What happen when pcm starts to go bad - 2003 Dodge Caravan

Not sure exactly, but I just replaced mine about 5 days ago. Mine was driving along fine and suddenly started sputtering and stalling out. Would only go about 30mph, wouldnt shift out of 1st. It was blowing black smoke out the exhaust. I had a mechanic diagnose it as being a bad computer. After I replaced it, I still had the same problems. After further research I discovered that a common problem in the 2003 caravans is the fuel rail harness. (connects the injectors to the main wiring harness) Right where the two harnesses connect, the wires are right above the intake manifold. The wires melt and short out. Hope this helps.

Fuel realy does not pickup in the keyswitch "Start-Run" position; and the starter relay will not pick up in the keyswitch "Start" position. All other controls and accessories seem to work just fine (radio, lights, remote lock, headlights go off in the start position, etc). I suspect a PCM problem. The dwgs are pretty bad and hard to follow and hard to cross reference from sheet-to-sheet. The vehicle is a 2003 Dodge Caravan V6 3.3L. All the wiring harnesses look good. No codes. Problem wa

Mine is doing this what is it? have a 2002 dodge caravan with a flex fuel 3.3l. When it is first started it floods out so badly that it almost will not run. you have to hold the rpms at about 3000 just to keep it running. According to a matco determinator scanner it is stuck on 85% ethanol. I have never used ethanol. So far i have replaced the plugs and wires, coolant temp sensor, cam sensor, crank sensor, ignition coils/module, pcm, and tcm. I have even pulled the tranny to inspect the flexpl

The temperature, speed, and gas guages arent working on my 2000 Dodge Caravan 4 cylinder. The milage only lights up for a few seconds then goes out. My Dash lights work though. Also when this happens my rear wipers don't work and I cant change the temp or position of air flow on my heater. My fuses seem fine. This problem would happen for about 15-30 min before then everything would start working again. Recently it happened and didn't start working again.

G'day mate it would seem that the fuses though on inspection are fine they may be not so good if removed for inspection also remember that if the fuses are dirty that moisture will carry a voltage to earth on a dirty damp circut. also there should b ... 2000 Dodge Caravan

2003 Dodge Neon Sxt standard transmission runs great but recently has started suddenly trying to die. I will be cruising in 5th gear and feel a sudden jolt and look down to see my gauges all fall to 0 before returning to where they were and I'm cruising again. Sometimes this will happen when I am in neutral and the car will die but starts back up no problem and runs fine. It doesn't happen often but it seems to be progressing. It almost seems like some kind of electrical short to me. The check e

2000 dodge caravan will start and most of the time will and nothing happens at all when i turn the key . i try 3 or 4 times an it will start this happens about once a week

I have a 2001 Grand Caravan Sport. A tuneup was just completed and the coolant system pressure check tested good. Every time the engine is turned off a swoosh or swish/winding down noise happens in the engine area. The noise does not happen on start up or while running. I am wondering if I have a bad bearing or something else. How can I pinpoint which part is bad. Any guidance is appreciated

Hello,\012\012If the noise get louder on some certain speeds then it is a bad bearing. You are describing the noise as swish/ winding which makes me think that most likely it is a wheel bearing, try rotating the tires also.\012\012Thanks ... 2001 Dodge Grand Caravan

I have a 1996 dodge caravan (3.3L) that won,t start.I had diagnostic test done and it showed a bad crankshaft sensor.I replaced it and it still did'nt start so i went ahead and replaced the cam sensor and it still won't start what else could it be since the diagnostic test only showed the crankshaft sensor bad.

