I am a woman and dont know a whole lot, but i put the fuel pump on, thought it might be that and changed the fuel filter, the problem is that while driving or idling the car shuts down. Then in about 20 min, or so it starts right back up. Sometimes i can drive all day and this dont acure, other days it does 3 0r 4 times a day, i need to get back and forth to work, i even had a new computer put in it. Help me plz, i dont know how to do much other then what i did and my late husband taught me that. I am out of my knowledge zone on this, i knew i should have become a mechanic

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

Debbie I have read your question vary well explained I would add .
After about I would say try changing the fuel filter again .
The reason being sediment in the bottom for the tank this is a 94 that's 22 years of sediment in the bottom of your tank then you disturb it by replacing the fuel pump.
We know the pump is new yet it runs sometimes and not others its also fuel injected witch means 60 of the fuel sent to the injectors is sent back to the tank its a high pressure system .
COPY THIS bring it to your shop let them read it .
