Fuel pump problem??
Here's my problem and diagnosis. I need a reassurance from ya'll to see if I am on the right path.
About 2 weeks ago, I was coming back from a 60 mile trip and noticed my truck was starting to hesitate. I was going steady at 75 mph. So I thought maybe the filter and water seperator was the suspect. Then I remembered I got fuel out of a tank from a buddy of mine, well, the tank was almost empty and I know I got some sediment from it. The proof was in my filter bowl on the top of the motor.So I cleaned it out, replaced the filter and whatnot and drove the next day.
So, on my way home, I get on the interstate and she's chugging real bad. Steering wheel is shakin, barely staying at 50 mph and starting to leave a small cloud of white smoke.Feels like it's dying for fuel. I let off the pedal and it stops, get back on it and it keeps on happening. I make it home.
Today, I start looking. I think its my fuel sending unit under the driver's side door, but it was making a whining noise for about 5 seconds after the glow plugs heat up. Just to use for a gauge of time to how long it will whine when I turn the key.
So I take it out, monkey around with it for a minute and see nothing incriminating. For the peace of mind, I want to know if the pump in the tank has went bad. I put the fuel line in a clear glass bottle, turn the key and no fuel comes out. I double check everything and try again to have the same results.
My question is, will the fuel pump work without the sending unit being hooked up? Are they linked together electronically somehow? And is the little aluminum looking cylider coverd in black rubber foam, under the drivers side door, the sending unit?
I did not check for electric to be at the pump in tank, but I am confident nothing has been goofed around with.
Sorry for the long discription but I am trying to give the best description I can. What do you guys think?
