low oil pressure on start up

[Twilight Slide]

So I have a 1g GSX. Unlike most cars I have owned, the OP doesn't shoot up on a cold start. It will stay at about 0 until it warms up, and then stays around 10 at idle. If I baby the car and don't mash on the gas, it won't ever raise above oh say 25. I have to do maybe 2 or 3 full gear pulls before the oil pressure will go up to the 50-75 range. BTW I have a Autometer Oil pressure gauge. Previous owner installed it. He said it's tapped into the stock sender's spot. Somewhere by the oil filter it looks like? Anyways is there a way to check the sender? Owner said there's some kind of isolator too, so that hot oil isn't in the cabin. . . can the isolator go bad?
TIA

have you checked your oil pressure??? my car is going though alot of oil right now because my turbo is needing a rebuild so I am constantly checking it and when she is getting low the pressure runs alot lower. Check that out

I think he means check your oil, period. Indicating he experiences low oil pressure when he is low on oil.

I know from reading 1000 FAQs that oil presure in our cars is not uncommon to idle around 12 psi

its probably your gauge or how its hooked up.

These cars naturaly have low oil pressure off idle sounds pretty normal except the 0 on warm up

Oil level is good, car burns a fair amount of oil, but no leaks at all. The pressure at idle doesn't bug me, its the fact that it doesn't shoot up and takes so long to reach good pressure. How could the sensor/gauge etc. be hooked up wrong?

all i know my boy did something to the unit that reads it now mine is fine ill ask him. check the compression also. do you have alot of miles on the engine?
