I am new to this site and it was suggested I get started by posting in the lounge. I sought out this forum because I have problems with my 1991 Z-28 when attempting to restart it after it is at operating temperatures. It has a TPI 383 with a 5 speed. I believed the problem to be in the ignition and removed all aftermarket parts Accel coil, cap etc and replaced everything with stock GM parts including the distributor. Then I was suspect of the fuel system, sometimes I hear the fuel pump and sometimes I don't when restarting. I put a noid on the fuel injectors and somtimes the signal is strong and somtimes its not. I have had every diagnosis under the sun from possible vapor lock to a bad fuel pump relay. I am only trying to narrow down my plan of attack by someone who may have experienced this very problem and has a suggested fix. I have an ATI procharger with three core intercooler sitting on my work bench which I will be installing this winter and will be biting the bullet on a complete ignition / fuel management system computer programable. I just don't want to be going in circles with this issue when its a common problem.

Thanks 1991 z28 ragtop
