93 3VZE Cylinder 6 intermittent misfire

I have a 93 4runner 3vze with about 260,000 miles that has no spark on cylinder 6 most of the time. It will only start if i am pushing the gas pedal and runs rough most of the time. It will periodically start sparking again after running for a while. and then again no spark when i pull the wire from the distributor. I have periodically smelled gas in the truck while driving.

I did the timing belt and water pump a few months ago and it ran fine after that until about a month ago.

I just replaced the pcv valve and valve cover gaskets after i saw a small waterfall of oil dump from the passenger side gasket after just starting the truck. Also because i found a significant amount of oil in the throttle body and air intake pipe

Ive replaced the plugs, wires, distributor cap and rotor with no change.

I replaced the fuel pump and filter about 9 moths ago.

not sure what i should check next and in what order. Any help would be greatly appreciated. also not sure what other information to provide.

Welcome to the forums!

How good are yer grounds? Have you inspected the ignitor? Another thing to check would be the crankshaft or camshaft sensors and wiring harness associated with those sensors.

Thank you for the welcome. I have not checked the grounds and the wiring looks like something out of a horror movie above the inlet and to the injectors. I was literally shocked when I touched the ignitor so I will have to look into that. I am going to order a distributor and install it anyway so that should cover the crankshaft sensor. Thank you for pointing me in a direction. I am working on learning the electrical aspects of working in this truck. I will let you know what happens.
