1993 Buick Skylark GS 3.3L - Location of fuel pump relay
I have not been able to determine the location of the fuel pump relay on this car. The 8th character of the VIN is "N". I have searched under the dash near the fuse box and also on the firewall, but have not located it. The sketches I found online do not seem to show anything that is actually on the car. Any help will be greatly appreciated.
Great question. Before I removed the tank and changed the fuel pump motor and filters, I had tried to run the fuel pump with the fuel pump priming connection (the red wire coming out of the wiring harness near the driver side shock tower). When I had applied + battery voltage to this wire, I was getting a spark when I made contact with my jumper wire and the + battery terminal. However, the pump motor was not running, presumably because it was siezed up. At some point I quit getting a spark when I made the connection. I have now replaced the fuel pump motor and it does run for two seconds when I turn the key, but it does not run when I connect battery voltage to the primer wire. I checked all the fuses and they are good. So I suspect I burned out the relay trying to run a siezed fuel pump motor with the fuel pump primer connection.
A Q&A I found on Fixya said it was in the middle of the firewall (engine compartment side). I took a photo in case that might help.
I should have said passenger side instead of curbside because if one drives on the left side of the road, there is a curb there too.
Check right behind the passenger side headlamp assy. They are usually hanging there.
