Silgs300

Problem started with a leaky valve cover, there was oil in the spark plug holes. I was getting misfiring codes. After putting everything back together, I smashed the wiring that plugs in to the coils. A previous owner had replaced all the coil wires and just had them sitting in the between the valve cover. Car started and instantly shutdown, realized my problem.

Cut out that part of the harness from a same year sc300. It was reconnected to the harness with butt connecters. Spliced it with the wires the owner had used. I wanted to properly reconnect the harness pieces to the right conections, also wanted extra wiring incase a mistake was made. There is power going thru the ends of the coil pack connectors.

Put everything back together, tried to start it. The ignition fuse wasnt getting power. Checked all the fuses and replaced the am2 fuse in the bay. It cranks now, sounds horrible but wont start. Ive check my battery and fuses and relays i check the starter everything got power.....im stumped

Solved....Head gasket lol. It is alway the head gasket with me. When testing for spark I was using an extra spark plug. When the actually plugs were pulled and cranked, coolant and gas blew out. Looks like I've got a could fun days ahead of me.
