Question about 2003 Dodge Grand Caravan AWD
I have a 2003 Dodge Caravan with a 3.3L it wont start or even turn over. Run test on electrical system found ignition signal to relay found power supply to the relay and ground to the relay. When I jumped the power to the starter circuit on relay starter would not engage. tested underneath the hood fuse box found no power coming out of the fuse box to starter unplugged the connecter from under the fuse box applied power to the yellow and gray starter wire starter engaged I replaced the under the hood power management module fuse box vehicle started up fine ran fine no lights no codes no nothing turn vehicle off let it sit for two hours start vehicle up backed out of drive way vehicle killed started would not engage. My question is this they have a silver box that plugs into the front of the power management fuse box relay is this box a starter relay module? I am having a starter engagement problem not a running problem.
My 2003 dodge caravan would not start after driving about 1/2 hour. I stopped for coffee and when got back in to start it started I switched gears and it stalled. I tried to start again switched gears then it started but only for 2 sec. No clicking, no cranking sound just would not start but battery functions were great. Spent 2 days with a mechanic who could not resolve so sent to Dodge. After a day of putting wires back and checking out the problem they said it was the computer. Said that it was bad and could be replaced at no charge due to malfunction. Yes, it worked fine afterwards no more problems. They also said that some of the computers are found to be defective like this one so I hope this helps you in the right choice to have the dealer check it out if you are unable to get a computer reading and there is no obvious short in the system. Free sounded very good but as you know there is no such thing as really free as they got me for other things $350 worth. ouch!

I think when you replace a new or used ECM (electronic control module) you have to reprogram it otherwise the the engine won't run

Yes they do but I would rather think you have a bad battery cabe connection to the system, sometimes the battery cable corrudes and you can't see it try replacing the cable ends and the connector ends espically if they are by the battery.

SOURCE: Water pump Dodge Caravan 3L
Go to any Napa, Autozone,or web info for diagram, as for step by step, here goes. lift right side of van and remove tire and splash shield, drain antifreeze, you need a floor jack to move the front of engine up and down during the process, remove right mount, engine plate, belts, tensioner, pulleys, remove engine timing covers, and expose the timing belt, set the timing to marks as indicated by diagram, remove belt, and remove the pump, while your in there,good idea to cange cams and crank seals. and timing belt. GOD LUCK. RDJRP.
