Got it. Thanks for information. Just took a look at it. I will check it this weekend. I think this the issue my friend was trying to tell me about. If I remember correctly, he said he put in an extra quart or two of oil and his cranked better. Does that sound logical? If the oil level is higher wouldn't that mean the leak back couldn't go too far because of more oil? Or am I totally losing it?

The cap/plug of the HPOP reservoir is on the top of the HPOP reservoir. I think it has a hex allen fitting in it.
The T6 is diagnostic as well as helpful, if you have this problem. If it can extend your injector use time, it's easier to get your options and plan for the expense and project.
It would stink to replace injectors and still have the same problem
At least that's the intention

If you open it up after sitting for a while and the level is low then need to figure out where it's leaking down. If it's close to the top then back to trying to figure out your original problem.

If it's leaking down overnight then adding more oil won't help, it will only increase your overall oil level. The low pressure oil pump sends oil to the HPOP reservoir. There is a standpipe in the res that sends excess oil back to the engine but keeps enough in the res for the HPO system to operate. Oil level should always be about 3/4 from the bottom of the opening where the plug is.

Got it. I will check it as soon as possible and post back. Thanks again. Great info from all.

As to the long first crank, I'd guess dirty battery cables or starter.

OK I am just getting back to this problem. Before checking the high pressure oil pump, I thought I would test my batteries so I borrowed a real fancy load tester with print out. Take a look at these measured numbers and see if you guys think I got a battery problem also: I tested both batteries after it sit all night.
Battery 1
Voltmeter: 12.39 (before test)
Test (CCA):
Volts: 12.36
CCA: 579 (rating of battery 750 CCA)
Test (CA):
Volts: 12.33
CA: 726 (rating 885)
Battery 2
Voltmeter: 10.81 (before test)
Test (CCA):
Volts: 10.78
CCA: 54
Test (CA):
Volts: 10.72
CA: 72
Question would be would that 2nd battery (low) cause my long first initial start?
Thanks guys

Buy two new batteries or the old good one will pull down the new one.

Problem Solved
Don't like to leave hanging threads:
Two new batteries fixed the problem. HPOP was good. Thanks guys for the suggestions and answering questions.
Suggestion to anyone reading in future: Save yourself some trouble......borrow, get or buy a battery load tester. I'm putting one on my xmas list.
Thanks again. This site rocks. Jed

Glad you solved your problem, thanks for following up 
I've had good luck with this load tester: https://www.amazon.com/gp/product/B000F5HU6W
I've also seen first hand the shortcomings of the parts store's digital "estimator." They call it a battery tester, but with the tiny little wires, it CANNOT do a full load test.
It failed to detect a battery that wouldn't hold up under load when I was chasing a bad starter that had more draw than it should have.
Load tester found it as bad, their thing...wrong. Just a caution there for those who go to parts stores to get their batteries tested
