Re: Slow morning starts (no fuel pressure?)
Mine is doing same and I highly suspect glowplug(s),GPR, or associated wiring.
Someone here should be able to give you "DIY checks" directions, as I am at library for internet.
The dealer I bought truck from told me they replaced 6 gp's, but wanted mechanic to replace all eight, but parts store only had 6 in stock, so...
Think he was "telling" me that the truck needs two more gp's replaced.
