93 Ex XLT wont start after PS pump replace
It is a bit of a long story, but about 3 weeks ago my car stopped while driving home. Turned the key, nothing. Pushed into a nearby parking lot and opened the hood. The power steering pump reservoir was ajar and ps fluid was everywhere. I had it towed home and did not have time to work on it until this week. I replaced the pump and hoses, and while trying to bleed the system, I still could not start it. It actually rotates now, but will not turn over. I managed to bleed some of the system, but quit due to darkness. I would like some advice on how to start it; is it just from sitting for 3 weeks? The battery is fine. Thanks in advance.

I am a little confused by the terminology you used
"It actually rotates now, but will not turn over. "
If by that you mean that the engine cranks over but will not start, then I would suggest you rotate the key 2-3 times from off to on and listen for the sound of the fuel pump starting up. It should run for 1-2 seconds on each power up . If not running, and since it was towed, start by checking if the inertia switch got tripped. Inertia switch is in the cabin, above the transmission hump on the firewall. Peel back the top edge of the carpet and it should be visible. Look for a button you can depress and press it to lock it in. Then recheck for the fuel pump sound.

If you don't hear the pump running, and it's not the inertia switch, then check the fuel pump relay located on passenger side fender under the power distribution box. PS pump should have no impact on the truck starting.

Thanks for your responses!
I checked the fuel pump and inertia switch, nothing wrong there. So I decided to crank the engine for the heck of it and on the second time (for about 3-4 seconds), low and behold, it started. I suppose the Explorer gods were smiling upon me today. Now about bleeding the system. Any tips for completing the procedure correctly? Specifics would be appreciated (for my good as well as those reading this thread who would like to know as well).
Thanks again.

Dump some fluid in, start the engine, and turn the steering wheel back and forth, lock to lock, a couple of times. For extra credit, do this with no weight on the front wheels.
Steering gear is double acting, with hydraulic pressure on both sides (to turn in both directions) so no special effort is needed to bleed the system. Contrast this with hydraulic brakes and clutches, which are single-acting "dead end" cylinders, and take some effort to get the air out.
