Hi, I had to do a motor swap on my car listed above. I bought a used motor from a same year cirrus. Motor is in but having problems. Motor will turn over but won't fire. My friend seems to think that the computer needs to be replaced. Any thoughts?

Good morning,

You need a spark, fuel pressure, and compression.

I attached some guides for you to follow. You need to make sure you have these systems working.

You need to hear the fuel pump run for 2 seconds when you turn on the key.

You need 140-160 pounds of compression for it to run.

You need to spark at the plugs when cranking.

Let me know the results.
