Well I just swapped in on 03 ecotec in my 02 sunfire.

Fuel Pump Is working.

Gas is in.

Battery Is charged.

I tested the fuel injectors and they are not grounded. Where should they be grounded to? Perhaps the fuse is blown?

I am positive this is a problem with the injectors, please help me, its been a week since i have driven my car, and well at this rate, its never going to run!!!

Can you look at a friend's car for how this is wired ?

Injectors are connected to the wires on the harness. There is no other way for them to work.

did you test the harness with noid lights? If so the injectors may be stuck closed. Did you check the resistance on the injectors?

Holy old post. You must be bored.

yeah, if he hasn't gotten it figured out by now.....he's in trouble...

Problem is I keep searching for ways to diagnose my own car and reading similar posts. I guess I get post happy or something and respond. This is what I get for using the search function..... Kind of an inverse result of whats expected.

They get there ground from the PCM, PCM determines injector on-time

I imagine the poster's issue was theft lock related. Not meaning it was kicking in, but the ECU did not reconize the ignition switch. We have had this happen and had to swap the ignition switch then theft lock kicked in did the relearn and all was well.
