working on a 200 HPDI for a friend, have a question

[captpete13]

the smaller hpdi's only put out about 700 psi. The bigger ones with twin pumps put out closer to 1000. Try spraying fuel in the throttles. Maybe you have water in your fuel. Injector driver failure will not show on the laptop. you are going to have to check for voltage at the injector. I forget how much voltage off the top of my head. But I want to say it's somewhere around 30vdc at each injector.
