I recently changed over from air springs to coil springs. When I took the car off the jack stands it would not start. I don't know if I inadvertedly disconnected something when I made the change over or what. I checked the cutoff switch in the trunk and it was good. I put in a new fuel relay switch and a new fuel filter. Is there anything else I can diagnois before I come to the conclusion that the fuel pump just went bad while I was working on the suspension. How do you check to see if there is power to the fuel pump? I did spray starter fluid in the engine and it started....
