M1009 Glow Plugs

[bgfd2216]

I have a 1984 M1009 I have replaced the glow plugs with new ones and it still will not start. I have tested to see if I any volts at the glow plugs and I am not showing any. Anyone have any ideas?

First do a advance search on this problem then check this link for the TM-20/34
In the meantime check out the glowplug relay see if you have power on the top lug then see if you have pover at the pink wire on the injection pump with the key on. then go from there.

Welcome to the site and follow the above link to get the manuals. The -20 has a huge 70 odd page trouble shooting section. It will walk you through how to check every part of what is causing your troubles.

Just help out, they are talking about the TM 9-2320-289-20 and TM 9-2320-289-34 Technical Manuals. Available for free at JATonka's website.

There are multiple pieces to the GP system puzzle. You have to check that each one of them are working properly.

There is the:
fuse
fusable links
GP relay
GP Controler card
Temp switch in the engine head
all the associated wiring.
and the biggest of all

Is the truck Stock or has it been "modified"

Is the glow plug relay under the dash?

 

[doghead]

No, it is on the firewall, under the hood.

I am not having any luck finding the glow plug relay on the firewall I have found the glow plug card under the dash but can not find the relay.

Not having the relay could be the problem.
