<pre wrap="">I have a 1988 ford thunderbird 5.0 engine. I can"t get any
the tank to the engine. I have replaced the fuel relay and fuel pump
with no results. Will a bad computer cause this problem? Can anyone
suggest other areas to look into with this problem. THANKS.
Start at the pump and check for current. If no current there, work your way
back. It could easily be a bad wire or connection.
Does the pump make noise when you turn the key on?
How about if you ground the tan/light-green wire at the EEC test plug
under the hood while the key is on?
Have you checked/reset the "impact" switch in the trunk (behind the hole in the
trunk liner by the left taillight)?
How about bypassing the impact switch with a piece of wire?
Is there power at the big yellow wire at the fuel pump relay?
Try jumping the yellow and the pink-black at the relay. That will give direct
power from battery to pump, assuming the blue fusible link isn't blown.
Fuel pump does not make any noise when I turn the switch to the on
position. I checked the voltage coming into the relay and got about 8
volts. Is that about right? Coming out the relay before I get to the
tank , I get about 3 volts. I have not checked any of the other
suggestion from you, but will. Thanks!
I just want thank for your advise on the thing that I need to check. It
was a bad impact switch. I jumped the impact switch to the fuel pump
and everything worked fine.
Thank you very much for your advise!!!
Glad you found the problem. Those switches sometimes go bad, and
can sometimes just get "triggered" by a hard knock, like slamming the
trunk too hard when parked on a hill, and need to be reset by pushing the
button on top.
