In June my 1988 Ford F-350 with a 460 started acting up...On damp mornings it had no or weak spark but later in the day it would start and run fine..I put a new coil on it and its never ran since then as then the main fuel pump wouldnt come on..It will run on ether so it has spark..
There was nothing wrong with the old fuel pump but I put a new one on it...Its also had a new fuel pump relay and a new ECU relay but so far nothing has worked..The fuel pump safety switch has been checked...
I know thats theres several more things that it could be but I'm thinking its the computer....I'm not real good on electrical stuff...What do you think it is?? I'm sure that some of you have had similar problems....The old girl still has lots of miles left in it so I need to get it fixed without taking it to someone that will charge plenty to fix it..The 1988-90 Ford F-350's sure have tons of wiring and aren't easy to diagnose..
