I have a 1997 chevrolet silverado, 5.7 v8 engine. I put in a new gas pump but it wont start. It says the gas pressure is low. The cables also have very low spark. Any advice on how to fix these problems? Thanks :crying:

What is the fuel pressure with the key on engine off & when you are cranking it ? How did you determine it has low spark ? I know some Chevy fuel modules are crapola. Had to replace two before I found a good one on a 99.

Go delphi with lifetime warranty, plus check your power and grounds.

When you/before you , replace the fuel pump always check pressures and VOLTAGE/GROUNDS TO PUMP CONNECTOR...

this is required as you,,,possibly, and others have found may have been the problem of low fuel pressures...

use of a meter to measure the voltage and ground security is required...many fail to clean and fasten the ground point located on the frame...

I replaced my fuel pump earlier this year and I did it my self
I put in new pump ad truck would not start I cecked fuel pressure and it was about 16lb's and the minimum is 60lb's so check to see if the fuel pump is correct my truck is a 97 k1500 with a 5.7 motor
