Hi
i have a 98 grand caravan it stopped firing as i was driving it.
It was if i shut the key off
I replaced the crank sensor and tried my computer and coil in another van it ran perfectly.
i put those back in my van still no fire
I've checked all the fuses and haven't found any bad wiring.
any idea if it could be the cam sensor?
thanks

 

It sounds like you’re trying to diagnose a no spark issue - is that right or am I misunderstanding your post? Have you verified fuel pressure and injector operation?

1) Pull the codes and don’t replace any more parts until you do.
2) Don’t assume a code for a specific component means that component needs replaced - part of diagnosis is verifying the wiring is intact as well as good connections between the component and PCM.
3) If no codes are stored, start by verifying all power and ground feeds to the PCM using a test light - any circuit that glows dimly in relation to the others indicates a current flow problem (open/high resistance.)
