Hard to Start
Hi All,
New Batteries, New Starter and New fuel filter, but I'm right back to where I started. I needed batteries and I needed the fuel filter, but I probably caused the starter failure by cranking to long. Nevertheless, I installed a new one.
Anyway, it sort of acts like it wants to start, but won't. Smoke rolls out the tail pipe. This is when it's cold. It will probably start when it warms up today, if it does get in the fifties.
So...................now I'm thinking the glow plugs or relay. Isn't that the logical thinking at this point?
I was hoping it might have been the fuel filter, but no such luck.
Why the smoke? Does that point to something else?
Many thanks.

When you go to start it cold, try jumping the two big posts on the GP relay for a minute or so...then try to start it. If it starts easier, you GPR is shot and needs replacement. If it doesn't start easier, then ohm out the glow plugs...if one proves bad, replace them all. The smoke is unburned fuel...the engine hasn't enough heat in the cylinders to fire the fuel charge and it is coming out as unburned fuel gases (white smoke).
"..ohm out the glow plugs..."........???
How many glow plugs are there? Where are they located?

Thanks for the video.
At the end of the video, the pointers said something about an engine heater.
My unit is a California truck and I don't think it has an engine heater. If it did, and it worked, I wouldn't have any starting problems.
I didn't totally understand your testing in the video.
You ground to your alternator/bracket. Ok. Then do you have to stick a lead into the hot wires of glow plugs?
I guess I don't understand all I know about this

If it is not there, someone removed it and you could replace it. It is not the way to fix your problem. You have your DMM set at ohm setting and you probe the connection to get the readings for the glowplugs.

You do have a block heater...look near the oil filter/oil cooler for a heavy wire and follow it to the front of your truck.
If it is not there, someone removed it and you could replace it. It is not the way to fix your problem. You have your DMM set at ohm setting and you probe the connection to get the readings for the glowplugs.

What I meant about the heater...................when it's warm, I don't need the glow plugs for it to start. Well, I'm sure the may work then too, but they don't have much of a chance to "get glowing"
.I'm gonna check for that heater cord. The truck is just as it came from the dealer in 2001.
Thanks.

I used a screwdriver to touch both large posts for a minute or so.
