Spark good, fule 55psi and have injector pulse. No codes. T.P.S ok, rpm ok, coolant temp ok. After turning key off and back to start about 15-25 times truck will start and then start all day long no VTD codes I have replaced cap, rotor, wiers and pluges. This is a 4.3 v6 vin code W. When I pour fuel ioto throttle body engine will start how can I check fuel injectors

With the spider fuel system pressure is 60--66psi, key on engine off. Also, the fuel poppets may need cleaning.

If fuel pressure drops like a rock with key off, you have a pressure leak.
