Fuel pump pressure for 1989 buick reatta 3800 engine

SOURCE: starts then dies

check your fuel pump relay 

SOURCE: will start then dies

On the regals they have a ceramic resistor on the passanger side under the fender. It heats up and over time it tends to brake and the wire inside tends to rust away. The fuel pumps run in 2 different speeds. Had the same problem. Dealer only part yet the car would run and you would think it was the fuel pump. Turn the key it kicks on then start and dies out. Ceramic on the pass side would need replaced. It is white about 2-3 inches long or so held on with 2 bolts i do believe. Ill find a bulliten i found online to help me diagnos the problem. :) hopefully this helps someone out instead of spendin $$$ that ya cant afford with the recession eh?

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.
