Dies Hot then no start
I have a 91 Silverado 350 throtle body with 220,000 mile on it. She dies when hot then takes 30min to start. when trouble shooting when dead has spark and cranks good. Just replaced fuel pump and filter. Getting frustrated. Also replaced the ECM today.... Same thing
PLEASE HELP ME....... Could it either be the fuel pump relay? or the injectors?

RE: Dies Hot then no start
Check the resistance across each injector, pull them out and see if they are firing. Why didn't you replace the relay before replacing the ecm, an ecm is like $300 and a FPR is about $14.
Have you checked for fuel pressure?
