05 chevy suburban is having problems starting, it takes 20 cranks before it will start.
we have had the battery, starter, and alternator checked all are fine.. Also the
speedometer has been jumping.
Long crank times can be caused by the fuel pressure bleeding off over night because of a bad check valve in the fuel pump in the tank. Also the fuel pressure regulator may do the same thing.
Well we finally figured out that our starter was bad.. the said it just didnt show up that it was going the last time they checked it.All is good it just took a year for it to finally go.
