What is your question?
2002 GMC Yukon 5.3 cranks but no start. Code P0336 (crank sensor) Replaced sensor, checked all wires from sensor to ECM all good continuity , turned over by hand got on/off signal, fuel pressure at 55 psi. Checked cam sensor all good. Tested injectors all buzzing, battery good turns over fine, put gas pedal to floor seams to misfire while cranking. What have I missed?
