GP1138 Posted November 11, 2007 Report Posted November 11, 2007 So the engine in my car has been replaced... is there a possibility that they could have gotten the engine from a car with no oil PSI gauge? My pressure gauge always sits in one place. I was revving it the other day and noticed it didn't move at all. Temp gauge works fine, doesn't read one single reading. How hard is the sender/sensor to replace? You can see in this video, it doesn't appear to move. The engine was plenty warm, too. Quote
ManicMechanic Posted November 11, 2007 Report Posted November 11, 2007 Very possible...You need gas and a new sender should make the op gauge work. Quote
Chancho Posted November 12, 2007 Report Posted November 12, 2007 Yea you might need to get a new sending unit, and a little gas would help you get anywhere far...lol Quote
gp90se Posted November 12, 2007 Report Posted November 12, 2007 Put the other engine back in so the gauge works Either the resistor in the harness needs to be removed or the OPS is wrong. Quote
mfewtrail Posted November 12, 2007 Report Posted November 12, 2007 John, you have the standard gauge that uses an oil pressure switch. It's normal for it to sit in that area and stay there all the time. Quote

GutlessSupreme Posted November 12, 2007 Report Posted November 12, 2007 I don't know about GPs, but the Cutlass didn't go to switch-only until '93. '92 cluster should read. I know my TGP clusters have/had working ones. I'm placing money on a switch being in the new motor rather than a sender. Quote

Only the 1992 3.4 Cutlass and some 1992 3.1 Cutlasses (Internationals perhaps) received the sending unit with numbered gauge. All other 1992s had either the base cluster or H-L "gauge." Until I am proven wrong. lol Okay...After a little research, it seems early 1992 CSs (below VIN 320,000?) and all 1992 3.4s had a numbered working gauge. Quote

Thanks though. john, and ev eryone else.... my 92 vert HAD a dummy guage. It works now, because the swapped in motor came from a car that had a working oil gauge, along with that car's wiring harness. try grabbing and swapping it the long type oil sender, that may fix the problem.... although I have never found a resistor. if the resistor exists, you may not read full scale but at least is will still fluctuate. lemme check something. I'll get back on it. Quote
mfewtrail Posted November 12, 2007 Report Posted November 12, 2007 You're saying I have a dummy gauge?? Just seems silly to me. Thanks though. Yep. I have the same dummy gauge in my '93 SE. If I think about it, I'll compare the wiring between the two different types of gauges sometime soon... Quote

The 1992 FSM doesn't show a resistor... Quote

My '92 SL has the 'Gages' (full analog gauges) cluster, with all working gauges, not dummies. I have no idea what the VIN is off hand. Quote
19GT92 Posted November 13, 2007 Report Posted November 13, 2007 man you have the same car as me... go to your local parts store and ask for an ops switch for a 1992 gp se with the gauage not the dummy light because in 92 the 2 doors and the 4 doors had different dash setups. you do that then its all good and the sender is right beside the oil filter on these engines. if you need anymore help pm me Quote
