Hello.! I’ve been researching and reading and trying things I have found out about a pcm/no bus.

My car died. I thought I ran out of gas. Put gas in it. Started it and it died again. Changed battery, alternator, pcm, crankshaft sensor.

when I put the new pcm in. Said no bus, changed crankshaft senor still no bus and wouldn’t crank, unhooked my water sensor, it fired up runs and dies. It starts even with the no bus on.

I put the key in. Turn it over and on. It runs and idles, then the engine light comes on the air bag light comes on the red circle light comes on, and shows no bus then stutters and dies, but can turn right back over and circle through the same senario. It might need flashed, but I got a pcm vin programmed when I bought it, had a couple of connector pins pushed back fixed them still has the same issue. I have not unhooked the camshaft sensor. But I’m at a loss. It might need flashed?
