Cold weather issue/glow plug warm up.

[Randy646]

Last week I took a 1986 HMMWV for a drive everything ran fine, got a oil change, washed it and no problems. The weather temp dropped to about 11 degrees a few nights ago but its only 30 when I tried to start it. We also got our first snow today. So I go out to try and start it. The wait light will not go off. I am guessing the glow plugs are not heating up right. I replaced the PCB box last year, But the glow plugs have not been replaced for a long time. I gave up on the starting it for tonight as I felt I was wearing down the battery.


Any ideas on what I need to do? Thanks
