Hard time starting
 
I have 01 and has been acting wierd in mornings starting up. It's done this now four times in the last year it happened twice this week though. Go to start it up in morning fires up then shuts down right after. Then cranks over but wont start. Got it to fire up the other day after jump starting it but didn't seem to want to fire up forever when jump starting it off father in laws truck. Checked fuel filter connections since changed it just recently think it could be something fuel related? Checked didn't see any fuel leaks when primed it.

Did prime the fuel and started up shortly after. So going to change the rings out on filter and see if thats maybe causing air to slip in.

I had similar problems. I got a rebuild kit for the filter housing and a new wif sensor and the aluminum bleed screw and it has been working good ever since.

Now my check engine lights on saying i have high rail pressure
ether fuel pressure sensor (connection/wire loose or broken will make it read max psi) or CP3 regulator valve (FPRV) sticking, burned, or otherwise not working right

what codes have you got?

Was the bleeder screw. Screw was stripped good. Ordered metal one online installed it and has ran good now.Seen on here few times what people write in for the problem but not give the final piece of the puzzle. Figured I'd show the answer to my problem. Thanks for the suggestions.
