I have a 2002 jeep liberty that the engine went bad in. I was going to overhaul it but found out the block was no good. I got a bottom end ( block, crank and pistons ) from a salvage yard and overhauled it. I got it all back together with the original heads and all the other things from the original engine, crank sensor, cam sensor, new coil packs,new spark plugs,,,,,, everything is brand new. But now I have no spark. What could my problem be ?
