87 740 B230f No Start

ICQ>

I posted this problem a couple of weeks ago. I have a very intermittent nostartcondition. It happens every couple of months. The engine turns over but will not start. Getting fuel to the fuel rail, spark to the plugs. I pulled one of the plugs and found it dry. During this time the air control valve was not on. When the engine finaly started I noticed the air control valve started ant then the engine ran. Dont know if this means anything. Cleaned all connections at the engine wiring harness a couple of weeks ago, this seems not to be the problem. Any other ideas? Ready to retire this monster.

Thanks, Lou

that is the typical symptom of a failed auxiliary fuel relay (on shock/strut housing in engine bay, black with 4 wire connector), except that injectors don't work. How are you determining injectors are working?
