Buzz test sequence??

What sequence does the buzz test use while buzzing the injectors? Mine seems to jump around.

The sequence is 1-2-3-4-5-6-7-8. The cylinders are 2-4-6-8 front to back on the driver side, and 1-3-5-7 front to back on the pass. side.

The buzz test will fire every injector then it will jump around from bank to bank.

Okay thanks- I hear the second buzz (after they all buzz together ) sounds flat, but it's on the passenger side. Have to get the stethoscope out.

The individual injectors are rather quiet it seems like. But if something is way obvious then it may warrant further investigation.

I turned the radio off and got real quiet- the second buzz was really faint, it was the drivers front. Seems weird I keep getting the P01271- number one cylinder circuit open. Tomorrow I will pull that side valve cover off, I got a few injectors used today.
Thanks again!

Okay- I pulled out old number two injector and whatdoyaknow- looking at the plug end I only saw one terminal, the yellow wire was pulled through. It must have been making just enough contact to pass the continuity check but not enough to fire the injector properly. I fixed the wire and installed the fresh injector anyway since I had it.
I re-ran the buss test, all 8 sound consistant, the truck runs sweet, but the p1271 code is still there- weird....
Thanks for all the support!
