RE: start trouble
If it's an automatic, have you tried staring it in all gears?
If you have 2 people, check for power at the "s" terminal at the starter motor with someone holding the key in the "crank" position.
If you get power to the "s" terminal, try tapping the starter with a hammer. If it's an old starter you might have worn or sticking brushes.
Sounds like a possible ignition switch
Check for good battery connections (corrosion)
Can't think of anything else at this moment

RE: start trouble
I have a 97 blazer also. My blazer will just die sometimes when I'm driving or sitting at a light. If my blazer is parked overnight and I come out to start it starts rights up on the first turn of the key. If I go to the store and come back to the blazer I will turn it halfway and no dash lights come on but if I wait a minute the dash lights come on and I turn the key the rest of the way and it starts right up. The shop can't figure out what causes this problem. They changed the battery still dying. The change the distributor cap and ignition control module and it's still dying.

Hey Dino55,
Why wouldn't the shop know that or tell me that? How do you that is the problem? I heard the 97's are bad for their ignition switches.

RE: start trouble
ej- ignition key. Because you don't have power at the starter when hot. Could also be a partially fried fuseable link. The fuseable link is within 12" of the starter. If it shows any sign of swelling or discoloration, replace it with another fuseable link. You could also have a bad connection on the starter. Clean the contacts, posts, where the wires attach to the starter. Don't just look at them, take them off and clean them. It doesn't take much corrosion at all to create problems.
super- ICM, ignition control module. Becuase yours dies when hot, and starts right up when cold. Most auto parts stores can test it for free. Make sure you use the grease when you put the new one one. The ICM doesn't react to heat well, that grease helps dissapate the heat so you don't fry your ICM.

Hey Hanr3, they already replaced the ignition control module and it still dies sometimes. Thanks Dino55 I will have the shop take a look at the ignition switch.

Did they put the grease on the back side of it?
