Also u may want to check the regualtor take to a mechanic and have him put i pressure guage and to make sure pump is pumping right amouth of psi. you could have broke some of the plastic on pump when putting in. If good psi then maybe relay or regulator under intake.

Check the fuel filter. if you take it off and blow through the end of it, air should come out the other side. if not, the fuel filter iss clogged. also you might wanna check the fuel pump relay/fuse. hopes this helps

Having problems with 2002 chevy silverado 1500 won't stay running. cut out going down hiway then died will run a while then die is this the fuel pump


Start with the simple and replace the fuel filter first. If it was the fuel pump, and being electric. It would have not restarted again if the pump has gone bad. The fuel filter should be replaced every 1,500 miles or once a year to ensure that your fuel system is running 100% and will not burn out your fuel pump early due to extra heat generated from working harder then is should. Good luck and keep me posted.
