I have a 1992 Dodge Ram Van 318 ci. It died while driving. No ignition, no check engine light, starter won't crank. Battery is good, cleaned posts, changed ignition switch. Still nothing, any ideas?

Be sure to check all Ground connections , and shutdown relay.

This procedure usually works:
·Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

I had an intermittent starting problem and then a no start situation in a 1991 with the same engine. Changed the pickup inside the distributor. Less than $30.00.

There is a starter solenoid between the battery and the starter. Check that to see if it has gone bad. It will not set a light. you can jumper from the power lead to the starter post to see if it engages. Be sure you are in neutral if this is a standard shift because you will be bypassing the neutral switch. The solenoid is on the firewall or well well depending on your options configuration.

Hope this helps
