So like the title suggests, I can't get my 94 S-10 to start. I was gone for three months and when I came back it wouldn't start. My roommate was suppose to be running it regularly while I was gone, but it's hard to say whether he actually did. But anyway, to get to the point....

I'm going to start off by saying I'm not too good with cars, so I had a buddy helping me out, but this is what we've checked so far:


My battery had died, so I replaced it.
Once I got the battery replaced, the starter is cranking and the engine is turning over.
I could smell gas when I took the air intake off to spray in some starter fluid, so I'm pretty sure the fuel pump is working.

I found out that there is no spark. I took off the ignition coil and there is no voltage across the input terminals for it. From this point, I'm not really sure where to check. I'm thinking maybe its a grounding issue or maybe a short somewhere, but I'm not quite sure where to check at this point.

Any ideas of where to go from here? Also, anybody got a circuit diagram for the ignition system?

Try checking the IGN fuse in your fuseblock, and then see if you can run a lead from your battery to the positive input on the coil and see if it runs that way..

 

I would suspect the ignition control module in the distributor. Pull off the cap and 2 screws are what hold it in. Then it unpligs and you can take it to an auto parts store and they will test it for you for free. This is what controls the input power to the coil and you have none unless I'm not reading your posr correctly. You can't test the module yourself. It takes a special voodoo machine. You can test the pickup coil however. If it isn't the module post back.

 

Check the computor codes, Same thing happened to mine it was the crankshaft sensor behind the crank dampener. Just happened all of sudden, no warning at all.

 

Sorry for the late reply. Thanks for all the input guys.

Since I've been busy since I got back in the country, I didn't have time to check everything. I ended up taking it to the shop where they diagnosed it as the ignition control module. I guess it had burned out at some point. I guess my distributor cap and rotor are also on the way out. But it's running now... hopefully long enough till I get a new car.
