ok hear we go again my 93 s-10 blazer would not start the other day would crank found out it had no spark so i rapped the coil with a wrench and it took off don't know why it is still running i did this 3 days ago if the coil was bad shouldn't it of quit and stopp running by now?????I put an a/c delco replacement on it last year from advance auto.
olthing has 150,000+ on it and is still runningalso cannot seem to get the drivers side rear door open what can i do about that??[X(]thanks for any help you can give John..

 

Buy a new coil, just in case. When the current pukes and dies, just replace it.

As for the door, this is not going to be easy, you will have to remover the inner panel to access the locking mechanism, prolbem is the door needs to be open to take the inner panel off. Worst cse you destroy the inner panel and replace it with a new one. however, if you only use as much force as needed, you might get lucky and get it off without breaking it.

Once you get the door open, more then likely the grease on the door lock is stuck. you will need to clean it up and regrease it. You might be able to use PB Blaster in the key hole, like most of a can and it will run all over the place. If that works you need to clean the PB Blaster up, and use powered graphite to lubricate the lock. Another lubricant in key lock will cuae it to atract dirt, which will eventually gunk up the lock.
