    Default No Spark - Need help/advice

    My name is Rich and I have a 1989 Suburban V1500 5.7 . It was running fine and I shut it off about 2 weeks ago. The next day..NO Start. Engine cranks but NO spark. I have replaced the coil and had the Engine Control model checked by Autozone and Advance Auto. It tests good. I replaced the Dist. Cap and rotor and have checked voltages to the coil. All checks okay. Still NO Spark. I am leaning to either the Pickup coil in the Distributor or the ECU. Any suggestions on how to test these? Any suggestions would be appreciated....Rich

    Welcome to the Club!!!

    I moved your thread to the correct section of our Forum and changed the title slightly to more match your topic. This should help in getting you more responses/opinions.

    Unfortunately, I do not know what the issue could be, thus cannot be of any help to you in that area.
