    1985 S 10 Blazer will not start. I have replaced pickup coil, dis cap, module, ignition coil, and I am not getting any spark to the plugs.

    Perhaps an ECM issue?

    These trucks are carbed, right? Pretty sure they still have a computer.

    Check all your wiring over.

    Could still be other issues in the distributor too. I assume you replaced the rotor at the same time as the cap?


    I am not really familliar with the setup on these.

    Is the distributor even turning, ie: timing chain. Just a thought. If it is a carb, the ignition system is not computer controlled. I f the pickup coil and module are good and the distributor is turning and assuming you have power to the right places, you should at least have spark out of the ignition coil. :D

    Check for fire at the plug. Check for fuel. all ways start with the basics.

    I think he answered that one in his second sentence. The basics. Compression, Fuel, & Spark (@the correct time). All needed in order to run.

    Check your ECM-B fuse, if it's blown look under the carpet in the driver's side footwell. The wiring tends to wear through under where your feet usually rest and short to ground. Without power in this circuit you will have no spark and the fuel ump will not run.

    But if someone searches the archives, there's some good info here that could possibly help others :)
