I checked the power to the relay,12+v, checked the fuse, replaced the relay. Still wouldn't start. I tapped the fuel pump with a wrench and checked some wiring up under the hood.. Went and turned the key and the pump energized. Shut the car off. Wouldn't restart. Fuel pump did not energize. Let the cat cool off. Tapped the pump again. Went back about 5 minutes later the pump energized. My question is The wiring on the relay comes from where. There is a hot and a ground and three other wires. What components are involved in getting the pump to charge? The ignition? (It's not very old and lightly used) What else? How hard is it to change a fuel pump on 91 Vert. Everything can be seen by removing the back license plate. The dealership said something about a communication error. Possible ECM, CCM issue. I think it's the fuel pump. Thoughts? I pulled it out of the dealership at no charge to us for their failed diagnosis. Thanks in advance.
