gotchagarage Posted July 9, 2005 Share Posted July 9, 2005 This morning I wanted to start my LS-400 / 1991 only 105k miles, but it's only cranking. It is sparking by the sparkplugs, probably a gasoline related problem. I did check the fuses, but they are all good, I also switchd the selenoids EFI and Horn, but also without any result. How can I check if the fuel pomp is working. Can I put 12V directly on the fuel pomp ( by the tank). With connector is for the fuel pomp and what wire is the positive ?
