Q: Takes a long time to crank .

asked by on

Let a shade tree mechanic change the distributor and he didn't put it back on right took to Firestone and they put it back on right but it still takes a long time to crank? Changed the oil sensor unit, crank sensor ,camshaft sensor and still does the same thing.. Any idea on what the problem could be???

My car has 2070000 miles.
My car has an automatic transmission.

I would ensure you are getting strong spark with a spark tester (available for a few dollars). Depending on the version of the 4.3L you have, they are known for having problems with the fuel system.

For example, if you have a plastic intake manifold on the center of the engine, they are know for leaking fuel pressure regulators. Regardless, you need to check for fuel pressure with a fuel pressure gauge (also not very expensive). The connection port is on the rear driver side of the engine with a cap on a steel line. The pressure with key on, engine off should be at least 45-50 PSI and should not drop. If the pressure is not there or leaks down I would suspect a bad fuel pump or a bad fuel injection unit (if you have the plastic intake).

If the vehicle runs fine when started, I would suspect the fuel pump based upon experience. Also, have your battery tested.

If you need some help with this, consider YourMechanic, as a certified mechanic can come diagnose your starting issue and make the necessary repairs.
