Chime needs only a ground to work
So if that can help try to move the harness and look if chime work normally.
If it does then one wire touching the ground on and off (wire touching metal)

Hope it helps.

With a scanner that can control output
Look for TPS % data
If it shows 1 or 2 % (no fuel pedal depress)
Reset it
It must read 0 % (no fuel pedal depress)
Run the engine to check if the problem is solved.

1997 gmc jimmy brake bleeding -khpbmhaocwhdo3b0pqdplrqt-5-2.jpg
Brake bleeding Procedure
1. First, you have to depress pin location (see Image)
Keep this pin block so it will not pop out during the bleeding otherwise air will stay trap inside the system.
2. Start bleeding the Brake cylinder that is the farthest from the Brake master cylinder. Do the 4 wheels in the same matter.

Hope it helps.

You will need to have the inner door panel removed to be able to access the actuator rods.

Just a thought.. try sliding some shim stock down the shafts to move the stops out of the way. Feeler gauges like those you use to set points or sparkplug gaps might work..

You are jumping to conclusions. Slow down.
No spark AND no injector pulse indicates none of the desired outputs were triggered. The ignition module makes spark when it receives a crankshaft position sensor signal, and then transfers control of that spark to the computer after it starts. The module takes its crank sensor signal and generates an RPM count that it forwards to the PCM(main computer) which is used for triggering the injectors and controlling timing. SO, if you had a bad crank sensor OR a bad ignition module, you could lose both spark AND fuel. a coil would not disable injector pulse. modules RARELY fail in a manner that disables RPM reference to the computer causing it to not fire the injectors...At this point, I would TEST the crank sensor as the next step. If its easier, 1 of the wires on the module goes directly there so you can test the crank sensor at the module.
