I'm stumped as to what my problem could be. I replaced fuel pump and all the filters, and before lowering the car I ran the pump for about 30 seconds to fill the lines and check for leaks. All was well so I fired it up and it ran fine. Finish putting the rear back together and get tires on, drop it down, and now it doesn't start. I have spark and I have fuel going to the injectors, but they've lost power somehow. I never touched anything between starting it the first time and attempting to the second. Any ideas?
