I just got done rebuilding my 4.0L after 230,000 miles. Broke a piston and had the entire engine honed (.010 over) milled and completely done over and ground the crank .010 under.
The problem that I am having is I've gotten it all completely back together but I don't have spark at the plugs.
I've checked the coil and it tests good. 1.4 ohm reading on the 20M setting though the two poles on the plug and 12.1 ohm reading on the 200k setting on my multimeter. I've checked all the wiring (i think) to make sure there aren't any broken wires. And I verified that all the plug connectors are in good shape.
I've got all new wires, plugs, distributor cap and rotor. I've verified timing about 4 times.
The only thing that I can think of being bad would be the hall switch in the distributor, or the crank position sensor.
Any help on this would be greatly appreciated!!
