start up problem

[96whitestroker]

so i changed my glow plugs and my glow plug relay isnt bad and my truck wont start in the cold if it sits for more tan an hour. unless i plug it in i have to shoot it with either. any body got any ideas/

[JSchuricht]

Are you getting power to the glow plugs? What's the voltage dropping down to when you turn the key to run?

[96whitestroker]

its at the n in normal

[wyoming]

check your batteries too if you have a bad cell or bad connection on one of the batteries, it will show ok voltage but you wont have the amps you need to run the glow plugs right

Normally the volt meter goes to where 10V should be on the gauge. Not to sound like an *** how do you know the GP relay/silionoid is bad?

[96whitestroker]

changed with a new one still did the same thing. and also just put in new batteries and stater. could b alternator maybe? idk that just came to my mind.

Does it crank slow?

first thing is that ether. Its like crack to these motors and if you have been using it it may have blown out your brand new glow plugs.
