I have an 86 El Cameno with 4.3 V6. Purchased some gas that clogged the fuel
filter. I have changed the fuel filter. I can't get engine to rev up or
idle, it only runs if pumping accel pedal, but boggs when throttle is
opened over quarter throttle. Fuel pump only seems to run for a short time
(3sec.) after cranking. Doesn't continue to run with key in on position
after cranking. Rechecked filter to see if it had clogged again but it is
fine. I used pump as stated above to run about a gallon of fuel into clean
drain pan to inspect for dirt, fuel is now clean. Any sugestions??
Found the problem. Checked fuel pressure at filter, only had about 3# of
pressure. Thought pump had gone bad. Removed fuel tank. Found hose about
one and a half inches long between pump output and tank drop tube had a
small hole that let fuel spray back into tank. Will reinstall tank
