stupid question 1992 f-150

Only proper way to check your fuel pump is with a pressure gauge.  That 92' Ford is Fuel Injected correct?  If you suspect the pump, you need to check the pressure at the rail.  I will go out on a whim here ans say that it's not the pump, as all it does is supply fuel, not control air/fuel mixture.  Fill her up and see what happens on the next tank.

    

   My fuel injected 2.9 V6 Ford Bronco II has a Schrader Valve on the fuel injector rail to hook up a gage.  Yours probably does too.  I'll bet it's the front tank fuel pump.  I'm told that replacing the fuel pump is easier if you unbolt the truck bed and raise it up than to drain the tank and unstrap it and try to strap it back.

Any word?

tank out of gas.  normal driving gets me about 17 mpg.  I must have had some really rich gas while the electrical was an issue because it dropped me under 10mpg.  Right now, on my test gas, I got 14.7mpg.  Going to de gunk it and see if that gets me back to 17.  If not, I'll look at the air/fuel mix

These cold temps can really mess with mileage more than some think. 2 MPG wouldn't surprise me at all. Check it when things warm back up some.

What's the easiest, cheapest way to figure out and fix what's wrong.  I figure I first need to see if there's gas in the front tank.  How do I do that?

Stick a hose down the filler and suck, if you get a mouth full of fuel then there is gas in that tank...

Ever consider just fixing the gas gauge?  Shouldn't be to difficult to do.

    When it gets this cold, your engine never really warms up.  Since the mid-60's the engine makers went to thin-wall castings...
