Chevrolet Camaro IROC-Z: I have an 88 Iroc with the lb9 5.0l

Customer Question

I have an 88 Iroc with the lb9 5.0l TPI. The car ran fine when it went into the garage and after sitting for the winter the car would start fine but not idle and miss a lot through the whole rpm range, after 2 days it would not even start. It also has no codes stored. I have fuel pressure and new fuel, replaced the coil, cap, rotor, plugs and wires and it now sputters and trys to start every 8 revolutions or so but wont start.

I don't have a gauge, I depressed the detente where you would attach the gauge and fuel sprays out about 6-8''. I tried ether when starting and if anything it tries to start better without it.
