That's an oil pressure _gauge_, and more exactly, it's not really a gauge. The sender is just a switch that closes when oil pressure reaches a certain minimum (something like 8 psi). Then the gauge just moves to the middle position.
The sender is located in the HPO reservoir, so what you're reporting indicates that the reservoir is likely draining while the truck is parked. So do this - right after shutting down, remove the top plug from the HPO reservoir and check the level. Should be at/near the top. Then let the truck sit for several hours and check again. If the level has gone down, you have a drainback issue.

Okay. Checked the HPOP reservoir after I let it set for the night. There's oil still right at the top of the reservoir so I don't think it's draining. Maybe it's something I just have to live with, cranking for 10 seconds before it will start? Is that common with efuel systems? I did look at fuel pressure - 65-70PSI so I think I'm good there.

10 seconds of cranking...I'd try to fix the issue before living with it. I'd at least put a new connector on the IPR and truly confirm you do not have a drainback issue, your dummy needle for oil pressure should hit midway after only a few seconds, however that will not be the reason behind the extended crank times.
For 10 dollars put a new pigtail on the IPR, if wiggling it makes it work or not, obviously the connector is probably shot.

Sorry for not getting back to everyone. I'm a die hard Steelers fan and just made it home in time for the game. Hopefully I will have time tonight to install the new pigtail and retest.

Okay, replaced the pigtail, brand new connection. Same issue, have to let it crank for a bit before it "kicks on". The dummy needle for the oil pressure kicks over right when the engine starts. Not sure if that means anything.
The fuel pump starts up right when I turn the key to get the glow plugs warmed before starting. I'm getting a solid 70 PSI so I think the fuel system is working fine.
Sorry for the dumb question, but would the PCM have something to do with the delay?

I doubt it. Did you have this problem before installing E-Fuel? Did you do anything else while installing E-Fuel.

Just put a wicked wheel 2 and rebuilt my turbo. Didn't have this problem before the efuel.
I guess I look up the ICP as a cause? I'll start searching threads.... doesn't make sense so far.

Okay, please hold. I picked my daughter up from school (residential driving) and let it run for about 20 minutes. On the way home I jumped on it a little (responded great) and shut it off. Waited about 10 minutes and it started quicker this time. Maybe I just need to drive it around town a bit more.
Going to let it sit for the night and try again tomorrow.
