Driving along and started sputtering like it was running out of gas. Luckily I was able to limp home. Replaced fuel filter (clogged), installed a TBI repair kit. Nothing has changed. Still sputtering when started and have to pump gas to keep running. Will not rev up. Being that it is a loaner truck, I do not want to keep buying parts that may not be the problem. Thinking it may be the throttle position sensor or even the ignition (which also may be the problem for the radio not keeping memory- returns to am upon restarting). Please, anything helpful at all? Thank you!

Have you checked the fuel pump pressure to confirm it is within the manufacturer's specs?

I don't know why, but this just showed up in my mail. Sorry it has been so long. Have you had any luck with the issue?
