Temporary no-start?
Very strange. (or is it welcome to the 928 club).
Came home after getting a little fuel (like $10 @ 1.76/gal is a little), pulled in the driveway, turned car off. Went to restart 1min later, sounded like it wanted to, never did. Tried again, was not gonna start. (checked fuses quickly, all were ok.....fyi, replaced the FP fuse 1week ago). Now 5min has gone buy, started right up.
Any possibility the fuel pump is about to push-up-daisies? Thoughts.
One other question. Should I be able to hear the pump when key is turned?
Thanks,
Bob

What does "sounded like it wanted to, never did" mean?
Did the starter engage, did the starter solenoid make a clicking sound, did the engine turn over but not catch?
C'mon dude, we can only help based on the info you provide.

Randy. Yes.
Starter....etc worked fine. In-fact it was sounding like it was just about to kick in, then no dice. (car typically starts immediately). The 2nd time engine cranked but no start.......That is when I checked the fuses because last week I replaced the fuel pump fuse, suspecting it again. (which it was not). During that time about 5minutes had passed, the car fired right up.
I'd have to say it sounded more like no fuel more than anything.

....just remembered. One of the times it ran for 2-3 seconds. Possibly the relay? (sure looks like lots of posts on this subject).
From what I was seeing. I need to basically hear the fuel pump run for about 2seconds (or so) when the key is turned on (not started) which pressurizes the system.

To hear the fuel pump, bump the ignition over without starting the car.
Go with the easy thing first - relay, and check that fuse again - I've had bad fuses in that location that looked OK.
See the 'Fuel Pump Relay' topic above.

Check the Greg Nichols site. some specific stuff on hot-no-starts, could be check valve on the fuel pump stuck in open position letting fuel pressure 'line' bleed down.
If you get to that point and your check valve is on the end of the fuel pump just pull it and clean it -spherical bearing - then try again.
Before I step all over it here...
I believe the 78/79's had two pumps, and only one had the check valve - I'd bet on the external 'fender' pump.
The Nichols site should have the voltage service and drop test specs -multi-meter-.
You can have someone turn the ignition -no start-
while you listen at rear of car after pulling the cover.
Another longer way to check is to clamp the fuel feed line at shutdown wait 15 - 20 min. if it starts right up you have either a bad pump or pump has bad check valve.
