Yes and the only codes I get are bank 1 sensor 2 not responding also bank 2 sensor 2 same thing
​​​​​​I've recently performed a compression test on all 8 cylinders and the best reading was 60psi the lowest bring like 10 average is 30 - 35
Now I did have the intake manifold off cleaned it up cleaned the gasket surfaces well, and using RTV, the red label stuff for high temp, I reused the old gaskets only because I was curious if it might finally start with the injectors and manifold cleaned out.
No start though.
That's when I did the compression test.
When I removed the plugs they had no oil or anything on them, strong smell of fuel is all.
I know the compression specs for the 4.4l is 125 psi - 150 psi right?

 

I am pretty sure if O2 sensors are not hooked up the vehicle will not start. So if no O2 response, you need to look more into that. Fuse, connectors, etc.
That is wicked low compression, that can easily also cause a no-start - you may want to double check your numbers and make sure you were reading PSI and not bar - which would still not make sense cause 60 is like 800psi.... but.... And yes, 130psi or higher is best for cylinder compression.

 

Yes and I rechecked all 8 cylinders again for compression and got the same readings it went like this so driver side cylinders 135 and 7 1 was about 35 PSI three and five barely registered at like 10 or 15 and 7 was about a 35 passenger side those cylinders were better but still way low 60 70 and then 65 I believe I'm not showing any oil getting on the spark plugs are in there from what I can tell I mean I took the spark plugs out just smell like strong smell of gas although I did take the fuel pump fuse out so I could crank it you know anyway I'm trying to decide if I want to spend the time and tear the heads down check you know head gasket Etc and fix all that stuff or maybe just try to sell the thing as is not sure what it would be worth you got any ideas? And thank you for your quick response to my previous inquiries

 

Dump some oil in each cylinder, not much tho, and try compression again. Maybe you washed the cylinders with fuel.
