help needed truck wont start
I am out of ideas, I have tried 3 different pmd's, checked all the fuses, have fuel from the t-valve. It cranks over and acts like it wants to start every couple tries but it just wont start. I am not sure what else to check. Anyone have any ideas?
|
I should add that it ran fine when i parked it last night
|
Well, a diesel needs fuel, air, pressure, and heat. If it ran fine last night and your fuel system looks good, I'd suggest checking your heat source (glow plugs, plug relay, controller).
|
i finally found the issue, when the shop fixed my exhaust they broke a ground strap, it must have been grounding out on the exhaust yesterday for it to have started. thanks for the reply
|
It's good that it was quick and simple (and free).
|
indeed
|
So that must not have been the problem, this morning it is doing the same thing. After I got it started yesterday I drove it all over the place leaving it for hours at a time and when I came back it fired right up. This morning I have the same thing, crank crank crank and white smoke out of the tail pipe but no fire. I checked the ground I fixed, its still good. So what could it be? I tested the wires going to the glow plugs and they have power.

You might want to check the condition of the CSS (crank shaft sensor) with age these tend to fall apart use AC/Delco or Napa only if replacing.

Fuel shut off solenoid clicking strongly when the key is on every time?
|
yes it is
|
i am going to plug it in tonight and see if it starts in the morning, I finally did get it running again, i plugged it in for maybe an hour and charged the batteryies back up and after just a few cranks it fired up. since then i have run it shut it off for about 3 hours and it fired right back up again. You think this is a glow plug issue, seems strange that it would just all of a sudden happen. but i guess if it fires right up in the morning after being plugged in that will tell me.
|
Glow plugs was going to be my next diagnosis,be it the controller or blown fusible links in the harness or plugs themselves?
|
ya thats what i am leaning towards, started fine this morning with it plugged in, where are all the fusible links located i could only find one
|
There are many fusible links.
Each bank for the haerness has 1 and then each glow plug wire also has it's won fusible link. You might want to buy a new harness from PT Wiring Solutions on ebay? |
