I have a 2004 Wrangler w/ 2.4L motor. I lost a rod bearing in the motor, so I pulled it, put in a new crank and rod. Replaced the piston rings. Head and valves looked good, so I didn't mess with them. Put a new timing belt and plugs in. I didn't replace the plug wires.
Cleaned everything well, put it back together and in. It will sputter every so often, but won't start.
I pulled the front end apart and re-checked the valve timing, and it's right (as far as I can tell from my Haynes manual).
The plugs are getting wet. I've verified that all 4 cylinders have good compression (my compression tester isn't long enough, so I can't give you an exact reading).
Checking the plugs, each one seems to spark when the appropriate cylinder is on compression, BUT, they only seem to spark every 3 or 4 compression cycles.
Where should I start checking? My Haynes manual is USELESS (I even had to look up the Crank and cylinder specs online). I am going to buy new plug wires, but each cylinder acts the same (firing every 3 or 4 compressions). Is there a sensor I should test (Crank Position or the one on the exhaust cam) and if so can you tell me how? Or is something wrong with coil pack? Can I test the inputs to the pack?
I did clean the grease and crap off the coil pack with gas and a brush during the rebuild.
Thanks in advance.
