After replacing my valve cover gasket, oil pan gasket, oil filter adapter o-ring and "distributor" mount gasket, it won't start. It's a 2000 4.0 distributorless ignition, I believe they call what used to be the distributor the oil pump drive with the CMP on top of it. I marked the position of the pump drive to the CMP. It only goes one of two ways because of the flat-head shaped bottom and the keyway by the cam, meaning that you're either perfect, or 180* out of timing. So it was time to fire her up and it just cranked and cranked and wouldn't fire. So I thought maybe I made a mistake somewhere along the way and put the drive back in 180* out. So I took it back out and turned it 180* and tried again. This time after some cranking it fired, shook a few times really hard, then died. Cranked some more and got it to run with my foot in the gas at about 2k rpm but it was still rough as hell and shaking like an earthquake and died shortly thereafter and set a cel. I read the code and it's p0352, "ignition coil #2 primary circuit". So now I'm baffled because I never took the CMP off of the pump drive so as long as I'm not 180* out from the pump drive to the cam gears it should be timed fine right? I never moved the jeep while the pump drive and CMP was out. Does the position of the CMP to the pump drive matter at all? I found this article which was very helpfull but didn't solve my problem.
