So the pink/black wire is getting 11.98 volts. Batteries together measured 24.5 and alone they were good. Don't have a min/max feature on my meter, and I haven't had a chance to bring them in. Was I supposed to take the green wire off the injector while the pink/black wire was grounded or...

Alright, so I don't really know where to go from here, so I plan on doing the resistor bypass to the front battery with a 120 amp mega fuse, and 8 ga wire (cuz why not right?). Then I'll give it another multimeter test. Anyone have any opinions about my temp switch not having the optimal 800...

Okay, it went back to 24 volts. Didn't have to give it a whack either. Maybe I metered wrong the first time.

Again, many thanks yall. So, I will want to do another resistance test or actually remove each plug to check for swelling/damage?

So I measured the voltage between main gp relay terminals (one prong on orange lead, and one on red lead) and it was around 24 volts with the car off and cold. I'm assuming I was supposed to do this with the controller card in? After I turned the ignition to "run" it went to 0 volts. Then...

24.8 volts :???:

Thanks for all the help yall. So, I'm pretty confident I've tested this correctly with my multimeter. I've attached a picture of the TM's testing procedure with the results I'm getting in red. The GP relay test seems to be good, though. (there is no voltage getting to the orange lead on...

In the TM instructions for testing all the module wires it only tells you to disconnect pink injector pump wire and pull out the controller card...nothing about disconnecting batteries. Here's what I'm getting as of now: Purple/white: 7 volts light blue: gp relay does energize dark blue...

So for the resistance am I connecting the red lead to the module terminal/wire and the black lead to the ground? If I'm getting readings that aren't correct should I get a new card or move to a different area? From the TM is sounds like module is the first place to start/replace. My main issue...

Thanks much ALECS!

Hey guys, I feel like I've done enough searching so I'm just gonna ask... There are a few simple voltimeter actions listed in the instructions for testing the GPM that I don't grasp 100%. Does anyone mind elaborating on phrases like "Approximately 12.0 volts at wire","jump wire to...

haha yeah, i'm very familiar. just thought i'd shortcut it.

It taking more than 10 seconds for the wait light to come off. Then instead of hearing the relay turn off quickly (i think that's what makes that sound?) it makes a lonnnng drawn out noise. Ever witnessed that?

it starts to but then that loud machine gun sound starts to overpower it. i think it stops turning over when that happens

batteries were tested and checked all connections on the batteries

I've combed the hard starting cucv threads, but I couldn't find any mention of this sound I'm hearing when cranking over my M1009. It's always been hard to start in the cold (even after new glowplugs), but now when I turn it over it makes a sort of machine gun type sound. Sounds like its...

yeah, now i can keep putting off the real problem behind its lousy starts aua ..at least til its warmer

started like a friggin champ!!

thanks guys. i'll let you know how she starts in the morning!
