Default Re: Injector Leak-off Test

Well, with the engine warmed up about 3/4 of the way I ran the test and had very similar amounts from each injector, 1/2 to 5/8" , the engine did cough a couple times as I was cranking, but certainly didn't run.

My van always cranks briefly when I start it, and a couple of times when it was hot out and I had been running on the highway it took 3-4 seconds of cranking before it fired up so something needs some attention it seems...

If 1.5" of fuel in one line indicates a bad injector which results in long cranking periods when the engine is hot wouldn't 3" combined from all 5 injectors mean result in the same long cranking periods?

Here is a pic from my test, I'm a little puzzled by the different color of the fuel from #2 and #5 as well.
