so i have a bad plug???

[stevew007]

ok i have a unmodded 99 7.3. i just went out and tested the glow plug's and the driver front prong has no reading and the rest have .3-.4 ohm.
i have zero money to have it replaced and the dealer want's $1200 to replace all plug's. someone told me that you can replace just the bad plug! is this true? what will change when i replace it? I am getting 16mpg average
crappy cold start's (when not plugged in). is this a hard job? I have a garage and tool's I just don't want to get in over my head because this is my daily driver.

To replace the glow plugs they want 1200 bucks? GOOD NIGHT!

Glow plugs are easy... remove all the valve cover bolts, remove valve covers. Pop the white wires off with your finger, and then use a 10mm 1/4" deep well socket down there and un screw them. Reinstall new, good glow plug.

one glow plug not working will not cause your problem, on a 99 model, the relay is more than likely the problem, yes the one glow polug may need to be replaced , but you have more problems, have you checked the relay at all

[stevew007]

yes i did check the relay 11 volt's just like the write-up told me

[stevew007]

so scuffy are you saying that the plug is no big deal?

[SCUFFY828]

not in my opinion, its not no there are seven more , in my opinion not even knowing the mileage of this vehicle if it cranks good when plugged in im gonna gess it has higher mileage and when does start runs rough and seems to skip, which tells me the injectors are shot and sticking when cold , i may be wrong but thats just my two pennies on your problem

[stevew007]

it's now just broke in 116.xxx mile's and it don't run ruff

[stevew007]

ok cold start's for me is below 20 deg
