I've been watching the recent "HELP! My car won't start" thread, with the hope I'd figure out my problem. I didn't. I've posted this on two other Volvo forums and got 1 reply to check something, which wasn't the problem. If you can solve this one, you'll forever be a genius in my book.

I have an '89 760 with 235k. About 3 weeks ago I pressure washed the engine to try and find an oil leak. Afterwards, the car started and ran fine for a couple hours. I got home, shut it off, and went to move it 10 minutes later and it wouldn't start. I've found there to be no spark, and I have determined this using my timing light.

I have a friend with an identical car, and we started swapping parts. I swapped the ignition module, the distributor, the coil, and the radio suppression relay, one at a time until eventually all of those parts from my car were on his car, and his parts on mine. In each case his car still ran, and mine wouldn't.

I can hear the fuel pump working when I crank the car, and when I pulled the plugs they were fuel soaked. Aside from that, they had no indication of anything but normal combustion. I also checked the injector connections with a noid light and they're all getting a signal. With the key in the "ON" position I have 12v at the coil, and I've checked every fuse. They were all good.

All I can think of now is a crank sensor, but for the life of me I can't find it. Autozone has a listing for one, as do several online suppliers I use, but I've looked all over the bellhousing and the crank pulley in front and can't find a sensor. Is this one of those odd years where they hid it somewhere?

Any suggestions?

Thanks
