Please help me guys,i got a 2wd saph that just refuses to start. The plugs are not getting the fuel for some reason. I took injectors out and replaced them but before puttin them back in,i cranked the engine to see if they are spraying and they arent. They all pulse when you turn the ignition onbut when cranking over its all over the show with usually just one pulsing. ive changed the crank and phase sensor and tried a different ecu. Any ideas??? Many thanks...
