Hi Dave just bought a Gsr and is having some problems :evil: , for what we can figure injector 4 is not firing. Have put my laptop on it with the data logger and there is a injector circuit fault code, swaped the ecu with danes gsr, fault still there. Does any one have or know where I can get a pin out for the gsr ecu.

Yes we have spark and have done a compression test, aok. Turn injectors of one by one and 4 makes no differnce, also can't physcialy feel it pluse. Injector impedance is 3 ohms same as the others. Don't really feel like trying to meter out the loom to ecu pin one by one, am lazy and hung over :cry:

Help me T4G your my only hope :lol:
 
problem still occurring but only at low rpm when airconditioning is on and car struggles to go when foot is put down while driving
 
chech your earths! I don't think GSRs run a too complexed injector circuit so really you should be able to find it with a multimeter

can't remember but i think they switch earths not B+

I know earths in the engine bay are critical with most EFI cars and they can do some strange things, The earth may have no direct connection with the injectors!

Have you tried a different injector? or even swaping it to a different location? and see if the fault differs?

just some ideas
