chek your catalytic converter , may be plugged ...

also , if someone revved the hell out of it could have knocked loose all the carbon in the combustion chambers , this will also make it not start or run like total shit ...


Thanks for the insight, I'm not very polished at engine troubleshooting. Catalytic converter is relatively new, only a few thousand miles. Not really sure how to check it or clean combustion chambers...

that's over my head then

what motor does it have ?


good thing that it passed before it messed up- my guess is that the timing of the failure is just a coincidence- it happens like that- could just be one of the usual suspects, that is a 20th Century truck and it should not be hard for a good mechanic to diagnose-
