Can anyone tell me where the fuel pump relay is located on a 1994 100s wagon 2.8l vin WAUCK84A9RN? I`ve searched both footwells under the hood on the drivers side and have found several relays but none marked fuel pump. My car will crank, but no start. CEL is on. I disconnected the battery for a couple of days, reconnected it and it started and ran well. I shut the car off and no restart. After checking several wiring diagrams and some diagnosing I believe it`s the fuel pump relay...but I can`t find it
Awsome! Thank you! Checked it out, and my relay is under the steering wheel as you pointed out.Of course it`s a wierd relay and I don`t have a spare. I ran 12v to the post on the bottom of the connector, and the car started. But once again, after shutting off no restart. I do not have power to the fuel pump fuse, so I still think fuel pump relay. Any other ideas, I`m all out?
In your picture you`ll see each relay has a terminal below it. They all seem to have b+ with the key on except my fuel pump relay. I gave it b+ from a jumper wire and the car started. my relay has pins 87,87a,86,30, and t(which is a small terminal)the number on the top of the relay is 208. It looks like connecting 87 and 87a to 30 should bypass the relay as well as connecting 86 to t. It seems as everyone of these cars are different. I`m having a lot of trouble getting the correct wiring diagram.
Re: Wiring diagram, eh? Ask and ye shall receive ---->
Wow! You`re good! Well I bypassed the fuel pump relay and no start. This all started after the engine was powerwashed. I then drove it later in the day no problems. Parked at home and the next day no start. Hooked up to VAG got a code for cam sensor found no power to cam sensor, crank sensor, ignition pack, or injectors. The wiring diagrams I had here led me to the fuel pump relay. I checked the fuse for the fuel pump it had no power. Now it does and we still have no start? I pulled the battery to charge it, a few days later put it back in and the car started. I need to charge the battery again now at 10.23v dropping to 7.72 while cranking.
Thank you for all of your help!
