Recently ive had a no start problem with my 1993 chevy s10 blazer. I recently (last week) had a similar problem so I replaced the spark plugs, spark plug wires, dist. Cap, rotor, and also the coil and ignition module. The problem was fine for a week I drove it approximately 500 miles without missing a beat. This morning it was like -2 out so I decided to fire it up before work and then it shut off and would not restart, it would crank fine, no ck engine light or any other noticable problems. So I tried starting it once again and it turned over about 4 times and fired right up. So I figured problem was solved. Being too cold? I was then in my house and it was running for a few minutes and once again it shut down. It cranks but will not fire up. I added a few different types of treatment to the gas also. I believe the problem may be spark related, but I have no idea where to begin my troubleshooting>?

Well you can remove the coil wire to see if you are actually losing spark. If you are losing spark I would suspect the pick up coil, this is the last piece of your ignition system that has not been replaced yet and will give you the symptoms you have. It might be wise to buy a remanufactured distributor rather than trying to just replace the pick up coil due to the fact that your main shaft in the distributor is also probably bad too. Hope this helps. Ps I have worked for gm for 10 yrs and have had this complaint a million times.

I checked. No spark at the coil. How hard is it to replace the pickup coil rather than the entire distributor. The only reason im asking is because the motor in it was a brand new crate motor approximately 45-50k miles ago. Thanks again.

You will have to remove the distributor and press out the pin that hold the gear on the main shaft, then pull out the mainshaft to access the pick up coil. Its not hard to do just take your time and be sure it goes back together the same way it came apart. (There are a couple washers on top of gear, thats all)

You dont actually need a press, just put gear in a vise and drive out the pin with a hammer and punch, it will come right out.

PROBLEM fixed, I removed the distributor and looked at the pickup coil, it looked to be in terrible shape, so I replaced the complete distributor witha reman unit, reset the timing, no problems!
