Sorry i missed your other post ..
Wiring going from the VP44 to the ECM is not seeing a connection IMO
Check your grounds & connections
Run a Jumper cable from your engine pulling hook/loop by #6 Cyl to the neg battery terminal to try to crate a solid ground

I cleaned and painted all the grounds not too long ago, so they should be good. Does the ECM ground of of it's mounting bolts and the back of the housing? I will try the jumper cable in the morning.

The Engine pulling hook is a nice soild raw medal piece to clip your jumper to and when you connect the other end to your neg terminal it ground the engine Something to try
Good Luck

I've got the same thing going on with a guys truck I'm working on, turned out it was the ECM, waiting for the new one to get here. If you know someone with a 98.5 to 02 borrow their ECM and try it, if it fixes you need an ECM, if not check the harness.

He means check the wiring harness - check for bare spots where the wires rubbed etc., There could be possible shorting issues.

I will look at the ECM harness. Is it easy to pull the ECM and clean it's mounting points? I went out today and did the jumper cable thing, cleared the codes, checked all of the fittings and hose in the fuel system, and started it. I drove immediatley to the gas station a filled up with $3.29 #2. Still running good. Drove to NAPA, about 5 miles away, and had no problems. I pulled the codes when I got back out, and I got a P0122.I cleared it. It started fine and drove back to school fine. I checked the codes when I got back, and the P0122 was back.
