Think my relay went/ is going. It takes some cranking to get it to start cold. Believe the battery is fine. I turned the key on and off a few times and heard the pump only once and haven't since (heard it the third time I tried I think). I do hear a relay clicking though. Starts fine warm and runs great, just want it perfect I did run out of gas yesterday due to a faulty gas gauge but I would think that would damage the pump, not the relay correct? Since the pump is cooled by the fuel.

Do you have a duke or a 2.8 6cyl ? If a 6, could be the cold start injector not working.

Yeah I have the 6cyl , I hear a relay clicking but not the pump, heard the pump once thats it. Are there any other relays I could be hearing?

Looks to me that you damaged your pump. You can change the position of the relays behind the driver's seat....they are both the same. But if you hear clicking, chances are the relay is working and the pump is no longer workable.

But it wouldn't run right if it was damaged right? It runs fine once started.

The FP relay could be faulty....or perhaps it's the connector base or wiring. Sometimes they get corroded.

I'll check it out tomorrow thanks, I'll swap the fuel pump relay and the a/c relay and put some dielectric grease on the connectors.

The cold start injector doesn't fire unless coolant temp is below 35°F.......

Been cold in Florida lately?

Quick update between classes, I heard the pump come on and it started on the first revolution this morning so the problem seems intermittent, I'm going to take a look at the connections later today

I DO live in Fla, and the 2 fiero's I had with 2.8s, the cars DID start much better WITH the cold start. And no way was it under 60 degrees. disconnect the cold start (Motor cold, had not run in a day or so,) and the motor would crank for a few seconds when cold, not so when the Inj sensor was plugged in

Took some cranking after school , what's the best way to get at the relays?

its on the fire wall right behind the drivers seat. You could take out the air cleaner box if you want.

what you really need to do is stop guessing and get a fuel pressure gauge to see what exactly is going on with the fuel.

*if you need GM relays or just want to change them due to age ..I got mine hassle free at amazon.

The cold start injector switch is thermostatic; i.e., it is open above 35°......no cold start injector.
My son had a similar issue on his Formula.......after replacing the timing chain the engine fired immediately.
