Hi, I recently came across a 1986 c10 with a 305 it looks in pretty good shape and interior is really good. He says it has no spark, he put in good used distributor, new cap and rotor, new coil, new fuel pump too. still no spark. i was wondering if it would cost much to get it going? Maybe you guys would help me out? he said it just quit and would not start the next day. It for sure has no spark he just checked.

Hello,

It sounds like the ECM could be bad. can you remove the distributor cap and crank the engine over to see if the rotor spins? Lets run the codes. here is a guide to help us:

Can you please shoot a quick video with your phone so we can see what's going on? that would be great. You can upload it here with your response. Please run down this guide and report back.
