Had damn fuel return line leak at the clamp on passenger side head. didn't have time to wait for new line so I removed cut and sleeved fuel line with hi pressure hose until new one comes in. In process I unplugged injector/glow plug harness passenger side for easier access. Upon putting together in rush I forgot to plug harness in and tried starting truck...no start figured was just air in lines so cranked for a while no joy....I then remembered harness plugged it in it started. Let idle for 10 mins or so looking for leaks. Got in for test drive max boost was 1 psi fuel pressure at 62 psi. Figured connector wasn't right so pulled and ohm out injectors at valve cover all 2.8 to 3.1 so reconnected harness and split at drivers side valve cover main idm harness juncrion....all driver and passenger side ohm within spec highest at 3.2 ohm. Started runs like ass....driver side exhaust manifold hot to touch passenger side was cold after 5 mins.... Could i have possibly burnt up IDM by trying to start while unplugged????
