Hello,
My wife has a 1998 TJ with the 2.5L and a 5 speed. The #4 piston sleeve broke apart so the motor started knocking pretty good so we bought a remanufactured long block to throw in. I just finished buttoning up the swap and the engine will crank, but won't fire. I know this will be like finding a needle in a haystack with the amount of work I did, but I can eliminate a few things I've checked so far:
I verified the fuel pump kicks on and I have fuel at the line (checked Schrader valve), pulled codes and nothing. So I'm under the assumption spark is my issue. I did realign the distributor with cylinder #1 at tdc, checked fuses/relays, visually inspected grounds, verified all connections are good with one exception. The previous owner apparently broke and removed the connector on the harness side for the crankshaft position sensor. I've moved the wires around trying different combinations with no luck.
I'm guessing it is either the crankshaft position sensor connector or a ground somewhere... Does anyone have any other ideas I could try? I do need to pick up a new electrical tester as my old one is shot so I'll be able to start testing circuits soon.
Thanks in advance!
