CUCV Starting issue

[nvrescue]

My latest M1009 1985 CUCV as shown seems to have a hard start. The previous owner claimed to have replaced the glow plugs, made good connections to glow plugs and he also replaced solenoid and bypassed original system with a manual push switch (I also did this on other CUCV). I press the glow plug relay and here the solenoid and hold for 30 seconds and crank and crank and crank then a brief fire and then I do it over again. On this particular one, after second pushing of glow plug button if I press gas pedal a couple of times and hold it down it will start then go through its higher idle then after 3-5 minutes drop down to normal idle.

Am I missing anything here, my other CUCV's start easier even with manual glow plug override.

I would love some suggestions or comments.

It's sucking air or clogged filters.

I will change Air, however it looked new, maybe fuel? Do you happen to know if there is a parts cross reference list or know what part number for Fuel Filter from NAPA or KRAGEN or AC DELCO? We spoke last night huh.....how is it going?

FUEL INJECTION:
Fuel filter is NAPA# FIL3136; FRAM#P3940A

Go into the TM's and trouble shoot according to the manual. Are you sure the glowplugs were replaced and are new? Were they tested IAW the manual? Is the push button correctly installed?

Laurence,

Go to this link and copy and paste my two posts, they are most of the FAQs organized for easy reading.

Copy them into Word or whatever program you have, print them out, they are 27 pages, and then keep them in your cucv as a quick cheat sheet.

Sorry I ment fuel filters.

I will re check voltage to glow plugs too. I do hear the solenoid engage with a solid click and hear it release when I let go of button. Also see voltage fluctuate. Only thing with glow plugs now is to verify voltage. I will change for piece of mind Fuel Filter and Air Filter, check water seperator if it has one (I forgot) and give this baby a full fluid change of all components including diffs. If still hard start, I will pull some glow plugs for eval.
