[QUOTE="NMartin, post: 1305421, member: 23759"] My truck is a 1997 2wd F350 7.3. E fuel, Baby Swamp injectors, cx racing intercooler, 6637 filter, hydra chip with custom tunes, hx cross over line, 4" exhaust, rebuilt turbo with 360° bearing and 7 fun billet wheel, heat wrapped up pipes and down pipe, IssPro gauges.....I know these things may not make a bit of difference but I wanted you to know everything. I blew a cooler boot just before the turbo with high boost a day or so before this started, if that can affect anything. First idm was the original one but had the 140v mod when it quit completely. Borrowed a friends idm and it fired right up. Got a 100v replacement and it fried immediately. Borrowed a 100v from a friend and it ran fine for 2 weeks. Bought a 100v & 140v so I could give his back and fried both immediately but it will run on them, just not firing on injectors 2 & 4. Note I've checked the alternator which is fine, installed a new Dorman uvch under the drivers side, tested all ohm resistance at the idm plug and they all read 2.8 ohms which is within tolerance, I believe. I'm now taking all ground wires loose and reinstalling them before I check ohms again.I'm at a loss, and scared to install another idm. Used the good borrowed one one last time for a buzz test, which showed the injector solenoids to be good, and started up the truck for a possible contribution test and I think I fried it too. It will again run but only in 6 injectors. I need help guys, badly. [/QUOTE]
