Fuel question

Asked by Aug 16, 2016 at 08:07 AM about the 1988 Ford F-150

Question type: Maintenance & Repair

I have a 88 Ford F-150. I'm at the beach as
soon as I switched tanks I started losing
power then about 2 miles later she cut off
and know will not start!  I have replaced
EVERYTHING I can think of except the fuel
injectors.  its turning over but won't start. I
replace fuel filter ( it was dirty) EGR  valve,
coil, the  sensors the  distributor module
and the  throttle Portion circuit. ( that's
what the code read to replace) still with no
luck. I'm out of ideas. I have 45 pounds of
press going to the rail both tanks are
working and the pump

Spray a little starter fluid in the intake and crank it, if it fires and runs briefly then there is problem with fuel delivery, as you have fuel pressure I would check to see if you have injector power and a trigger signal from the ECM. If it doesn't fire off, then check for a good spark, if no spark unplug the spout connector, and recheck if you get spark the ECM is bad, if still no spark unplug ignition coil and check for ignition power and then test for a coil pulse on the negative connection of the coil wires, if you get a pulse then replace coil, if no pulse, replace ignition module and distributor pickup coil.

Thank you. The problem ended up being the fuel injectors where dirty and needed to be cleaned. They run the tank down to empty before switching tanks and it threw trash in the injectors.


Oh no, how is the fuel regulator? Watch it cause it might be the next thing to go if the crud got to the injectors then a lot of it went through the regulator.

We replaced that too just to be safe.


Fuel pressures are good right now, but if you start to experience power problems later on recheck the fuel pressures, the crud may have damaged the vanes in the pumps and it may take a while before they show up.
