93 GMC Jimmy won't start

[Bad_Brad]

First, I don't know much about my S10 GMC Jimmy or vehicles for that matter so please try to bare with me as I try to explain the problem.

Here are links to my 2 previous threads about my car in the past month.
The first one is about a parasitic draw from lights on my rear-view mirror
The second one is about a belt (serpentine belt?) that was shredded

Today, my Jimmy **almost** started. It would get close, but just couldn't make it.

Yet, recently (the past several months) I have had several things looked at, replaced, and checked and none of them have brought my car back to starting normally.

The first thing (this is detailed in the first thread listed above) was that my car had a parasitic draw coming from the rear-view mirror that would drain my battery. We stopped the draw and it helped my car start without a jump.
We next had to replace a blown belt (serpentine belt?) and the alternator (this is detailed in the second thread above) This still didn't bring my car back to starting normally.

The mechanics that changed the Alternator and the belt looked at the fuel pump and said that it was good.

This is just some side-info about my car that might come in handy. I got a new fuel pump over a year ago. Then, around last September I had the heater coil replaced because it cracked and leaked antifreeze into the car.

With all this info and my limited knowledge and supplies to fix the car, I really need help to find what is wrong before my parents go berserk and buy a new car.
