Cost of GPR

[Fordman247365]

ok guys i have been reading on here for awhile and have narrowed some things down, here is the basics. i have a 96 F-350 4x4 and it is F'in cold where i am at but last summer i started to have to either use ether or plug my truck in to start it..when it was like 70 degrees. now even with it plugged in it wont start without ether(now below zero ) and as i have read i need either the GPR or new GP's. so the first of my ?'s is where can i get a new GPR (since everyone says to change this first) that is cheaper than the $90 @#%*& *@#%&* that NAPA wants for it. For all the glow plugs is only $100 and they want 90 for a simple relay. anyway after i get that done will it fix this, after i start the truck, i always let it warm up for a bit, it 'misses' for a mile or 2 then picks up the missing cylinders and i have all the power in the world and runs fine for the day then repeat after full cooldown. i have 412,000 miles on it (approx 160,000 on engine) and want to keep her runnin strong. any help with cheaper parts would be great. thx in advance

Instead of throwing parts at it before you know exactly what is going/gone bad,

i'd check the GPR and the GP's.

Then you will know what exactly to replace

here ya go

you can get a GPR at oreilly's for 70 or on ebay for 30

I can tell this, the WTS light stays on like everything is working but you can hear the relay click on and almost immediately click off even tho the WTS light is still on when its cold.

WTS light is just a dummy light more or less. It has no correlation to how long the glow plugs stay on.

that they are


My recommendation would be to test the glow plug relay as it says to do so in the thread i posted above,

and then if your GPR is indeed bad, i would replace it with the stancor model.

Cheaper is not a good thing in this case. You don't want to have to replace it again next winter do you?

yeah i hear ya, i have the ol lady's credit card so cost dont much matter, but i havent heard anything good about NAPA's GPR and the STANCOR one is half the price of the NAPA one

The Stancor one is alot more heavy duty. Its made to handle the amp draw the these glow plugs use.

Napa unit is not bad, just it isn't as good as the Stancor from what i've been told.

I hate to be "that guy" but ether is bad stuff....

WD40 or a rag soaked in gas is a better option
