2000 Chevrolet Express Repair Question
Chevrolet Express Speedometer Problem
I have fuel pressure at rail, so I tried spraying starting fluid into the intake to check possible injector fail, got backfire out of the intake manifold, it sounds like a timing issue, does the speedometer quark relate to a major computer issue or something smaller like a possible short or a positioning sensor fail?
What should I do next?
common issue is the distributor lower gear wears out and the spark for the plugs goes way off. have someone check this for you

How much slap is normal? I have about 10 degrees of rotation and some vertical play. Would the mechanical wear to the lower gear attribute to the speedometer jumping?
