would anybody happen to know where the injector modulator would be at? i put a new hpop opr icp and im had up too 750 psi of oil but the injectors aint firing any ideas?

 

injector wiring harness?

 

what about it? is that where the modual would be at?

 

i THINK the module is driver side on wheel well inside. .... but did u check the wiring harness to make sure everything was connected right and there were no cuts or anything in it?

 

there shouldnt be i was driving and the truck just died and i replaced all that stuff, were would the harness for it be at??????

 

The injector harness is under the valve covers and runs them. See if anything vibrated loose. Make sure you unhook both batteries all cables cause I believe they run very high power and can kill you

 

well i put my idm on another truck and his fired right up. im thinking i got sold a wrong and/or bad icp,

 

Did you check the fuses??? The fuel bowl heater can short and cause a no start issue... I'll have to go back and re read this thread...

have you tried unplugging the ICP sensor and starting?

You swapped the IDM? From inside the wheel well???

 

no fuses are blown and ive changed the icp hpop opr and yes ive swapped the idm from the inside of the wheel well.
