331 stroker, EFI...first started a couple months back...wasn't running great, but was running...I cleaned up all of the KOEO codes (11 code), and was working on the KOER codes...replaced O2 sensors, etc...but now it won't start!
Cranks, but no fire.
Put another 5 gallons of gas in the tank...getting about 42psi at the donor fuel rail shraeder type valve.
Fuel pump runs for 3 seconds when then key goes to Run.
Test bulb flashes on center post of dizzy while cranking.
Test bulb also flashes on #1 plug wire while cranking.
Didn't look for spark at the plug itself...would I be able to see a spark across the gap while cranking?
Fuel pump runs for 3 seconds when turning the crank with a 15/16" socket with the key in Run...I assume this means the TFI is working? Perhaps there are other elements in the dizzy that could still be suspect?
Pulled the dizzy, with the shaft grounded on the intake, key at Run, the fuel pump again spins up for 3 secs as I slowly spin the shaft by hand...and I can hear the fuel injectors clicking as I go around.
So I'm stumped...what other trouble shooting should I try?
Thanks,
Brian
