I have a '91 rs camaro, with an '88 TBI 305. I changed wiring harness also. The car was running great, then it just wouldn't start back after I shut it off. It has 14psi of fuel pressure, and it is getting fire. I even changed the ECM. but still the injectors won't fire. I changed injectors(used set) and still won't start. It will burst off for a second if I put fuel into the TBI itself, but then it will go dead again. Please help!
