Car Information:
Chevrolet Suburban
Year: 1999
Engine Size: 5.7
Trans: Automatic

Issue/Question: Larry, we used to hear the fuel pump cycle when we turned off the engine. We don’t hear that now and it is difficult to start. But once it starts it runs normally. The pump is a year old and the fuel pump relay is new.

Answer:
Try turing the key on and off about 6 times, then try to start the truck. If it starts right up, there could be a problem in the CPI fuel system allowing fuel to leak out while sitting. We would recommend a residual fuel pressure test to verify if this is the case.
