My friend has a 89 740 non turbo 2.3 that he drove into a flooded street then died. After sitting to dry for a few hours started and drove it home and died 100 feet from his driveway. It will start if it sits for a few hours but will die after 20 - 30 seconds and not restart. Fuel pumps not running and the fuel pump relay, if I have the right one, is not clicking. They are labeled J and K, J clicks with the key in the run position but K does not click even while cranking. I swapped the relays with no change, J clicks, K no click. I jumpered 87b to 30 and still no start or fuel pumps. Has good spark, any ideas what this could be I drive a 240 am not used to the 740 different wiring and relays.
