Stalled. HELP
 

Ok I went to deposit my pay check so I went out to lunch but on my way back I was at a longer stop light "and my fuel isnt low just putting it out there" but while i was at the stop light my 98 ram 2500 24 valve with the NV4500 5 speed manual stalled and restarted by itself in less then 5 seconds and my check engine light came on. what could this be

Did it completely shut off? Was te truck rolling in gear?

Yes it completely shut off and turned itself back on in about 5 seconds or less and no I wasnt rolling the clutch was completely pressed an the brakes compressed and it stalled out for a second or 2 an started back up without me doing anything. then the check engine light came on then a couple hours later the check engine light went off but I dont think it will stick. :argh: any ideas?

Crank sensor I would say:c:

Put a scanner on it. And it does sound like it could be crank sensor

took it to school had my teacher run for codes. Code: P1689. No communication between ECM and Injection Pump :argh: and apparently it shut off because connection between the 2 was lost for more then 3 seconds but apparently it found the connection again an started itself. last time I was told my mechanic told me about 1300 for new ECM and I'm looking a 1300 next month because the guy I bought the truck from a "professional" mechanic took the spacers off the injector lines and apparently when he put lines back on he didn't use the spacers he wrapped them in electrical tape and 2 are leaking the other 4 aren't but they aren't reusable so another 1300 :ouch: :s:

I wouldnt buy a new one. You can have yours rebuilt and save some money. I had my PCM rebuilt and it has worked great. Ill look and see if I have the name of the company. I found it. Solo Auto Electronics. I had found another one that was Dodge PCM or something and after some digging through bad reviews, found that one company was using 6 or 7 different website names, DodgePCM being one of them. They were all part of autocomputerexchange.com or .net or something. Solo repaired my PCM for 300 and I have a 12month warranty free. A ECM repair would be more but alot less than 1300. If you purchased a new one from them it would have a lifetime warranty. Hope this helps. :c:

It's most likely the ip and not the ecm

Im having a brainfart and cant remember the name of the machine we used to isolate the PCM to verify it was bad. I know you could use the same machine to verify is the ECM was bad or the ip.

for the sake of my pocket I hope it isn't the ecm lol and I looked at the websites but I cant seem to find any ecm's for my truck just pcm and tcm. but the ecm I found was going for about 250 but would need a reflash to work on my motor,year, an transmission combo and I have no clue what these things cost to install lol
