I have a 1991 wrangler with the factory 4.0. Recently I changed the rear main seal, oil pan gasket and distributor gasket. After I finished I have been unable to get the jeep to start. I can smell fuel on the plugs and hear the pump prime so I assume it is getting fuel. Additionally I pulled a plug to see if I was getting spark and it is. So fuel and spark but still no start.
I tested compression on the cold motor and starting with cylinder 1 got 90,90,80,85,105,80. Other than the 105 they don't seem too far apart. I checked distributor timing twice by finding tdc compression for cylinder one and it seems to be pretty much on. I also changed out the distributor to my old one but still no start. When I try to start it the battery meter is showing around 8 volts and the tach doesn't even hit 500 rpm so I tried to bump start it on the hill near our house but that also failed.
Any suggestions? I've been at this since last night and am at a total loss of ideas now.
