Your problem may be in the connector where it plugs into the sending unit if the terminals are spread and not making good contact you will have voltage drop and cause the pump to overheat.

check with your car Quest dealer and see if they have a pig tail that you can solder onto your harness this will most likely solve your problem

I know where my relay for the fuel pump is under the hood, but isent their a relay reset button?

no reset on relays --relays can be affected by heat and pop open shutting off fuel pump than when cool will allow restart - remove relay and check pins that they are clean --can either buy a new one and install or keep handy in glove box --also recheck pump new dosent mean free from defects --and wiring connections are clean and not damaged and look online for repair assistance lots of repair information available or amazon ,craigslist or ebay for a repair manual for the caddy new ones in store about 25 to 30 but can find one from 5 - 25 online a chilton or haynes also most used book shores sometimes have a number of repair manuals for caddys and last but not least you have the library that have some manuals and sometimes have one for your vehicle

1990 cadillac fleetwood die when iddling and sputters at stops.

Sounds like you might have a weak fuel pump.You need to check your fuel pressure you didn't say which engine it has but if its a 5.7 you need 9-13 psi with the engine running.If its not within the specs then replace the fuel pump and filter.

I have a 1994 Cadillac Fleetwood, How do I determine if the fuel pump is bad or the fuel pump relay?

Replace the relay as they are fairly inexpensive and if that doesn't solve the problem the pump located in the gas tank may need to be replaced. I'm assuming you have first changed the fuel filter. Also if there's water in the fuel add some Heet fuel additive to disperse the water and also add some fuel injection cleaner to the tank as it can't hurt.

Fuel pump not comeing on 1998 gmc jimmy how to test the pump?

this is the highest failure rate of any part. I've been in auto parts for nearly 10 years and one thing is certain, you need to replace your fuel pump. Do not get a Carter brand pump. ONLY get a Delphi or Genuine GM pump. The less expensive pumps last about 1000 miles.
