Just curious if you don't get spark at the coil but if u bypass it does that have to do with the crank sensor?? Also will the fuel pump not kick on if there is no spark?
Need help ASAP
Car was running fine Sat night and just died and now can't get it started there is no spark?

Back in those years of Chrysler products they had an issue with a common splice connection that fed power to the ignition coil, fuel injectors, alternator field circuit and a portion of the computer, that went bad.
This splice connection was a stamp-welded connection that fused (welded) a number of wires together and then just covered with tape for insulation. The tape wasn’t good enough and it would corrode; allowing portions of the welded wiring too break away.
With a test light connected to coil positive and the ground lead clipped onto a known good ground; turn the ignition on. The test light should light for a couple of seconds and then go off, just like the “prime cycle” of the fuel pump.
If this is not happening; the problem is likely this splice.
There is a chance that the problem is the auto shutdown (ASD) relay; I’ve only had to replace or repair connections at an ASD a few times. I’ve repaired the splice a number of times.
You’ll find the ASD on the left inner fender, along with the starter, fuel pump, AC, a cooling fan relays.
When you turn on the ignition the ASD & fuel pump relays should click on and then off, then turn back on, as you begin to crank the engine (prime cycle).
The ASD will likely have the same color wire leaving it that goes to the different components that it feeds power to.
I don’t have access to my wiring diagrams, right now but I think the wire is a blue or green wire (can’t remember); just have a look at the coil positive, injector & alternator field feeds, they all should be the same color?
The next trick is to find the splice because it is inside the wiring harness, along the left inner fender, close to the auto shutdown relay; somewhere between the battery and the fire wall.
Sorry I’m being a bit vague but I’m at my weekend trailer and don’t have access to my manuals.
