I'm not following you. You say you replaced it and then you ask how hard is it to change it.

No its not difficult at all. You just have to loosen 3 (or 5 I cant remember) bolts on the power steering pump assembly, which also serves as the belt tensioner. Once you get the belt off, its like two bolts and a nut for the wire. Its a very easy fix. Then repeat in opposite direction for belt re-tensioning. If someone could confirm which bolts to loosen on the PS pump, that would be excellent.

For the injectors, I will STRONGLY suggest EVILXJ, I will send him a message pointing him to this thread. I got his injectors. I have an 88 with 218K and it runs a heck of a lot better with the new 703 injectors, plus the price is great.

Ok so I replaced the alternator last night. It started this morning, but after leaving it for 8 hrs it wouldn't start. I had to jump it. Is it possible the battery can't hold a charge?

This is possible. You didn't leave anything on? Also how are your fuses? When I checked on my Jeep a while ago about half of mine were completely corroded and fallen apart (leaking clutch fluid and water). Turns out there is one that allows the alternator to charge. Definitely look at this too.

Just a thought..After you replaced the alternator are you sure it was charging properly? With a new battery and a bad alternator you can still start up and drive a long ways...It`s rare but sometimes the fusible links in the alternator wires can go bad.
