Was driving 70mph and the truck died. Started again on the side of the road and died a few minutes later, would not start again.
Will not start, No spark. Poured a little gas in the throttle body and turned the key: nothing.
I have searched and searched for things wrong with this problem and have checked them all and they are all good. I am leaning towards a bad computer, but I am not one to buy a part without KNOWING that it is causing the problem. My question is this:
Is there a definitive way to tell that the computer is bad using an ohm meter?
Things I have checked: ASD relay (good), ohmed out the crank and camshaft position sensors (both are good), put a spark light on the ignition module (got a light), checked the O2 sensor wiring(No faults), good voltage on the battery (13vdc).
Did a general tune up about 10 months ago when I had another no start problem, it ended up being a bad camshaft sensor but in the process I changed plugs, wires, cap, distributor rotor, ignition module and crankshaft pos sensor.
I don't think there is any correlation but this happened the day after I fixed a cracked door latch mechanism, after the repair the dome lights will not turn off after the door is closed now (light switch ohms good), no fuses blown.
It has been two weeks and I can't figure it out. I want the broke thing out of my driveway! lol
Awesome! I'm glad that I have without a doubt located the problem... Can anyone give me an OEM part number? The one I changed was an aftermarket crap one and need to get the right one... I found a Delphi one at advance auto and need to know if that is the right one.
i've been looking around for a replacement for mine. Mopar overstock carries the sensor but I dont think they are genuine Mopar. Additionally, they make you give your information before they give you shipping costs, so I opt out.
The last one i bought 3 years from NAPA was a Sorenson and i havent had any trouble with it.
Dealer will probably tell you they are on nationwide back order.
