OK kids, she's home safe and sound. We're talking the ultimate embarassment, being towed by a rice burner (well, at least it was MY rice burner). But having a 930 towed with your basic 3000GT Mitsu....well, to make things worse I got more "cool dooood" nods from onlookers than I get when the Porsche is running! Go figure. Oh, and kudos to my lovely wife. She's become a pro all these years at doing the tow thing, rescuing her husband and his silly toys once again.
So, went through the littany of checks. Grounding the boost sensor, checking for power at the fuel pump fuse, swapping out the yellow relay with your basic horn relay, shorting out between relay pin 30 and 87A....nothing caused the pumps to run. But once...and only briefly, when pulling and re-inserting the yellow relay, did I get momentary pump action. So, I took the cover off the relay and didn't see any obvious corrosion but re-soldered only the five pins anyway. Plugged her in and nothing. Then, plugger her in again and we're off to the races! So, once again an intermittent electrical problem has basically solved itself and left me not feeling very secure. Me thinks it may be time for a new yellow. Or, I've got a probem with the relay socket itself and a major PITA to get beneath the mounting plate to check it all out.
By the way, shorting out between pin 30 and 87A - or 87 for that matter - didn't work. But, short out between 87 and 87A and the pumps will run. Either I've got weird stuff going on, or previous posts on which pins to short out are incorrect. And plugging in a standard round relay does not work....in my case anyway. Hmmmm....I think I'll just leave the car in the garage forever (or keep a short piece of wire to short across the pins and make her run in a pinch).
Any comments and/or ideas are always welcomed. For some reason I'm not fully convinced it's the yellow OB relay.
