Help. My friend who is a vet with PTSD has a 1994 Sephia. It passed smog (Calif) and the next day it would not start. Checked for a spark and it was a good one. Pulled the fuel line at the point where it intakes to the injector line and it pumped out well. Disconnected the exhaust pipe and it still won’t start. Any suggestions? He needs it to get to work. I’ve been driving him.
