Is it the fuel pump?

Asked by MyraD Jul 13, 2017 at 04:50 PM about the 2003 Chevrolet Suburban 1500 LT 4WD

Question type: Maintenance & Repair

I have a 03 Chevy suburban. Been having issues with it. I wake up in the
morning and it will crank right up, but it dies while driving down the road. It
takes an hour or so before it will start back up then dies a little ways down the
road again. I've gathered that it could be something with the fuel pump or
regulator, I'm not sure really. Just trying to figure out what to try first before I
spend too much money. Ive read alot online but haven't quite found a issue like
mine. I would appreciate any input.

Have you looked at OBD2 data with a scan tool for thrown codes from the cars computer.

MyraD, You need to determine if there's any spark, and or if there's fuel pressure when this problem occurs
