Need Ideas??!!

I know its been damn cold out but my truck has been having troubles starting up. I changed the fuel filter. But some times the truck has to be plugged in for a while for it to start. Some times it gives me some crap when i go to fire her up even after its been plugged in all night. Some times when i park it for a couple hours after i have to cycle the plugs a couple times and cranked it twice before it will fire up. I dont know i might be crazy but the truck didnt act like this last year hell even when the winter first came on it didnt act like this.

Any ideas would be great thanks for reading idk im just frustrated with this!!

Glow plug relay or glow plugs would be my guess.

As the glowplugs begin to fail they draw more current. This can be hard on the under valve cover harnesses and valve covers electrical connectors, which causes them to melt.

If you have some time, pull valve covers and inspect for melted electrical harness at the place the harnesses plug into the valve cover gaskets. You can also test glowplugs by removing them and hooking them up to the battery.

When the glowplugs are failing and using more current, it can cause low voltage for the engine control unit.

On our 1996, there were only three glow plugs still working. Last year I replaced them all and it starts on the first crank.

Not yet been kinda busy lately and havent even been driving her. Im really leaning towards needing new glow plugs so i might just say heck with it and change em. The relay still clicks pretty loud. How would i know if it went bad?

The glow plugs will light for over 1 minute after the wait to start light goes out. No need in cyclying the key on and off. give it a good 45 seconds after the wait to start light goes out then try to start it.

If the gp's are bad change em quick like stated above or they will eventually melt the under cover harness. I had 2 plugs go bad and it melted the harness under the valve cover. Once that happens you get all kinds of funky things that happen. Been there .
