#25 of 32 2000 Dodge Caravan fuel issue? by kosmo5 Oct 26, 2009 (6:58 am)
The fuel pump went out and it was replaced along with the fuel filter. The van ran pretty good for about a week or so and then it started chugging sometimes like it was going to run out of gas. Then when I would press on the gas enough to make the transmission shift down, the rpm's would raise but the van wouldn't go any faster. It also now has a rough idle and the idle speed appears to be high. Has anyone had this problem or knows what a possible solution might be? Thanks.

Replying to: jerry69 (Jun 11, 2009 12:20 pm) I experienced this exact same thing and it was the oil pressure switch. Easy to replace and it it located on the side of the oil filter.

Replying to: kosmo5 (Oct 26, 2009 6:58 am) I would first test the fuel pressure in order to rule out fuel supply; there should be a fitting on the fuel injector rail, similar to that of a valve stem on a tire, to which a pressure gauge can be connected.

Replying to: xwesx (Oct 26, 2009 8:34 am) What should the pressure be? Could it be the fuel pump is bad? Replies to this message: xwesx (Oct 26, 2009 11:33 am) kosmo5 (Oct 26, 2009 11:46 am) kosmo5 (Oct 30, 2009 6:18 am) xwesx (Oct 30, 2009 10:16 am)

Replying to: kosmo5 (Oct 26, 2009 9:54 am) I cannot recall; I want to say it is something like 40psi. It could be a continuing problem with the pump, but it could also be something that is restricting flow (the conditions you described are high-demand situations for fuel). You would need to observe the fuel pressure under varying engine speeds and loads. In normal operation, the pressure should be constant.

Replying to: xwesx (Oct 26, 2009 11:33 am) Thanks for the advice, I will give it a try.

Replying to: xwesx (Oct 26, 2009 11:33 am) Could this also be an issue with the catalytic converter? Is there a way to test this to see if it is clogged? Replies to this message: xwesx (Oct 30, 2009 10:16 am)

Replying to: kosmo5 (Oct 30, 2009 6:18 am) It's possible - anything affected by flow volume could be the source: air intake, spark plug wires, exhaust, fuel. Air intake and spark plug wires are pretty easy to test (take a look at your air filter and check resistance in the wires w/ ohmmeter), but I don't know about the exhaust.
