Why does it show all cylinders misfiring

Question

No p0300 but p0301-p0306 codes. Thinking crank sensor. Will start and run for 5 seconds

Answer 1

Hi there

Usually when you have misfires on all cylinders it's either the result of low fuel pressure, an intake manifold vacuum leak or a problem with the timing belt. If you don't have a code for the crank sensor then the sensor is likely fine.
