    I was cruising down the highway when my 2000 sierra just died, the battery light came on in the message center. The truck cranks but will not start. My first thought was fuel pump but that didn't fix it, any ideas? Thanks

    Usually, the fuel pump gets power from the fuel pump relay. As @geo1 asked, can you hear the pump running?

    I think the fuel filter, on that truck, is in the tank, changing the pump, is a chance to clean/renew the filter cloth.

    And, as geo1 suggests, the problem may be spark. The other possibility is air (you need all three) check the air filter and ducts

    And, while typing, I'm thinking, does he have fuel?

    Ray......On a 2000"s.....The Fuel Filter's are located, on the inside of the Fame rail, on the Driver-Side.

    Thanks Mike, that could very well be the problem. OP, do you know when the fuel filter was last changed?

    check the fuel pressure with a pressure gage you need more than 50 psi for eng run.

    could be the crank sensor under the starter . check for codes first .

    it could have been a fuel pump but normally they do not suddenly fail. crank sensor can suddenly fail.

    wiring /connector/ and metal contamination can cause this issue.
