g40 into my mk2f van whitch started out as a single point.iv changed all the looms in the engine bay (white plug/black plug/engine)for the g40 ones engine turns over and iv got power going into both the relays at the side of the ecu but no power coming out so iv not got a spark and the fuel pump will not prime!!!!!!iv changed both relays three times and still the same,am i missing something im not realy that clever with the wiring side of things

so any help would be great

Why dont you use a multimeter and the autodata wiring diagram to check your loom without taking it out of the car?
