Title: engine wont fire after remap mk3 gti AGG
Post by: 1981t25gti on 01 October 2014, 13:26

hello

i recently had a performance chip fitted to my ecu on my mk3 8v gti AGG , when i plugged it all back together i noticed that when i turned the ignition key the fuel pump didnt prime , and it didnt start , i took it all out and fitted the old chip but it was just the same , i had it back to the tuners for checking and they said its ok , it must be the loom or the ecu plug , i tested the voltage at the coil of the fuel pump relay and it was as low as 2v which wont pull it in , so i put 12v onto the out going side to get the fuel pump running but it still wont fire , any clues ?

cheers dave

Did they not re solder the metal box cage in.
You need to your re teach your immobiliser with a chip change
Or they have just ruined your ecu who changed the chip.

Sounds like they have blown your ecu