Typically, the on board computer monitors the crankshaft for rotation and the cam shaft for rotation, and fires the spark plug accordingly. There may also be a sensor for top dead center for cylinder number one. If you have a broken, or slipped timi ... Dodge Caravan

I own a 2001 Dodge Grand Caravan..3 days ago it started acting up. I pulled out of a driveway and started somewhat slowly up a hill and the van shut off. I was able to start it, get it up the hill but when I was going downhill it cut off again. I started it and it started fine but when I would press the gas to go forward it would cut off. I could go backwards fine. I finally got it to go forwardbut then when I am slowling letting off the gas it sputters real bad. Now I can get it to start but it

Starting Problem I have a 2000 Dodge caravan sport. Several months ago I started having problems starting the vehicle. When i turn the key, nothing happens, no clicking. the dash lights do come on. Usually starts after several attempts and runs fine once running. There have been 2 occasions when it would not start. Started immediately when I hooked up the battery charger. I have had the alternator tested and replaced the battery. Was fine for a month after replacing the battery but then problem

Probably a bad starter as well. A good battery can make a marginal starter work, but over time the battery will be weakened by the drain of the starter or the starter will get worse.Remove the starter and take it to your local parts store ... 2000 Dodge Caravan

I own a 1997 dodge ram 3500 turbo diesel. I was having intermittent problems starting it and tested the starter by shorting out the solenoid and determined that the starter was bad (I put a screwdriver between the two lugs and when a second person turned the key nothing happened). So I replaced the starter (with a starter from auto zone). The truck started fine for couple days and now will not start again. It turns over strong (two new batteries) but will not start. Although, It did start

No it doesn't mean that you have a problem.When you cross the lugs with a screw driver no matter whether you have the key on or not it will still engage the starter.The reason being that you have the hot wire from the battery going to on ... 2001 Dodge Ram 2500 Truck

1997 Dodge Caravan 3.3 shuts off for no reason, but if your going fast enough 55 mph it starts up as fast as it went off. When that happens the cruise will not work and the speedomter doesn't work, unless you stop the car, turn it off and back on again. Then I get all contolls working. Sometime it won't start at all, maybe a month goes by and I try it and it starts right up. If I check the codes sometimes they are there, sometimes everything is erased and it erases the start cycles. I've had it

I have a dodge mini caravan 2000. When i start the car the key wont start the engine. This seems only to happen when its really cold out side. It takes quite a few tries to get it to start.

What this sounds like is a clogged fuel filter and is an easy fix. The next time it is cold and you go to crank it, try turning the key to the ON position w/out cranking it and turning it off a few times. This will pressurize the fuel system. If it w ... 2000 Dodge Caravan

I have a 2002 Dodge Durango & my PCM needs to be replaced as the P0601 code poped on my dash. Although the PCM needs to be replaced the car still ran great, maybe suffered a little gas mileage but still ran great. Recently the battery went bad so I replaced it, now the new battery died & when I had the car jumped it won't stay on. It turns over & starts but won't stay on & stalls. My first thought is it's the alternator but it was tested & is fine. Question, can the PCM kill a battery or burn ou

You may be able to get it replaced under warranty if it's less than 80,000 miles on the odometer.To answer your other question, it all depends on how the PCM was blown. It may have shorted out just enough to cause a constant draw in the ... 2002 Dodge Durango

I have a 2001 Dodge Caravan Sport 3.3. Started running bad recently and check engine light is on. I had the code checked and it pointed to #5 fuel injector. I replaced it, the TPS, The IAC, and noticed the main wiring harness on the back side of the engine was laying on the exhaust manifold and melted so I replaced it too. The van still runs bad and check engine light is on. I have disconnected the battery for days at a time and still runs bad. I have also checked all the plugs and wires and the

My 1993 dodge caravan is having a strange issue. One day when I was driving on the highway doing around 60 MPH i noticed that it was not accelerating and the more I pushed on the gas the more the speed decreased. I pulled over to the side and my car died completely. I tried turning the engine over and it shook extremely bad for a few seconds so I turned the engine off, waiting a few minutes and tried starting it again. This time the engine screached. I waiting about 30 minutes and started it ag

The a/c and air recirculator buttons continue to flash on my 1997 dodge grand caravan at the start up of the vehicle, and continue to do so for about 20-25min then they stop - this happens every time you start the vehicle. I've had 2 answers (which contradicted each other, but I tried them both) where I should depress the top/bottom of the 3 leftmost buttons to calibrate the system(one post says on cold, the other says on hot), and this seems to work, but at the end, the a/c and air recirc. con
