Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
You do not have an oil pressure problem. You have a problem with the oil pressure sensor wiring circuit (harness compromised or dirty azzed connector that needs cleaning with CRC Electronic Cleaner, or both). Spray the living chit out of the oil pressure sensor connector and the sensor connections side as well. Let those dry, then connect it back together. If your light still comes on, trace the wiring.

did that sprayed half can actually done it multiple times still I drive 5 miles down road ding ding ding oil light
Doubtful signal loss only at operating temp? Easy to check wiring with jumper wiring. @ the PCM connector pin #15 tan with black tracer & pin #36 purple. Back probe connectors with jumper wiring and run to operating temp to verify.
Update car lot wanted 2nd opinion psi 4-5 barley today they trying just replace oil pump ? Do you have removed the motor would it be better just replace whole motor ? Looking for options on what tell them

I’m assuming your saying replace oil pump correct me if I’m wrong but oil pumps don’t fix low oil pressure correct? The low pressure is due to wore out bearings? Meaning the motor just wore out at almost 200k miles ?

I'm not saying anything!
I just posted a diagram showing no need to remove the engine to replace the OP.
Btw, the oil pump is a simple design, like a water/steering/sump/pool/aquarium/pond,etc..PUMP...fluid is drawn up through the pickup screen, and dispersed. The pump needs fluid & a clear screen to operate properly. Look back when you used seafoam. Flush again or drop the pan and clean the pickup screen. Oil pump pressure is checked at the outlet of the oil pump after the filter. Here's a map for you: PICKUP TUBE>Oil PUMP>FILTER>OPS.
Ok update they said they hear no abnormal noise from motor that they replacing oil pump and pick up tubes while I don’t agree on this since pressure was below 5 psi what’s y’all opinion will this fix it? They said it would honestly I’ve had this hummer barrel few months and my headache is bad lol
