Ok. 6.5 project.
Replaced lift pump, filters, injectors etc. All good up to the bleeder. Clean flow with no air. Problem. No fuel to the injectors. Rear four injector line cracked open. Nothing. Lots of cranking but nothing.
I need a little help understanding how the injector pump works. Tips on troubleshooting etc.
The electronic DS4 IP uses the PMD for monitoring the fuel solenoid open and close times and reports it to the ECM.
IF the PMD is bad you will have a no-start condition.
All good stuff. Grounded the PCM with a wire from ground to the heat sink. Looks like this may have helped. Getting a little fuel drip at the injectors. Battery needs charging so I’ll try again tomorrow.
Take your batteries down to the local auto parts store and ask the staff to Individually Load Test them.
If one or both fail, replace them both as a matched set.
If you need to open injector lines only open the #1 line to lessen the amount of air you are introducing into the fuel system.
Most people don't realize how fast a diesel needs to spin over to crank. If you are starting to see fuel, tighten all the lines up and spin it over as fast as it will go. You say battery. Hope you mean batteries. I'd even put some jumper cables on it for a little extra ump.
