Yesterday, my 94 XLT failed to start after the drive home from work. Lots of battery and cranking but no start. Could not hear the fuel pump running. Came back about 10:00 pm and it started like nothing was ever wrong. So what should I check ahead of the fuel pump to diagnose and eliminate whatever is defective; especially if anyone out there has had this problem, too? I would like to literally work back from the pump so I don't overlook something and have to go back.
Also, my temp gage fluctuates from just beyond the 'N' in normal down to half way to stone cold. The system is full of coolant, no leaks, the heater works fine so I know aside from the gage, things are working fine. I assume that once full operating temp is reached it should stay fairly steady and not fluctuate. Might it be a failing temp sensor from the block or something like that? It all began after I back-flushed the cooling system after I bought it.
Thanks for any help to identify these two issues.
