Exclamation My 94 z28 wont run right dont know why?? HELP

A couple of days ago, my problem started. when i start my car and give it gas it boggs all the way down. I have to tap the gas a littler bit, very little. if i give it too much it just tries to die. Then about 30 seconda later it would run fine. I was driving down the road, and i was giving it gas and it died, I pulled over and 2 minutes later it ran fine. I bought a new fuel pump, thinking that that was it, but NO. It has new fuel pressure regulator, new fuel filter. Now my camaro wont start at all. Is there any sensors that may cause this??

Yes it's possible there is a port under the dashboard to the left of the steering column. You just need to find somebody that can scan OBD1 since it requires a different connector I believe.

94 is OBD-I and has a "normal" 12-pin OBD-I ALDL connector. Can be read with any OBD-I scanner. It's the 95 that has the 16-pin connector.

Or get free scanning/data logging software and a low cost cable:
