The fuel pump relay is Part No. part # 003 545 25 05
I am not sure now but this should be located under the hood by the fuse boxes. If not try locating it close to the firewall under the wiper motor. It is a black box about 2.5in x 3.5 in x 1-1/4 in. There should be around 10 pins for the connector (line of 6 and a line of 4 pins). Just pull the unitup to disconnect. Let me know if you need a used one.
Thanks.

I found it. it is connectect to the firewall and the demenssions are correct. This was the issue why I was not getting power to the fuel pump. The pins needed to be clean and the receiving side needed to be tightened for the module pins. Now all is fine and the motors are humming away. Thanks

I can hear the pumps come on while standing at the engine compartment, I also felt them as well. Still no gas to the engine (pulled gas supply line at intake to veiw) Cranking or not still no gas?
