92Red454SS
Newbie
I am the original owner of a 40K mile 1992 454SS truck. All original with no modifications.
The engine cranks excessively and once it starts it runs for about 20 seconds then stalls (sometimes). It will do this once or twice on restart. Additionally when it stalls it seems like it looses spark as it does not surge or try to keep running. The stall condition is intermittent, but it always cranks excessively to get it to start. No check engine light.
Naturally when I open the air cleaner to view the fuel flow from the injectors it doesn't stall.
In the past when turning the key to the on position the fuel pump could run for 2-3 seconds. Now it runs continuously for 20 seconds. I removed the pump relay and checked it for proper operation and it appears fine. Fuel pump was changed about 10 years ago.
I have read posts about possible faults being the ignition control module, coil, temperature sending unit, oil pressure sender, ground at thermostat housing, fuel pump relay. Any thoughts?
