My 1988 GMC C1500 Runs Good Until It Warms Up Than The Injectors Start Dumping Fuel Into It And It Stalls Out. We Have Replaced Alot of the sensours And The Computer and it still won't run right what could be the problem?

First of all, are you sure it's flooding out? Have you checked your fuel pressure? If you can let us know what sensors you have changed, it will help narrow it down. Also, you can check the vacuum line to the fuel pressure regulator to see if it is sucking fuel into the line. Please advise.
