Engine Performance (A8)Pregunta 110 de 120
A no-start with no spark and no injector pulse, but a good battery and cranking, most likely points to:
a.A worn water pump
b.A clogged cabin filter
c.A failed crankshaft position sensor or PCM/power issue
d.A leaking A/C condenser
Explicación
When both spark and injector pulse are absent during cranking, a shared input such as the crankshaft position sensor or a PCM power/ground problem is a prime suspect. Scan-tool rpm during cranking helps confirm the crank signal. Systematic checks of power, ground, and reference sensors isolate the cause.
