Hey everyone,
I am chasing down a strange fueling problem. One thing I noticed was that the ECU was VERY hot to the touch. Much hotter than anything in its vicinity (including heater core). Is this normal?
I am datalogging and running under emulation w/ autoprom.
The truck runs runs very well but at random intervals it stops fueling. Then it runs terribly. Wideband pegs high at 22.3, BLM and INT both max out. So it's trying to fuel but for some reason it doesn't.
New fuel pump recently installed and voltage to pump reads good. Not saying this isn't a problem but seems unlikely. Truck never completely dies.
Thoughts?
