Hey all,
Any advice would be much appreciated if you have any suggestions.
We made a mistake on our 1999 270 DA 7.4 MPI (single engine) & the battery selector was accidentally switched to "off" while running. Seems to have been a big mistake & the selector & manual read never to do this. Kind of obvious now but i am trying to determine what needs replaced.
Upon switching the battery selector it immediately killed the engine. From what i've read & discussed, i've replaced the alternator & checked the fuses & relays. New alternator, fuses, & relays all seem to be in order but when key switch is turned on there is no "beep" & the fuel pump does not engage (fuel pressure is at zero & relay does not pop). Moved relay to different location & relay seems to pop in different location, so i assume relay is okay.
Any advice? Would this have toasted the ECM & how can i tell? Any other items i am missing & can check?
Any help would be much appreciated.
Thanks,
Brandon
