Car dies while driving

When the engine dies all the lights on the dash should come ! It's when the engine is still running an those lights come is when you need to worry ! You need to check for spark an fuel pressure. If no spark probably an ignition module , crankshaft position sensor or distributer module , what ever ignition system it has. If there is spark spray some carburetor clean into the engine , if it try's to start you have a fuel delivery problem , fuel pump , relay ! No Start Diagnostic Basics EricTheCarGuy

Find the security system and write down the make and model. Use internet to find owner's manual, or how to disable the system.

pull oil cap and look in valve cover and see if you can see valves moving chances are if it died when driving you may need to rehome your idle speed control try turning key on engine off for 10 sec on 10 sec off for 6 to trys and then give it about half throttle and try to start and see if it runs if it does see if it idles if it dont idle try the 10 on and off a few more times

it has 2 fuse boxes. one is in the engine bay and the one you want is
under the dash, left of the steering wheel.
you will need fine needle nose pliers, a light and your glasses.

Check battery cable connections to battery, chassis, engine, and relay box.

What was the code you got,after the sevice soon light came on,and you had the code pulled?

While you are driving the truck just shut down like you turned the key off ?
And now it will not start ?
Do the lights come on in the dash when you try to start it ?
Can you turn your headlights on ?
Is there a check engine light on in the dash. You need to have someone hook a scan tool up and retrieve any codes you may have.
Please let me know.

You may have one of the most common issues...sometimes, by accident, the dimmer control on the left side of the dash gets turned down; it is the little wheel at the far left of the instrument panel. Try turning it up, see if that fixes your problem; we see this issue quite often in my service department.

I had this happen to me before. My battery had went out and I had put another in (didn't buy a new one-- it was holiday). It did this exact thing to me. The scary part is once, it was on the interstate going about 75 mph... didn't die but all gauges went to nothing. It turned out that the battery I was using didn't have enough cold cranking amps and was pulling down the alternator too much so the computer shut it down. The one time it didn't... it was because the RPH's were too high. Try checking the battery and alternator... make sure you have the right battery and have an alternator shop test your alternator if the battery is good.
