Pink should be 12V. Maybe you used the continuity on your meter while it had power? I know some meters will shower power as a short. What cam has it got? original stock or an aftermarket one? Definitely a short to ground on the pink wire. Was definitely set to resistance. Also no power as the senso...

pink wire on the oxy sensor plugs, is this supposed to have a short to ground???

I've had 2 engines with a miss that was low compression. One was a 5L that had burnt out a valve and bent a few pushrods. Another was a 4L Ford that the rear piston wore into the bore sideway somehow and there was something like a 5-6mm clearance on the right side of the bore with the left side of ...

Using my phone with small characters so forgive me if I double with info. I think from memory your ecu can do a power balance test which will identify the offending cylinder. From my experience and what you say it's a definite miss most likely mechanical. Ive been trying to find some form of power ...

Im still doing my head about this, I noticed the wires on the injectors were split and frayed so i reterminated them with new plugs. Didnt fix the issue. I also checked the timing was set up fine. I earthed the O2 sensor and heater circuit to the back of the head (only the drivers side to see if it ...

Yep the one on the water outlet is the ground for the drivers oxy. all tested out fine.
i thought id try and test the grounds on my injector plugs, couldnt get a reading.
just want to confirm if my thoughts are correct, 1 wire is an earth and the other is signal?

In the thread I linked there is a PDF that shows a picture for the earth below the DFI module. its got a pic of a buick i think. surely im not going crazy. the only wiring i have goes from the cam sensor, to the CAS. then down under to the knock sensor. i cant find anything down there resembling an...

It's probably worth having a look at this. https://pcmhacking.net/forums/viewtopic.php?f=32&t=5444&hilit=VS+O2+sensor There are more earth points under the DFI module which apparently include the earth point for one of the sensors. The link also has a picture of the patch loom I had on the ...

Have you done a compression test? just checked her out, seems fine to me. engine was pretty much cold. Also thread on my gauge was the wrong size and only goes in a couple threads. probably why theres such variation 1- 135 137.5 137.5 3-145 150 152.5 137.5 140 5-137.5 137.5 137.5 2 132.5 134 134 4-...

Have you used a VS wiring loom? The fault is in the loom with a shared earth for both the heater circuit and sensor circuit. Simply changing the sensor doesn't fix the issue. If you are happy to sacrifice a O2 sensor you can cut the earth wire for the heater circuit (effectively turning it into a 2...
