Wife went to Bakersfield yesterday for a doctors visit. Ran fine. When
she got out..wouldnt fire up. No fuel at the Schrader valve.
Had it towed home
The problem..is there is a full 15 gallons of gas in the tank and the
truck pump will not pump any fuel.
When you turn on the key..there is no pump sound coming from the gas
So with this in mind..I searched the web and the 2 Haynes books I have
for data to diagnose the problem.
There is so much bullshit data on the Ranger..its impossible to find
any good information
The Haynes books are not much better when it comes to fuel system.
2001 Ranger XLT, 3.0 "Not Flex Fuel"
1. There is a 20 amp fuse (good) in the power distribution box under
Next step is to test the fuel pump relay..and here lies the problem #1
Which one is it????
A web search turns up "K4" (no such markings in my distribution box)
"Lower right hand relay" (empty socket)
etc etc etc.
Haynes doesnt show it either.
The next item is the Emergency Fuel Pump Shutoff switch, located on
the passengers side, up against the firewall. Found it (not in the
marked location in any manual/guide) and its not tripped. So I pulled
the connector and measured voltage (7.5vts..which is a bit odd) and
then jumpered the connector with a paperclip. Still no pump run. I
left the jumper in place. One would think that that shock switch
should be passing battery voltage..12.35 volts ...in and then out
There is several multiple wire disconnects between the fuse box and
the fuel pump which is hidden from view on top of the ful fuel tank.
No manual/guide tells me what wire/wires or wire colors Im searching
for between the fuel tank and the fuse box..or what color, or where
the fuck they run. If I could know that the "Green/Yellow" were power
to the pump...it would be a no brainer to test, close to the tank.
So unless one of you gentlemen have any idea of how to id and test the
fuel pump relay (one of a shitload, all the same (2) types...or any
other places to look..Im going to have to drain the gas tank and drop
it. Which Im hoping not to have to do.
Ive never seen a fuel pump simply quit on arrival..and never pump
again....so my gut feeling..is its electrical. They tend to get
weaker and weaker..but never had one simply quit.
Also..anyone know of a place that sells fuel pumps for less than the
$235!!!!!! that Autozone wants for theirs? CarQuest is about the same
price. Any alternative suggestions?
