Please help.

Alright heres the story. =]

I was on my way to school a few days ago and unfortunately my wonderful 98' Jimmy decides to just shut off.  Finally got it pulled over and figured maybee I ran it out of gas because i was running low so I got ahold of a friend and brought me a couple gas cans.  Put the gas in and it still wouldn't start. Said screw it and got a ride to school.  After school I went home and got the truck and towed it home.  I got it home and pushed it into the garage and I got to looking at it.  I could hear the fuel pump running but I figured I would try putting some gas in the intake to see if I could get it started.  Still wouldn't start.  So I pulled a plug and it looked fine, put it back into the plug wire and did a spark test.  My spark seemed really weak so I figured distributor cap? Took off the cap and rotor and come to find out it looked pretty bad.  So I went to the local autozone and picked me up a cap and rotor hoping this would solve my problem.  I went home and put on the new cap and rotor, still won't start.  I've been told it could be the ignition control module but i'm not exactally sure where thats at and how it can be replaced.  If anybody has any suggestions or any information that could help me, it would be greatly appreciated.

Thanks-

Go to www.autozone.com and look at their repair guide. All you have to do is enter you trucks info and its free.

It does not appear that blazers are in their database..
 
 

Jimmy's are in their database but that seemed to be no help....

Does your motor have the coil that connects to the top of the distributor that might have gone bad but I don't know how to test that!! I would pm swartlkk and ask him maybe he knows how to possibly test them!!

The best, and easiest way to test a coil and an ignition control module is to remove them and bring them to an Advanced or Autozone.  They have the proper equipment to load these electrical devices up to operating voltage/current levels where they can be tested for proper operation.  This is not something that can readily be done in your driveway.  Semi-functional testing can be done, but many of the failures that occur with these parts are related to electrical load and heat, two things which cannot be easily duplicated without some specialized equipment.

Hope this helps.

My local autozone doesn't do that.  I think i'm just going to end up spending 150 on a coil and module and hope that works.
 
Thanks-

Do you have an advanced auto?  They should do it.  The reason why you test these things is so you don't have to take the shotgun approach to auto repair...  LOL
