:dunno: what year are your cars?

Even if the gauge would be on, it should still show oil pressure stock then as the oil would be cold and quite thick

^my pump is 8k miles old, does not show oil pressure on either stock or aftermarket during start, once its started both gauges turn on. Aftermarket shows about 60 PSI IIRC. Its been awhile since i've started the car b/c of the fire

I guess its not a wiring difference then. Ill have to check out the TSRM tomorrow. Have you guys upgraded wiring at all, ie bigger gauge, extra grounds etc? I would think there is a switch when the key is turned over, but then maybe the starter just draws that much power on a mostly stock wiring setup to disable most electronics.

I should have my car about ready to start for the first time tomorrow. While i'm priming ill pay extra close attention to the gauges, maybe i just never looked close enough?

I cranked mine over two or three times in 30 second intervals, til I saw 2-3psi on the stock gauge while cranking.

I'd be happy with 50%...

The oil pressure gage is on IG1, which remains hot during cranking. The radio goes off because it's on the accessory line, which doesn't. Whether pressure shows on the gage depends on several factors but it's not because the gage isn't powered.

...what you need to do when priming a new motor is pull the valve covers, plugs, and injector resistor and crank until oil flows out of the cams with no bubbling, if you get pressure on the stock gauge, good. Then fire it up and look for your pressure again...

Oil pressure is hit or miss, and all the pressure in the world doesn't matter ONE bit if you aren't getting oil flow everywhere, and checking at the highest point (cams) is the safest bet for priming, then worry about pressure.

There is a whole lot of misinformation flying around in this joint... ...back home (celicasupra.com) we have people labled "BS POLICE", and you get slapped on hard for spouting about stuff you don't know. It's not the most friendly thing in the world, but it might help considering if one were to follow every suggestion in this post, they'd have wasted hours of their time and done it rather incorrectly.

And that's fine until they start posting it as fact then get all butthurt when corrected....

A LOT of the bad info has the potential to cost people $$$ if followed blindly.

There are a few "members" here I'd make "read only" If I had my way but I'd be accused of being a Nazi.
