OK this is a hard one to describe. First off let me say this I've replaced everything now, distributor, pick up coil, icu, even the ecu and I'm still not getting any spark to the plugs. My truck was running fine but when I had the air cleaner on it it would cut out and die sometimes. Found out it was the air cleaner Housing sitting on the coil wires well one day I had it running and I just touched those wires and it died ok well since then I haven't been able to get it started again. I replaced everything as I previously stated. But when I go to check what codes are there now it's a 95 Yukon obd1 so I ground out the cel light to flash my codes well instead of flashing 12 it's flashing 13 weird but the kicker is when It flashes 1 then goes to the 3 it clicks on the third one like the egr valve solenoid and fuel pump relay both click and it does it over and over and over now did I fry something or what will get a video up asap

Post the wiring diagram(s) you are using for the Fuel Relay and EGR systems, then any responses from us match your system. Diagnostics, not parts cannon.
Also please attach links to your previous posts as all this may be connected.

is it spark issue or fuel issue? Did you replace your plug wires? I’ve had one of my plug wires arch to the block before from bad insulation. You can volt test your distributor output and also volt test your fuel pump and relays to make sure you didn’t ground/short any fuses or anything.
