There were zero issues when I parked my van. The next morning I had a Crank/No Start.
Checked ALL fuses and electrical connections. All good.
Replaced the ASD sensor, fuel pump relay.. No luck.
Hot wired fuel pump.. Good.
PCM wasn't relaying info to fuel pump relay.
Sent pcm for repair on warranty .
2+ months SIA ELECTRONICS out of Illinois told me THEY bench fried my OEM PCM and that they would send me a replacement.
Eventually it arrives. I plug it in and expect to be hauling ass shortly.
Nope. No start.
My OBDII only mentions that my exhaust system (yellow led caution) is compromised,, most likely because my airflow system is currently disconnected)..
Because I am committed to keeping this van until I'm dead -
I've replaced EVERY No Start Viable Sensor, including all sensors involved with the throttle body.
New plugs, wires, cap, rotor, pickup, Crank sensor, throttle position sensor, and more than I can recall right now.
Big question in my mind is.. Did SIA Electronics mis-program my PCM ?
PS
We're talking about a 2003 Dodge Ram 3500 Van w 360 v8 (5.9) Chrysler and just over 115K miles on it.
