It must be something on your end because no other complaints have come in. Can you try it on a desk or laptop? Did you have this problem before?

Just jumping in here. You say you replaced the engine in your 1995 Wrangler with one out of a 1998 Wrangler, correct? Now you have a no start. Although those engines are based on the same block design, they are not the same engine internally. 1995 would have been the last year for the early version of the 2.5 4cylinder and the AMC designed computer controls for it. 1998 used a different control system with the timing and computer coding different. For a bolt in install in the 95 you can use the 91-95 engine.

You would need to change a lot to make it work because the modules are all linked. The PCM uses codes stored in the BCM for the security system and both are tied to the dash as well. So swapping one means you need to swap them all. It's one of the "fun" things with doing engine swaps these days. Especially Chrysler products because of all the times they have changed hands and control hardware. It becomes even more fun when they don't show the changes. When they built the new modular engines in 02 they changed things 4 different times but used the came basic engine, just made them incompatible. With Jeep it was worse for years because of all the different engines they used. You need to have a scorecard to track all the changes.

You are not the first to get caught by their trap. There were a number of shops that have gone through the same thing, and I don't know how many DIY folks as well. It's one of the reasons why I don't even try swaps unless it's an identical engine. Many times, I just order a crate engine and ship in the old one as a core. Less aggravation that way. Hope you don't lose much. Sorry the news isn't better.

You are welcome.
