Thanks for the response. I clipped the meter leads on where the pump leads connect on top of the pump assembly, so what you're saying is possible.

This morning I tried to start it again, but it wouldn't go. I disconnected the MAF and it started and ran reasonably smooth (didn't drive it). To be sure, I reconnected the MAF and it wouldn't start again. I repeated this 3 times with the same results, so I'm assuming it's the MAF. Geeze I hope this is it.

I also tested the Cam position sensor (CPS), and it tested ok. I did this by ohming pin 1 to ground and got < 1 ohm. With the CPS sensor and shadow plate removed, I connected meter leads to pin 2 and ground, turned on the ignition and moved the show plate in and out of the hall sensor gap. I got a 0 and 12 VDC pulse. This tells me it's switching.

For who that might need one in the future, someone else posted this link to the hall switch http://www.newark.com/honeywell-s-c/2av54/hall-effect-magnetic-sensor/dp/96F1986. Here is the link discussing it on the Brickboard. http://www.brickboard.com/AWD/volvo/1311340/850/camshaft_sensor_repair_information.html
