The symptoms you describe indicate a loss of fuel pressure or volume IMHO. I believe most Chrysler products rely on the oil pressure sending unit to power the fuel pump relay which keeps the pump running after starting the engine... a safety guard in case of an accident which would shut off the pump if the engine isn't running after an accident. There are tests which can be run to determine which is at fault, WHEN THE PROBLEM OCCURS. That being said, I'd replace Both the Oil pressure sending unit, AND the Fuel Pump relay, about $50.00 for parts. Note: Older Vans had the relay built into the ECM (Computer) and the whole thing needed to be replaced...expensive! Check with your parts supplier for listings on both parts. If the problem persists you have a bad fuel pump..."New" doesn't always mean "Good"! Good luck!

Well, yes and no. Some Chrysler products are difficult to make "talk" but there are ways if you have the right equipment and knowledge to use it. Very few shops have have both...WE do. Anyway, from what you said and describe at this point, I'd have to say you're experiencing a cam sensor, crank sensor or both failure when the engine reaches operating temperature on the warmest side. Here's how to do a simple test: Take a bottle of ice water with you on a test drive and when it (the car) quits douse the sensors one at a time and bingo! If it starts and runs normally you"ve found the problem. We've learned the hard way to replace both, even if only one is bad. If you need more you can e-mail me from our website www.goldenruleauto.com Bob

Replying to: vade2x2 (Jul 09, 2008 12:35 pm) Okay, having a 3.0 liter engine means that you have the Mitsusquishy engine, not the best of the three V6s available for the minivans. The good news is that the lower end of the engine (i.e. the block, crank, pistons and rings) are pretty robust, however, the upper end is highly suspect. That you have no compression on the #5 cylinder means to me that there is a very high likelihood that you need to have the heads reconditioned. Unless you do the work yourself, you’re probably looking at well over $1,000 for the job. Sorry to be the bearer of the bad news. Best Regards, Shipo

I want to start out by thanking everyone for all of the great commentary and advice for questions already posed. PLEASE HELP ME!! Anyway, I have a 3.3 6 cyl. that suddenly began knocking and sputtering last week after getting a tank of NOCO gas here in Buffalo. Heavy wet carbon shooting out of tailpipe leaving deposits on driveway. Loses power as I step on the gas and starts smoking heavily out of exhaust at 4k rpms in park gear. My buddy at Midas said no diagnostic code was popping up, and since then no engine light has come on. Took it to a local Dodge dealer who said it was running lean. They drained the tank, flashed the computer for some sort of combustion reset and sent me on my way 300.00 lighter. Nothing has changed and losing more power now as I push on gas. Any ideas?? Thanks, Mark
