Unhappy HELP 92 aerostar engine problem ?

92 aerostar 3.0L auto

Previously my aerostar was starting o.k running rough and black exhaust fouling the
Oxygen sensor exhaust pipe. So I cleaned the MAF sensor. Replaced the Throttle position sensor, air bypass sensor, oxygen sensor and replace the fuel pressure reg. cleaned ever connector I could find and the engine still wonít run.

Now it wonít start and when I turn the ignition on, the fuel pump is making a loud
Whining noise. ? The pump never made noise before but canít see how the engine is
Fouling if there is a problem with the fuel pump.

No codes

do you think you may be burning a significant amount of oil?

HELP 92 aerostar engine problem ?

Thank you for the comment, but I'am sure its burning very rich. When I turn the ignition on and the relays click in and out and the fuel pump stops
whining the van starts. It just started runs rough even idles but the engine
is running rough and you can see black smoke coming out of the tail pipe.
relay problem bad connection ?

Maybe its misfiring ?
