I rinsed my 1986 volvo 240 dl enigine while the car was running with a high pressure water hose trying to find a transmission leak. I replaced spark plugs, distributor cap and rotor and my car will start for a couple of seconds and then stop running. Does anyone have a suggestion were to look or what to look for next.

    Check for diagnostic trouble codes: http://volvospeed.com/CheckEngine.php
    Here are all the codes: http://volvospeed.com/vs_forum/index.php/topic/47502-dtc-information/
    The main wiring harnesses for these engines had a tendency to deteriorate, and if you see the insulation coming off the harness (especially under the intake manifold) you may have got water in there and caused the wires to short out.
    Post any codes you pull out and I can give you some more info.

    it could be that you got water in the wires that attach to the mass air flow sensor thats in-line from the airbox to the air intake. unplug the mass air flow sensor and see if it's wet. it may be that the rubber sheathing to the clip it cracked and water got in. if it is then use electrical tape to make sure water doesnt get in. good luck
