I'm away from the vehicle this morning. We confirmed good spark yesterday. We get fuel at the schrader valve on the fuel rail, but it seems weak. We are a lttle suspicious of the new fuel pump we have installed. It is definitely louder than the original pump. Planning to try testing the fuel pressure later today.
Codes are 12 21 55.
Yes, check the pressure. Did you replace the fuel filter?
Trouble code 21:
I doubt it would cause a no start condition though.
The NEW fuel pump we had installed was bad. Apparently it was pumping fuel, but not putting out even enough to even show up on the fuel pressure gauge. Installed the second fuel pump and it is running great now.
Thanks for your help along the way.
