    I think it will be a lot of Farting around to change to the big relay! ! I would buy one more relay and start by changing it out one at a time with the relays in that group. tryng it for a couple of days at a time till you have tried going thru the all of them! Also Is it possible you have a bad ignition switch?

    Never thought about switch ..it goes days no problem then shut down and fires right back up no issues after that ..but will look into that

  3. Ok I replaced the relay and didn't have a problem for a little while but it shuts down every now and then..I check the railway when it shut down and its warm not hot just different from the other 3 so I'm thinking of putting in a 100amp relay and replacing the 70amp or even just putting the solenoid like other models have ..what's your thoughts..thanks guys

  4. 2001 rd just did inframe less then 1000 miles on it..someone replaced the original engine with a 99 e7 427 same engine from factory just different year put new vecm had mack reprogram it to specs truck runs fine then will shut down red x comes on heater blower everything shuts down wait a few minutes starts right back up run 15 min or less shut down no codes what so ever..please help I'm so deep in this truck and not able to run it ..first did it last week ran bout 12hrs no problem then started this

    Thanks in advance 

  5. Ok guys put the vecm my buddy has in truck runs great .does the vecm store codes from the previous truck..soon as I started the truck it has 3 codes 1/3 5/5 7/ 2 ..the lighting volt seems to stay on ..can I have the codes cleared and hopefully the light goes out ..drove it about 80 miles home no problem..thank In advance 

  6. Mackpro I've found a  company that has a ecm same numbers same engine would I still need a reflash or it would be hit or miss..also what's the average cost of a reflash on the ecm..
