The Dangers of the 3-Legged DME Relay
im sort of confused about this topic, i know it is a good fail safe to get you a short distance in an emergency.
but what are you risks you are taking, i heard something about fuel lines bursting causing engine fires, if thats true, what else?

So long as the car is running there is no difference. Plug it in and leave it on 20 year old fuel lines and you might get a leak.
An easier field expidient method for a dead DME relay is to remove the cover, and wedge some folded up paper to force the contacts. Helluva lot asier then monkeying around shorting the pins with wire and all that.

Car won't keep running bt the Fuel Pump will.
Both are only a field expedient method to get home and replace the relay that should have been in your glove box.

Use pin #86 rather than #30. #86 is switched via the ignition. Gives some margin of protection. Still for $20 you should replace the DME relay.

the dme relay in my glove box is the 3 legged jumper, i have a new one in use right now [QUOTE]SoCal Driver Use pin #86 rather than #30. #86 is switched via the ignition.

Still for $20 you should replace the DME relay. i think im going to change my jumper relay to that, so just switch the wire connected from #30 to #86? .......i hate the dme relay i decided  seems like theres no possible way to surpass it safely

As I've reported; I've only replaced mine ONE TIME in twenty years of ownership.
I wish a lot of things didn't wear out.
