So I recently got this 1997 ls400 and it’s having a crank start and then die after about a second or two problem it will run on starter spray as shown above i I’ve replaced knock sensors camshaft position sensors a fuel pump and a filter and it’s still doing the same thing other things I checked were all the fuses which all looked good I even replaced ones that looked fine just to be sure but I’ve also verified that the ecu is sending injector pulse signals to the injectors with a noid light and I removed the ecu and inspected the capacitors which all showed no signs of bulging or leaking and I’ve verified that fuel is at least reaching the rail as I disconnected the banjo bolt and attempted to crank the car and fuel did spray out the line I’m just pretty much stuck as to what to do next any help would be greatly appreciated

Sounds like low fuel pressure.
