M50 in an 87

[White325is]

I got an 87 325es in the garage. Right now Im not getting inj pulse at all.
When the key is in the on position I got 12.3 volts. When cranking I have 10.9..

CPS is saying I have 520 ohms....

make sure your pcm is grounded well. the injectors hold closed at voltage and the "on" pulse is from the pcm grounding that injector. you wouln't be able to see it with a dmm so you need to use an oscilloscope to check them.
good luck
