LB7: Should i just burn it to the ground

[GMC_2002_Dmax]

I am having issues with my truck. For some reason it seems like when flashing a tune on the truck it won't load on the ecm... I start it and rev it up( it does rev up). Then i put it into gear and it won't go over 1200 rpm.. I tried loading up a lope tune and it won't lope. I have tried numerous things just won't run right.... AnYbOdY have any ideas?? Thanks

Do you have your MAF hooked up ???

Is his modified or stock ???

Is his a 2004 or another year ???

If you disabled codes for MAF or Overboost enable all DTC codes and MIL lamps and see if you get a DTC to set.

Pull the On-Star, Radio fuses.

Make sure the doors are shut, set the e-brake.

Some 2004 trucks will not flash correctly without pulling fuses, even though most do I have one customer I have to bench flash his out of the truck or else I have trouble.



Maybe flash your ecm in your buddies truck and see if it will then work in your truck.

I am sure you have checked this stuff, but fuel filter, fresh fuel, no obstructions in the fuel line etc.

Are you sure it is programming. Again I would check logs against the tune and make sure everything is right. I don't think it is a programming problem even though it seems like it.


Does it smoke with a smoke tune? Lack of fuel? Does it run/idle rough? Etc etc. I don't see it being an injector either if it idles okay.

If you decide to blow it up, and you absolutely wont sell it to me, atleast invite me to watch.

remove your glow plugs and spin the motor over. If the tips are clogged you will now it. How old is the fuel in the truck?

fuel is like 5 months old
