:furious:I've had this ranger for about 2 n a half years. I got this stupid little diode off ebay for 20$ and of course stupid me I tryed installing it where it said to, in the mass air flow sensor. When I relized it was making my engine run wierd I took it off and hooked the MAF back up and it seemed be running alright until the next day it lost oil pressure and shut down. I thought the engine had seized up because nothing would work at all. So after about a year and a half of sitting I went out to try to see if it would turn over and it did barely, so I went and bought a new battery and a new starter and it fired up. It definately was running ruff but there still was no oil pressure. So i have the oil pan hanging right now to look at the oil pump but i cant get it off. The chilton book I have for it says I have to take the engine out just to take it off but I was looking at it and I was thinking I might be able to just drop the front end. I also have a 4.0L engine out of a 92 explorer that I could buy and swap out with my 99 3.0L ranger and im wondering what it would take to do so. If anyone has any advise I would very much appreciate it.
