They are easy to test if you have a 12 volt or 24 volt power supply and a test light or volt meter. Here is a video showing how to test the flasher:

Trouble with our trucks and finding answers is why we all come to this site. The spark at the points is what causes the coil to “collapse” and send hi voltage to the distributor cap and plugs. Check your leads around the points and what could be touching the points. Something is causing the...

Yes, I am the Tim in the video. Delphi HFP906 is the only mechanical pump I know currently sold new that works and can deal with the biodiesel.

Exactly. I normally count to 20 while cranking, let it sit for a few minutes and repeat. Here is a video about the entire process:

If you are getting greasy white smoke then you have fuel but not enough heat to create fire. Basically anything below 156° inside the cylinder is too cold for a diesel.

It normally takes around 60-120 seconds of cranking to get air out of the injection pump.

Clogged sock, cracked hose, no fuel in tank or bad fuel pump.

The fast idle and cold start advance both have a green wire connecting to them. The pink wire as pointed out above is what turns the fuel on or off. My post in #24 is just following normal fuel filter bleeding procedures. If the engine is cranked with the pink wire connected and powered while...

Heath diesel 22 inch fan. It could be a Duramax fan, but I have never compared them. Heath Diesel severe duty fan clutch. I drove 487 miles yesterday. Late afternoon above 90°. Never spiked higher than 203° coolant temp while climbing some long steep grades on I-10 west of Kerrville.

It might be too late. But, pull your pink wire when checking the lift pump flow with the fuel filter open.

Have you removed the check valve for the return line on the IP to see if it has a bunch of little black pebbles from a disintegrating IP? Near the end of this video is what I am referring to:

The rule of thumb used to be that above 35-40 mph air from the airstream flow would keep an engine cool. It still might be true for a non turbo 6.2. However the original poster has a truck with an add on turbo, air conditioning and a transmission cooler. All of those things add heat to the...

Thank you.

How did you adjust the brakes? You should have a firm pedal that is 2-4 inches above the floor with no air in the airpack/truck air system. You wrote it has been bled twice and the brakes are adjusted. Also, that there are no leaks. At least 1 of those 3 still needs attention. Here is a video...

Thank you for the links. Any idea how to find the lock up percent and duty cycle for that fan clutch? I wasn’t able to.
