[V8] Meters n diagnostics

[Scott Justusson]

 Fluke meters are some of the best, I own 2, but haven't used either in ages...  90% of my work with a meter is automotive, so the the best tool you can buy is the powerprobe
www.powerprobe.com

I had the PP2, and now have the PP3 Master kit, and what it does for electrical diagnostics (esp on a v8) will make a fluke seem like doing neurosurgery with an ax.  The PP4 looks like even a more user friendly unit.  My PP3 master kit gives 45 feet of cable, which is great for moving about a v8 front to back.  Having 12v available at the push of a button is great for relay test and direct power to various devices.  

When I had my shop, the PP was absolutely the best audi tool I ever bought.  To this day, it makes really fast work of 12v electrical diagnostics.

The fluke 77 is a nice DVM.Pretty much any Fluke is good. They don't make junk. Beckman is also good, Tektronix, etc. there are of course lots of cheap Chinese junk out there. You get what you pay for. On your problem- it sounds like the fuel pump is not commanded to turn on, or you have a fuse blown somewhere. The ecu won't command it on unless it sees activity on the timing sensor. That signal is hard to see without an oscilloscope but it should throw a code.Sent from my iPhone> On Feb 22, 2016, at 9:27 PM, "toml99 at todomundo.com" <toml99 at todomundo.com> wrote:> > It's not the relay....swapped that for the working one in Lago last year.  Pump doesn't work with jumper either.  Pump worked when I hooked up 12v in trunk(sprayed me down when cracked line at regulator, but didn't put a gauge on it)  Need to get it somewhere I can mess with it.  Already went thru all the tests in the book which led me to bad wire to/from ecu(also verified it's good) since I don't have spark either  (only thing at time I hadn't verified was pin).......New ignition switch was also tested at time also.  Need to get a nicer voltmeter with longer leads and recheck everything.  Anyone care to rave about their voltmeter?  Borrowed a Fluke 77 and thinking of upgrading to something better than a nice $40 one.  The last one I had had a beep for continuity which I like.  Smoked my voltmeter awhile back being plugged into the wrong unfused lead connector while trying to find the voltage draw(on the 5-speed which also is leading me to a bad wire somewhere).  HATE dealing with wiring in a car, and out of all the cars I've owned in my life, the V8 wins the award for most issues.  Saw a friend's old '50 Chevy 1 ton and it had a total of 7 fuse holders in
