so your saying that the vehicle cranks a long time before starting and
runs rough when it does.....//there is a port on the fuel rail that you can
put a gauge on and monitor the pressure .....// what you should see is
with the key just turned on and not to the run/crank position the fuel
pump will run for a few seconds to prim the fuel system ....running fuel
pressure should be 52 psi...and maintain pressure after the engine is
shut down and should not drop...it sounds like your pump is not
holding in the rail and when you crank it over to start it takes
sometime to build the pressure and then it has to bleed the air out and
that's why the rough running....see if you can get a gauge and test the
fuel presure
