I think I have checked relays and fuses like 6x already. The vehicle was working 100% before any work started.
The work done was to do some simple maintenance to the 2nd air pump crap that's under the intake. At that time I had to clean out the intake because it had oil from PCV laying in bottom of intake, I then replaced the fuel injectors, and installed new plugs.

The 'new' injectors came from a 2007 107kmi 2UZ-FE Tundra wreck (ebay), they are OEM injectors, I then sent them to RC F.I. in CA to be serviced. The report shows they were fairly bad, but after service the report shows them good & matched.

I will now go probe some injectors, check ohms, hear them click open, probe the wires to make sure they are getting turned on.

I made some break-out patch wires so I could probe cam sensor w/o stabbing the wires.


cam sensor appears to be ok.
