If you crank it over & over, it will not start. You need to bump the key over & over to get it to start, or else it will flood. Will not start in "clear flood mode"
Replaced: Fuel pump Fuel Filter Fuel regulator Fuel Injectors Tested fuel pressure, very good Throttle position sensor Coil Electronic spark control Wires Cap & Rotor Plugs Quadruple checked firing order. ECM Cam sensor Checked for vacuum leaks around the intake.
I am at a loss of what to do next. Anything that could affect the running of this truck in open loop has been replaced (as far as I know)
On the scanner:... No OBD2 codes or faults. Everything is within parameters. No exhaust restrictions, no intake restrictions.
It sounds like I'm missing some other fuel control piece that may be the answer. Something is not telling the fuel to release above an idle.
As of now, the dealer is baffled.
