I’m trying to find out more about the leak of test just doing the cranking for 10 seconds version rather than letting it actually start. Do I have to unplug a sensor or something so that it just cranks and won’t turn over?

I'm very interested in this test.
While waiting answer to your question, i have a request to you: what's the diameter of the tube you used in the test? Definitely, i'm going to buy it to try.
Very very long starts are desappear with new cps, but i need 3 or 4 turns to start, yet.

Here are the instructions I followed from sprinter source. I unplugged the cam sensor and counted down 10 seconds, but mine was so bad that it wouldn't start anyway.

1. Purchase 3/8" ID clear tube from home depot- 2ft

2. Cut it in 4" lengths.

3. Take injector cover off

4. Pull clips off of each of the return fittings on top of the injectors

5. DON'T LOOSE THEM (I keep a clean peanut butter jar with lid around just for this purpose- they store the cut sections of tubing in them when not holding the clips)

6. Carefully pull the return line plastic fittings up and off the injectors (they can break- I've never broken one, but I have read on the forum that the only source for them is Andy)

7. Unplug the Cam sensor (next to injector #5)

8. Fit one tube over each injector head

9. Using a vice grip and cardboard, pinch the fuel return line BEHIND the "T" for #5 injectorfuel can come backwards out the fittings and you can have a mess on your hands.

10. Crank the engine for a full 10 seconds- it won't start because you have your cam sensor unplugged.

11. Check for one or more tubes that are overly full. Andy told me that 2.5ml or more fuel in the tube meant that it was time to replace the injector. I just measured this and in that 3/8" tube on the injector, that would be right at 1 and 1/2" or 37mm for the rest of the world.

Ok somewhere I went wrong but do my result still count?
I bought 3/8ID tube as instructed but it actually required 1/4” ID so I used some water line I had kicking around
I unplugged the cam sensor. But the Jeep started anyway. What didn’t I unplug?? (See picture)
Husband cranked and we almost got to 10 second shot before it surprisingly started.
Here’s my video.

So I have a lot of diesel in 3 tubes but given that it started, are the results true?

Hi tango.
I apologize you for any inconvenience. I need to make you a question about pump sensor.
That reference (#0061536528) is for number #1 sensor or #2?
Is it easy for change? How did it?
Thanks a lot.
