99 passport electrical problems

I am working on a 99 passport with the 3.2L. It is missing on all passenger side cylinders. I have checked every sensor on the engine and all are good. Checked injectors and coils. I just don't know where to look next. It will start but revs up very slowly. I pulled the coils on the passenger side and all are sparking fine. I can pull the coil wires and injector wires on the same side and the engine runs the same. But on the driver side it will kill the engine. Now I just don't know what can cause this to happen. I was thinking bad crank sensor and cam sensor but both are good.Could this be the computer or possible a broken wire. Any advice on what wires to look at first or if a computer would cause this maybe.
All advice welcome.
Thanks,

Did you recently do any head work? Almost sounds like your cam timing is off on that bank of cylinders. Also, check your fuel supply to those cylinders as well.

Check the wire connections under the power steering reservoir for corrosion or if one came loose. There is a seperate connector for each bank.

It has recently had head work done. But the problem is on the opposite side. I have no less than 190 psi on all cylinders. I have had those connections apart several times and can't figure it out. The plugs are wet on that side so I assume it is getting fuel. I pulled all three coil packs and they are getting spark. I checked the fuel pressure and it is at 40 psi. if I remember right. The only code it will give me is a multiple cylinder misfire. I am kinda leaning toward the computer but hate to spend the money and it not be it. Is it possible for the computer to only run one bank? I just don't understand the fact that the problem side seems to be getting both fuel and spark but wont hit a lick. Is it possible there is a problem with the reluctor ring on the crank and the crank sensor is reading it wrong? It just has me so puzzled I am at a loss for what to do.

If its getting fuel and spark the only thing missing is air. I'm thinking the cams on that side arent timed right.

I will check again and let you know. I thought the same as you but checked them once before. Who knows, stranger things have happened.

Can't befieve it myself. Timing was off on passenger side. I don't know how I messed it up but I did. I guess it just took two or three people telling me it was off before I checked again. Thanks guys.
