Not starting when warm

Asked by GuruC5WJY Feb 06, 2019 at 04:39 AM about the 1993 Chevrolet S-10 Tahoe Extended Cab RWD

Question type: Maintenance & Repair

Starts cold great, runs fine. When you turn
her off she will NOT restart without a crap ton
of starting fluid. Finding my Injectors will not
fire until the truck restarts via starting fluid.
Injectors fire upon cold start. Have replaced
fuel pump, fuel filter, and fuel pressure
regulator. Upon removing the regulator, I
found the fuel between my injectors in the
picture attatched was bubbling. Obviously it
doesnt bubble on a cold start so thats what
Im pointing my issue to. But I cant figure out
whats making it bubble. Temp sensor reading
fine. Unplugging sensor also doesnt turn the
truck on. She just sits and cranks with no
injectors firing.

make sure the fuel lines are away from the exhaust/converter , see if the fuel pump has a good ground
