Venture stalls when at operating temp
Hello all. I have a 2002 Chevrolet Venture ext length. When the vehicle reaches operating temp it will stall and quit running. Sometimes it will start back up and run ok. Other times runs very rough and backfires. Sometimes won't start at all just turns over. Below I have listed parts that have been replaced
Both crank sensors and relearned
MAF sensor
MAP sensor
ECT sensor
Spark plugs and wires
Fuel filter
Pcv valve
Oil presssure switch
Fuel pressure regulator
I did check fuel pressure goes to 50 lbs KOEO. While running is ab 42-45 lbs (I'm assuming the fuel pump is the issue since spec is 52-59)
Checked connector behind driver seat no problems seen all connectors clean no dirt or debris.
Below are some things I've noticed
long term fuel trim was reading -17. I assume this is the issue not sure though.
Ignition relay is pretty warm. However no fuses have blown so the warmer than others on this relay maybe normal.
Any help would be greatly appreciated.
