Does anyone have a chart or listing of the proper fuel pressures for the different model 9k's? I think it would probably help out a few people. I am specifically in need of the normal pressure for an 88 9000s.

Trying to solve a "air/fuel mixture too rich while driving" code. I recently replaced the stock walbro pump with a bosch pump from an 89 9kt and the car ran great for a week. The incident that led up to this failure to run was my bathing the engine in water after a quick degrease. I guess I could have shorted a sensor or some other electrical component, but which? The car starts but stalls itslef out after about 10 seconds. The fuel pressure regulator is fine,(I've tried three differnt ones) as are the air mass meter and AIC valve(have an extra of each). New fuel filter and correctly gapped plugs. My only other guess would be the O2 sensor or the ECU...any other insight would be greatly appreciated.

thanks,

-Mark
