Hello recently, I disconnected such a relay from gas or gasoline, I do not know what it is because I cleaned it and I do not know which wire was to which contact and I connected it as any and there was a problem my golf 3 does not want to start on gas? will help someone I will be very grateful...

The wires that control the relay from the gas installation, most often blue and black (ground), are connected respectively 86 and 85. The wires attached to the car's installation, disconnecting the electricity from the injector, are connected to 30 and 87a in the middle of the relay. Contact 87 remains free.

Examine the bundles, 2 wires (usually yellow in gas installation kits) go to the injector, you have to connect them at 30 and 87a.

You did not think how you were doing, now do as you see fit .... Here on the Forum we can predict, and in my opinion you should ask an electromechanic for help. It is difficult to deal with it at a distance.

Well, unfortunately, I have a lesson that you have to watch or write down when something disconnects, but the electromechanic will probably want what money, maybe someone will have the same relay in golf 3, he will tell me

that is, 30 and 87a current blue wires and 86 and 85 are black ground, so should I connect ??

Thank you, the problem is fixed
