The back story on this is, I bought 3 Liberties, an 04 and 2 03's all with 3.7L engines. One was water damaged but ran, one hit a deer and had front end damage and the third had a missing fender flare, broken mirror and a seized engine. The 04 is my first project. I stripped the engine, transmission, and t-case and inspected it, no real issues except of course for the siezed engine, so I replaced the engine and stuck the drive train back in. Not all the wiring matched up but that was easy enough to fix by swapping a couple of sensors couldn't fix. Now everything is hooked up right but she won't start, there are no obd codes triggered and I can't seem to find any issues. It turns over fine but I can hear what sounds like somthing big dropping in water and sometimes it quietly backfires. It is getting fuel and spark but does not want to fire. Any auggestions?
