Car has code P0016, both intake and exhaust camshaft sensors have been replaced. Car feels like it wants to start but it doesn't. I've also replaced timing belt with new tensioner and idler. Compression per cylinder is 135 psi. There's spark from coil pack when cranking and fuel pressure is about 60 psi. I would like to check signal from camshaft sensors at ECM but don't have access to wiring diagrams. Any help you can provide me with I'll appreciate it. Thank you.

Hi,

I attached the entire power-train management wiring schematics. I had to break each pic in two to make them readable. I did overlap the to make it easy to follow. They are in order.

Let me know if this helps.
