03 intermittent starting problem

[JBeasley]

A friend of mine has an 03 auto with about 70,000 on it. His only mods are an EZ and exhaust. In the mornings when he starts it he'll let it warm up a few minutes and when he leaves the house he'll only make it a mile down the road and it will die, but it always starts back up and runs fine. It only does it before it reaches opperating temp. Is this a sensor problem? If so witch one. Thanks for the help.

If he has already changed the filter then it is either the lift pump or bad injectors. At least that is what it was for me.

For troubleshooting purposes I would unplug the Edge. then try it . If not put a fuel pressure guage on the pump as DE Jeeper thinks it may be. Thats the cheap stuff to do. It should be covered under the 7/100k engine warranty

I haved the same problem with mine ,after a lot of parts change(lift pump, ecm, injector,)the dealer replace the fuel limiting pressure valve and finely run good.
