GPR problems

So I believe my glow plug relay has been out for a while and by 'a while' I mean at least 8 months. I replaced my glow plugs 7 months ago thinking they were the problem, but that didn't help much, I figured it was just normal to have hard starts all year round hahaha (sarcasm) I ordered the stancor relay and I am installing it this weekend. Will my glow plugs be okay? Or will I have to replace those? Thank you for the info!

Most likely, if your relay has been inop, it hasn't been energizing the plugs so they're fine. But like with any such electrical issue, it's cheaper to test than to throw parts at it. A voltmeter costs about as much as one glow plug. Although a Stancor is a good choice, it's still advised to test your existing relay, and test the plugs and wiring, so you know exactly what effect the new relay will have, rather than just going on hope.

I tested the relay just last night. It was fried. Although, my 'wait to start' light has been coming on/off. Is that normal even though it is fried? Thanks for your input!

The WTS light has nothing to do with the glow plugs or relay. If the light goes on for 8-10 seconds then goes off and stays off, that's normal.

That's what it was doing but it was about 12-15 seconds so I figured it was weak and then last night I went to test it and it was done. My truck has always started hard and idled rough. I am hoping this this stancor fixes it!

When it's real cold, it's not unusual to see the WTS for that long. Again, it doesn't reflect on the glow plug circuit at all. You'll be happy with the Stancor.

Ya I figured that, but every time I got in and started my truck, it sounded like it was missing some cylinders. I just got new injectors. I don't know, I will come back and post when I install the Stancor and let you know if the problem is fixed! Thank you!
