Why won't this thing start?
4.0 engine coughs, sputters, backfires when starting. Once running, it runs and
accelerates fine, even at high throttle settings.
Was giving codes for Cam position sensor, Crank position sensor and oxygen
sensor. Replaced all 3, no change. Replaced the PCM, no change.
One mechanic suggested fuel flow issues but I can swell raw fuel, if cranked for
a while and, as noted earlier, runs and accelerates fine.
Any Ideas?
