It is very possible that there should be a resitance.

 

Why would there be resistance on a ground? As far as I know there should be no resitriction to cause resistance between a wire and ground... do you have a reason for thinking this?

If there is a short somewhere you can get resistance to the grounds depending on where the short is.

 

If I disconnect the battery, it would remove the positive power... then I could retest the grounds, and if I don't have resistance... then I have a short... if I still have resistance, then I robably just have a corroded ground (cause all three grounds read exactly the same...)... does that sound about right?

Thanks

Ok... so I found out the grounds for the computer were not the only grounds showing resistance... the whole car was having a resistance from ground to ground...

Once I disconnected the positive battery cable... I now have NO resistance between any ground points...

So this means I have a short somewhere... I just wish I knew where to start....

Can this create a no saprk, no injector pulse condition though....?

Man this car has been hell....

For a cicut to have a small amount of resistance is normal. You could be reading through a resistor, or capacitor or somethin like that.

 

Yes, but I am even getting resistance directly going from negative battery to direct motor ground. And negative battery to direct body. Once the positive battery cable is removed, there is not a bit of resistance to DIRECT grounds....

did you jump the asd relay to see if the car runs/
if so you have to see why the asd relay is not working

 

I have been a technician for 6 years, and just so you know wire itself has resistance. Each connection has resistance. It just depends on how much . If they are all similiar then they are fine. You also have to understand that the longer the wire the more resistance it will have. If you measure a foot long piece of wire, then a 2 foot piece, the 2 foot piece should be slightly higher . I would check to see if you get power at the injectors. If not check the next component behind them, maybe the relay or fuse. Do the same for the ignition. Obviously if you work your way back to the pcm and there is no signal going to the two circuits when they should have signal then you know your problem is the pcm.

 

all 4 injestors won't go bad at the same time though, the ignition is generally not an intermitant problem. I still stick with its the PCM.
