1999 Chevy Suburban k1500 138,000 miles 5.7 L Vortec engine
vehicle was driving perfectly, accelerating smoothly, plenty of power prior to this, even driven that morning. Stalled at red light on 11/1/12 and has not started since.
no backfiring, no sputtering, no misfiring, no skipping.
sounds like it wants to start, but will not turn over
timing chain tested by getting the #1 cylinder up on the compression stroke and rotor button sitting on #1 cylinder/plug wire and it is working
all fuses working
getting good white spark
Ignition modulator replaced
throttle position sensor replaced (handheld scanner threw only this code)
fuel pump has 62 psi
sending unit appears to be working
will not start even when spraying ether on it
security light is on and steady when trying to start
Could it be:
idle air control sensor?
