I let the gp light go off each time ...

95% of the time it takes 3-5 seconds to crank...other 5% it doesn't even seem to turn a whole revolution.

My icp @ cranking is usually 800-1100psi

Glow plugs??

Check the FICM, and then your batteries if the FICM is toast

Load test batteries, then check ficm if the batteries are ok.

Hmm, it could be the GP's. Have you tried cycling the key twice? Let the GP light turn off before cycling. Maybe they're weak :dunno:

How's it run after you get it started?

Runs great

Glow plugs are cheap...how hard are they to replace

You need a monitor to pull codes, I personally don't think it could be glow plugs unless it's cool outside. Glow plugs are not hard, just can be tedious. Jmho. Do you use motorcraft filters and caps? I also have about a three second start from time to time, it doesn't bother me, I do know my batteries are taking a crap, I see around 10v when cranking on the monitor, I know that is bad news. I'll be changing them soon.

No codes. Seems like plugs. I can cycle the key twice and cranks first turn

I would investigate fuel pressure then, turning the key twice does not make the glowplugs work better. If the glowplugs were bad, you would most likely get codes. I'm not trying to be difficult, but your wasting your time worrying about glowplugs, unless you are in a cool environment. You would also see white smoke prior to startup with failed glowplugs.

There isn't a way to read fuel pressure on the insight without the accessory is there?

No you have to buy the fuel port adapter fitting and hook up a analog guage. Do you have the blue spring update?

It is best to check fuel pressure, then if bad, install blue spring update. Then recheck pressure.

Can a port be tapped into the oem plastic cap? Is it thick enough?
