ok im haveing a hard time finding that ground near the oil pressure sender
is that the one that connects on top of the engine bay fuses box, because i cleaned that to

There is only one ground, and it goes to the ICM bracket. You are not getting the ground from the cam and crank sensors? Hmm...ok, do this. Take the grey/red wire that is common to those sensors, trace it to the ICM, and ground it with a jumper wire and see what happens.
You very well could have pinched or unseated the ground wire(*) in the ICM harness.

ground has ground
sorry
should thay all have power with key on
and if the cam sensor go'* bad can that short out the crank sensors signal since thay are linked? i dont have a o-scope to test the signal but the cam sensor is the only one thats not new from store
maybe that new ICM i had was bad, i got bad luck like that,,

I believe that all should have a voltage but the ground. The source will have the higher voltage, with the return being a few volts lower. When you say "ground is ground" is that because you are reading zero volts there, or have you actually done a resistance measurement showing that it is actually at ground?

OK, good. Do you have a digital, or analog meter? As you don't have an oscilliscope, you can still check for pulses coming from the sensors with the meter. It is a lot easier to follow the bouncing needle than it is to follow changing voltages on a digital meter. Plus, they are a bit slow in responding. Measuring at the output of the sensors, see if you can see voltage changes (pulses) or if it remains steady while cranking.

ok i have
6.6 at H when key is on..jumps up n down when cranking
.04 at G when key is on jumps up when cranking
6.6 at J when key is on..jumps up n down when cranking
L has ground
M has ground
P has power
N has 10 v
