Vehicle started then died and havent been able to start since. Notice that the service engine soon light stays on when key is in run position.. Any help appreciated. Tried checking andchanging out a bunch of fuses (ignition 1 and two and others to no avail)

The SES light should be on with the ignition switch in ON position. This is what they call the “bulb test” mode. You need to check for spark and fuel before we can proceed. One or the other is usually missing when it will not start.

I havent pulled any spark plugs but it did start once after this problem for a few seconds and then died. It seemed like a fuel starve to me. I tried checking fuses for fuel injectors and found nothing. The fuel pump at least goes through the prime cycle when I first turn the key on. This vehicle only has about 68000 miles on it . Also I changed the battery about a week ago. It is super strong because I have tried to start it probably way more than I should have. It still is not all the way down.

Be careful with the starter, it will overheat if you attempt to start too long, then you will need a starter! When things are right on these cars, they will start immediately, as you probably recall. First, check for spark to the plugs. Next, you need to get a fuel pressure gage and test the pressure. Let us know what you find.

I can probably check for a spark but I dont have a fuel pressure guage and wouldnt even know How to use it . I guess I will have to have it towed to dealer.. I will let you know how it comes out. Thanks for your help

When a dealer sees a car on a tow truck, all they see is $$$$$$$$$$$$$.

Had the fuel pump and control module and connector to it replaced at the dealer and this solved my problem..

I bet the problem with your pocket book $$$$ was not solved. Maybe it was in the dealers favor.
