Background: A couple weeks ago I went wheeling in some mud pits that I normally don’t go into. However, from the pressure from friends I went through. After this excursion, my Jeep ran fine. It did however kill the alternator, which I replaced.
Problem: But last week it wouldn’t start. The starter motor turns it over but it wont catch and fully start. I just put in the starter a couple weeks ago. At first I thought I might have gotten water into the intake because I had mud and oil on it (From a blown AT hose blow). Cleaned the K&N air filter and put it back on. Throttle body was clean. Then I tried disconnecting all the fittings and stuff that are in the engine bay. Also replaced the fuel filter and distributor cap. Then, yesterday, it started fine and ran until this morning. What is wrong? I’ve looked and found that it could be the CPS, MAP, or the IAC. Are there any tests that I can run on these to see if they are bad? Any other ideas? TIA
