Electrical problem
2003 Other Hyundai Models 6 cyl Two Wheel Drive Manual
----------------------------------------------------------------
I have a 2003 hyundai md-26 full size tiltbed truck that will not start. I replaced the fuel pump, had the starter rebuilt, replaced fuses, relays,and the truck cranks, but does not start. If you use either, it fires up but does not stay running. It has a cummins isb diesel engine. this whole problem i beleave started when the wiring in the fusebox was messed with to solve a lighing problem with the trucks tilt bed. I checked the fuel pressure, and its good, the fuel injector pump operates normally, so, I already eliminated that from being a problem. I'm thinking the trucks computer has to be fried. Thats the only thing I can think of, Got any ideas? I would greatly appricate it.

Hi racer71,

Check for for current supply to the fuel cut solenoid at fuel pump. Test and see if the solenoid is operating when ignition is on.
