ECM PCM STARTER 2003 DODGE GRAND CARAVAN 3.3L V6 WONT START

[JamIe121981]

I think that I am having ECM issues as well. My problems started with a battery indicator sensor. I hooked up an analog tester and determined that the battery was good but noticed a spike in voltage from my alternator.You could also see the voltage spike affect the headIights as well as all my instruments acting crazy almost a rhythmic response. Faulty sensors pop up too. This only happen after the van is started and running for a few moments. Not immediatly upon starting. Any advice?

@dynoegg: When your car did not start while the failed ECM was still in, did you hear the starter relay click/activate when you turned the key to start position? The reason I'm asking is I believe the ECM pin 31 provides the grounding path to the starter relay pin 85. PCM provides the ground path if double start safety and neutral safety are satisfied. If correct and failed PCM is still connected, you should Not hear the starter relay click when you turn the key ignition? Can you confirm? Thx

@lowrideaz I wanted to keep the video a simple as possible and to my point. The process I found worked to prove that point. Which was to know if the wiring is fine and if the ECM was sending the start signal. I got continuity though out but no power on the starter line that the ECM sends when you turn the key. Relay clicked with old ECM as it should if the relay is good.

@lowrideaz ... ... My process may contain error if extended to apply to other things. Replacing my ECM fixed my problem ... thankfully cuz I was getting pissed at it lol.

I don't have my book near me to look at the pin & line path to confirm the ground path and how the relay fits in. I do know the ECM did not send the start signal to the starter when I turned the key.

@dynoegg Thanks for the prompt reply, I understand . My mother's caravan is experiencing intermittent starting problems where when happens, starter does not engage. That's why I'm digging into the details so I can help her troublshoot asap. Thanks for the video and I'm glad you were able to pinpoint your ECM and resolve your starting issue. Thanks.

I CAN'T HEAR YOU THROUGH THE "BEEPING" MUSIC!!! WHY?

[scooter12368]

Oh, by the way, the music was nice. It relaxed me enough to want to concentrate.

[scooter12368]

I thought the visuals and your communication enhanced video. I liked the still shots with the titles on the parts an pin connections.

What allowed you to eliminate the starter being bad. I understand you have continuity but the starter could have been bad. Right?

I have a 2002 Caravan and it has a starting issue but after many attempts it will start I have a question, were did you get the new pcm? I would like to go with a good company. This would be of great help. Thanks!

[dynoegg]

@trainsonthebrains I got it from autocomputerexchange

Thank you so much for making this video. I have been racking my brain about this for hours. you are awesome

[GalaXy808]

We have thesame van but 2007,Doesn't start I don't know if the starter? Or where is the problem and how look like the starter of 2007? Thank you help please...

wut song is this ???



[TheDogLover78]

I like your video. Where did you get the schematics with the pin numbers? Thanks

[dynoegg]

@TheDogLover78 ... Chilton Repair Manual , Good old faithful

I'm dealing with this issue on my Wife's van and this video has been a huge help. Thanks for the troubleshooting tips and the thorough details. Great job!

LOSE THE MUSIC. Very difficult to understand on computer speakers what you're saying. Overall, volume was too low through laptop speakers, and didn't have earphones, so this didn't help me, other than to locate certain parts.

[anjilbl0od]

yeah guitar has to go. I'm a musician myself, i just can't hear what you're saying guitar is so distracting, kind of depressing, makes me want to just hit my car with a hammer instead of fix it. I'm so pissed, i'm out of work because of this van.

[AdorableAdorna]

Just finding an ECM for our Dodge at this point would be nice. We discovered a ton of corrosion on ours, about a year ago. Tried to clean it up, but it's acting up again. I found a place that sold them, and was sure I bookmarked the site, but now my bookmarks are all dead.

[terrance3850245527]

I would like to say that this video was very helpful.But I do have to agree about the guitar being distracting.My van was running fine yesterday and this morning it wouldn't start.So as of right now it's still not fixed.I hope I can find someone to check my starter tomorrow so I don't have to waist money I don't have.

[vellrob]

Freakin Genius! These so-called quack a** ASE certified mechanics around my way didn't even do a continuity test!! I know when they lied to me, and they didn't even know I knew. I deal with computers daily and have been for over 15 years. They should've checked! Your video was very informative. Thanks a million.

We kept replacing the TPS, but something is burning it out. These quakes can't even tell me what common sense could. Thanks again man!

I have a 01 dodge caravan it just stalled after I got gas and now if it starts it run for about 3-4 seconds and stalls.. If you push the gas it will die instantly.. Anyone have any answers??

[dvanize]

my van done same thing, I have no power to striped wire when key is turned as i had my test light grounded to the battery and probe inserted into the yellow wire. The relay clicks as i turn ignition to on, is this the same problem you had?

[Hollrobb]

How much did the ECM cost you? My wife and i have a 2001 caravan and for a few months the check engone light was on but the van ran fine but after a few months the transmission wouldnt shift into high gear and after running a test on the van it read out 3 sets of error codes one of wich was the transmission control portion of the ECM. I did replace the speed semsors in hopes we could at least get it to shift into high again but that didnt fix it. So our next step is replace the ECM.

Thank you.

I thought you did a nice job, but next time leave the music out. Way too distracting and had to back up several times to hear what you were saying between guitar plucks. Keep it simple! Nice work
