Ill see if I can explain better, yesterday both times I started after a 4-8 hour engine off period it would start run real bad(smoke, romp, lotsa black smoke for 30-60 seconds)than run perfect. Turn off for another 90 minutes after driving 100 miles tried to start again and was romping. So I turned off cleaned a closed egr and put back together tried to start after that and puffed black smoke would try to start and puff smoke until all it did was just turn over. I towed to dealer last night and am waiting for a call. I hope it would be a simple as egr but mine was closed and don't see a closed egr being the problem also tried starting with the egr disconnected. Thanks
Well it seems I have a 1000 lbs of oil injector psi but 0nly 30 volts at the injector during crank need 48 I guess. Does have 48 when not cranking or manual cycle? Recently had head gaskets replaced think maybe chaffed wire? Has had a ficm replaced while back and also I think the wiring harness update. Dealer ran out of time to know for sure but this is what he knows so far. Thanks
