Re: Off Topic....Need advice for ford pickup



I'm no expert, but the fuel pressure could be low,
making the computer decide to go to full open on the
fuel injectors in order to get enough fuel into the
engine.    The dealer may not have wanted to check the
fuel pressure because it is sometimes hard to find a
place to tap into the fuel supply line.  On my son's
Chevy pickup I had to get under the truck and replace
the fuel filter with a "T" connected to a gauge. 
There was no where else to check the pressure.

If the fuel pressure is low, it could be a bad fuel
pressure regulator or a bad fuel pump or a plugged
fuel filter.

There's a related problem referenced about halfway
down the page on this reference:
