Did you do your research on what sizes are in the kit? Did you research the thread size of the OPS?

LOOK BELOW:

 

Of course not. Stupid me lol. I ordered the right one

 

This kit is quick disconnect like air tools. MAKE SURE GAUGE HOSE FITTING IS SECURELY CONNECTED(TUG ON IT) BEFORE START UP, and check for leaks after startup. Let it run and watch gauge until engine reaches operating temperature, post the results.

 

will do thank you so much

 

So I got the new kit, plugged it in and started the hummer cold start was at 65psi and fully warming up the engine at idle it start to go down and it stopped at around 14psi

and since I changed the oil and put new one and new sensor and wire harness it didn’t happen again since then. I had few cool days that I thought maybe it’s cool but what I ment cool was in the 70s and today is 80 and still didn’t do it .. so I assume problem fixed? Lol

 

14 is great I also replaced my pigtail that plugs into the oil pressure switch new oil after they did all that work I’m at beach over 200 miles knock on wood no oil light can you post when kit you ended up getting

 

sensor range for actuation is 0.4-0.5 bar. Check your sensor when it works. This can be done using a pressure gauge and an air compressor.

 

Took a while to get there, but good job!

 

the test kit is the one above in the replies , I replaced the sensor and the wire that plugs to it and then did oil change and put fresh mobile one oil and filter

 

yes but I am glad it didn’t come back so far so I pray it’s fixed lol but thank you and everyone else for their help to solve this issue
