Truck loses power and shuts off, cranks but won't start.

Post by Countryasian »

Ok I've just replaced the fuel pump/filter yesterday and I was on my way to work when my truck lost power and cut off. I have fuel and all my lights were on. I went to try to start it again and it cranks but won't turnover. Can y'all help me out please?

Get under truck and put your hand lightly on the tank, not the shield. Have someone turn the key to ON only(DO NOT TRY TO CRANK) and feel for the vibration of the pump priming the system. You may even be able to hear it. If nothing you'll need to start checking wiring connections. Also check for spark at the plugs.

Did you do the upgrade wire harness pigtail when you installed the new pump? Check your electrical connections. If someone else did the upgrade, its possibly a poor connection.
