99 stroker that will not start(and love this old truck)

[Zero Gravity Tower]

I have a 99 stroker with a auto. The truck always has started hard and in cool weather we had to plug it in, now it will not fire at all!
Truck will turn over but not kick over!
It has new glow plugs harnesses and relay(these where installed a year ago,and did not help starting at all!), this moring i checked relay and glow plugs and they seem to be good!
I am not a diesel mechanic but i can turn a wrench, i just need a shove in the right direction!

I am tired of taking it in to get fixed(with no changes) so i am going to fix it myself, hard to keep throughing money at this good old truck!

If anyone can help, please let me know your thoughts!

In the past 2 years i have put about 7000 into this truck (does include new trans all new front end and rearend) so i am married to it now, but seems mechanic is having tuff time with this problem, and do not want to bother him with it anymore!

WTS Light? - do you get it when you first roll-on the key?

Tach Movement? - does the tach needle move up slightly when cranking?

Fuel refilling filter housing? Tank below 1/4?

Is it cranking fast enough? - it won't even TRY to start if cranking really slowly.

Is your truck "chipped"? If so, remove it as a Test.

Yes the Wts light does come on
and the tach does move
there is some fuel in filter housing, but wonder if there is enough

the truck has not been chipped for some time

Just put in new starter and batteries!
should crank over fast enough!

wondering how i can check to see if there is good enough fuel preasure?

[NoRalPh]

For pressure, you'd need to connect a gauge on the fuelbowl (there's a port). You might also look for how quickly it's refilling too. If you empty the bowl with the water drain you can judge if it's refilling well.

wondering what kind of fuel preasure i should have at the fuel bowl?

[NoRalPh]

The electric fuel pump (you don't say if you're an "early or late" 99) should produce over 50lbs of pressure. This is regulated by a spring & seat at the top left of the filter housing at the point the return line exits (FPR). It too could have a clogged screen or other problem.

Other delivery issues consist of plugged screens in the tank, cracked pick-up (running you out of fuel at 1/4 tank), bad pump, bad suction line to the tank, plugged filter, stuff like that...

not sure if truck is early or late 99!

THANK YOU EVERYONE FOR INFO

Please keep it coming!

Have decided it is not a glow plug issue!

[NoRalPh]

At these temps, the Glow Plugs shouldn't be an issue...

Look on the door pillar for the sticker with a "build date". Before 12/98 is an early 99. After that build date is a late 99.

what is the difference between early and late 99
