: no power to fuel injectors 01 catera

12-23-10, 05:11 PM
I have an 01 catera in my shop, fuel pump was bad, so we changed it, now fuel pressure is good, but we are not getting power to the fuel injectors..

now I'm trying to figure out if it is the cam sensor or the pcm, I have already replaced the crank sensor to no avail..

if you could help me or locate any wiring diagrams for me it would be very appreciated...

I have a 98 catera, i did the exact same things only to find out my ecm was bad and grounding the injectors. my problem was opposite...my injectors were constantly on. The injectors should always have power where the computer sends the ground to shut it on and off but i would definately think it could go the other way and not give it any power.
