1990 2.5L caravan stalled .First post.please help!

[sportedge]

My 1990 2.5L caravan stalled on the highway.It just stopped! The ignition was on of course so i had the ignition light on in the dash but no check engine light .Towed in. What i think is the asd relay was clicking on and off very fast.Fuel was filling the throttle body up to the neck,and the fire is very weak.
I replaced the computer,the coil ,the hall effect module and the asd relay(with a regular auto.relay i had in stock). Now sometimes gas will fill the throttle body ,depending if the ignition key is on while i disconnect/reconnect the asd relay,and the fire remains to weak to power up the engine.Cranks ok but will not start.Now with the new computer,the check engine light is on when the ignition key is on ,but impossible to get any codes when you cycle the key switch .This has become an obsession ,i'm loosing sleep over this. Please someone help! Oh! should i mention that this is the fourth time i replaced the head on that engine! Never had any problems,but this incident happened two weeks after the last head replacement.

I'm not very familiar with your Caravan (saw this thread on the Engineering/Technical forum) but there are quite a few issues on some other Dodges with various wire harnesses corroding. Since you mention that you measure battery voltage with very little current, that sounds a lot like a corroded connection.

Sounds like you need a wiring diagram to start tracing. You might be able to find the diagram from Autozone's Repair Information service or from one of the Caravan/Voyager experts in this forum.
