I was on my way to work this morning as right as I"m backing into my spot the '89 carbbed 4.2 died out on me. I tried to start it back up and it started for a couple seconds and stalled back out. Kept trying and I finally for it started again, revved it up a little bit and it did rev, oil pressure looked good, and battery gauge was a little bit to the left of TDC. It then stalled out again and when I went to start it all I get is on "click". I'm thinking the alternator is gone, but would like some input. The guy I got it off put a new starter on it not too long ago, maybe 2 years at most, so I dont really think its the starter. Any other possibilities?
