rebuilt dd60, ecm need help

sorry i've been away, the number should be a 5, as that was what came out on 05's, but they put in a rebuilt engine. we looked on it and cannot see any number, but we can't get to all of it, the other side of it could have it, but we can't get to it. we don't know if they kept the original one to the truck or if a different one came with the rebuilt engine.

 

well to update, we are sitting around getting no where fast. The shop where we work is not interested in even looking or try to diagnose our problem. we can't drive anywhere. as the truck stalls out as soon as it warms up. we were given advice to check our batteries which we did, and one was bad so we replaced all four, cause they were all old. that didn't help, went to minot and bought 2 sensors, the techs there were very reserved in talking to us, but did say that only water and oil sensors shut a truck down. the coolant level sensor was replaced going about 3 weeks ago, so we bought coolant temp sensor, put it on today, did not help, tried to put on oil pressure sensor but it looks complicated to get to, and got dark out, will try later today after daylight comes to get it on. yes we know we are throwing parts at it. but freightliner in minot cannot get us in until feb 7 and that will include a tow bill. some say that is like 2000 bucks. we need to work. everyday that goes by is costing us. anyone know a mechanic who can come to us? lol huh, I know thats a joke. we kinda think its related to the ecm or grounding wiring, or harness. but we arent mechanic's. or maybe related to fuel intake, air in it or voltage in ecm sensors etc. Like I said we aren't mechanics and don't have the diagnostick tools to find out these things. Saying my prayers and hope we get oil pressure sensor on and it works, if hubby can get it on. Thanks to everyone for your help and ideas. Thats a lot more than any of these mechanic's have had.

 

update, got a mechanic to put oil pressure sensor in yesterday, he also found a ground on battery that was corroded, cleaned connections. It looked like it was healed, could rev up to 2200 rpm, but when we took it out on road it derated again with check engine light coming on then letting off it went off. then we parked it in just a few it stalled out. told mechanic, he now thinks it may well be the ecm harness, or a ground, told him about ground to ignition, he was like "could be". He does not have the diagnostic tools here to check it all, so it looks like we gotta wait for the feb 6 appt with freightliner, and the tow into there. we are s--t outta luck for now.

 

update, well we can get the truck to idle without stalling out now. Today we actually drove it to Minot to freightliner. We could get it up to 50/55 mph, but on hills it would get down to 35, stalled out once on the way over. can't take going over 1200 rpms without wanting to drop down again. They will get to it Monday morning, sure hope they can figure this one out, told them about your ideas and asked them to read this thread to see what its been doing and what your ideas are. will let u all know what we find out, when we find out. thanks for your help
