doest my 91 caravan have a ballast resister?

Question

I was on route driving in the rain when it first died.After 1 hour it started drove it 475 miles then it died 42 miles from home and has not started since. NO SPARK .
it has no spark i have changed coil, Checked wires from ECU to coil, they are good. Changed ECU, still nothing..Changed cam sencer,
changed crank sencer,Changed auto shutdown relay,changed map Now i'm out of idea's.
does it have a ballas resister ? ware at ?

3.3 it has no distribitor

Answer 1

<>Not sure about a "ballast resistor" (I think those are only in florescent lights?!), but try this: Take off the "distributor" cap off and crank the engine- does the rotor turn? If not, you broke the timing chain/belt and will NEVER get spark until you fix it.

Answer 2

There is NO ballast resistor in the ignition circuit. There is no need of it, as there are no ignition points to burn up. The ignition system functions much better with full charging voltage at the coil.
Have you checked the trouble codes?
Have you tested to see if there is power to the coil, and is there a pulse at the negative side of the coil?
Have you tested the distributor? You have pretty well replaced the entire engine management system.
How about DIAGNOSTICS?

…and scroll down below the chart that appears. Read and follow the instructions for retrieving the diagnostic trouble codes.
You must pay attention and not space off. You only get one chance at each code. If you think you missed something, or just want to make sure, turn the key off for > 30 seconds, and start over.
You replaced the ECM, and the codes that were stored in the original are now gone. But if there is an active code remaining, the new ECM will have stored it.
If you have already been here, there is something missing. Use your test light and volt meter to follow the circuits. If there is no pulse at the negative side of the coil, and the light stays on steady, the distributor has failed.

Chrysler stopped using ballast resistors when they changed over to fuel injection. Try retrieving the trouble codes from the ecu. Switch the ignition on and off five times quickly , then leave it on on the fifth turn. The check engine light will flash a series of 2 digit codes which should lead you in the right direction as to what is causing the problem. If it's the 2.5L,
I would also take the cap off and make sure the distributor is turning. It may be a broken timing belt. If it's either of the v6's, I would check the timing chain. On the 3.0 L, I would check the ignition module inside the distributor.
