      Robflor, thanks for your help. I think I have found the main relay under the dash. There is a picture of the main relay in the link that you sent me. Looking at that picture, I was able to get the left connector off the black box fairly easily. I have tried every which way from Sunday to release the right connector but it will not come off. Of course you have to be a plastic man to get to it. It looks like it has a push tab on the top of the connector, and where the wires come out of the connector, there is a long tab the length of the connector that clicks when I squeeze it, but the connector will not come off. I tried to squeeze both tabs at the same time and ply it off with a screw driver, but no luck. I DO NOT WANT TO BREAK THE CONNECTOR. Do you know how to take this connector off?

              One more question. Do you know if the fuel pump cuts itself off when it reaches its operating fuel pressure even if the driving voltage is still applied through the fuel pump relay?

                  This is a continuation of my previous response to you. Here is what I have done so far to find the no start problem. I checked the fuel pump relay and that works fine. I put a new fuel pump in and that works find. However, I am not getting 12 volts to the make contacts of the fuel pump relay. This is the voltage that drives the fuel pump through the fuel pump relay. This voltage comes from the make contacts in the fuel pump relay part of the main relay. I cannot find the main relay in my car.

                      Thanks for your quick response. Your directions are great. Please have patience with me. The first part of your directions refer to the main relay. Here is my problem. I went to the parts store and got a main relay so I could know what I was looking for under the dash by the steering column.. I looked under the dash by the steering column and found what I thought was the main relay. However, the new main relay did not match the one I thought was the main relay in my car. The one I found in my car had two connectors. One connector had four wires going into it and the other connector had multiple wires going into it. I figure the connector with the four wire was the fuel pump relay part of the main relay. However, when I unplugged the connector it had pins while the new main relay had spade contacts. Plus the new relay was upside down and backwards to the one in the car. I searched everywhere under the dash for another black box to match the new one but I cannot find another black box that matches the new Main Relay. If I can find the main relay in my car, using your directions, I think I can fix the problem. Do you have any ideas about how to find the main relay?

                          Thanks for responding. It is a crank no start problem. I am very good using a volt meter.

                                  In your attached schematic of the fuel pump ckt, you show a blue line showing a low voltage path. Where is the low voltage coming from?
