89 tbi running & starting problem

[maynardtruckin]

Ok I have a 89 chevy 1/2 ton 2 wheel drive tbi 5.7l with manual trans. Here is the problem it will only start if I use either once it is running it is ruff idling at first the smooths out but falls on its ass when you give it gas until it dies or you feather the throttle and then rpm's pick up. Know I have replaced the computer twice, the coolant temp sensor 3 times, the ignition module twice, the fuel pump (and it has 11psi now), the throttle body once, and the engine wiring harness. It is not throwing any codes or this would be easy. Almost forgot it smells like it is running rich. So if there are any thoughts or questions let me know? Thanks!
