Crank No Start after 3 months of repairs and troubleshooting please someone help!

I have. And it still won’t start. They are basically doing the same thing I’m doing so I’m saving on the labor. Im pretty mechanically inclined but have never ran into a issue as this one. So I’m doing my own Process of elimination. All the parts are original. They needed to be replaced anyhow. If you have anyone in mind that could give me some sort of advice besides the things I already know it would be appreciated.

I am doing repairs as well on my 2003 Mitsubishi Eclipse GS 2.4L after it overheated on the freeway in NM and I blew the head gasket. I'm not a professional mechanic but I decided to give it a whirl since I know just about enough to be dangerous. The head cylinder was warped beyond repair and I had to buy a new one. Removal was simple, and like you, I also decided to replace many of the parts since the car has over 140,000 miles on it. Including new water pump. Thermostat. Spark plug wires (the old ones fell apart when I tried to remove them), upper and lower radiator hoses, camshaft position sensor. Timing belts, and temperature sensor. I am in the process of placing the timing belts on and should have it done by this weekend hopefully. Interesting that you done all that work and it still would not start. Are you getting spark? How about fuel? I sure hope after all the work I am doing that the car starts. My guess is that it is probably something very simple that you overlooked. Have you checked all the fuses and relays?

Probably the Ignition switch
