Question about 1990 Ford F150

2 Answers

2004 F150 heritage, 4.2L V6 wont crank, has power

I replaced the two relays under the dash, because they were clicking. Now I have dash lights again, but the truck still wont start. I really dont know how to tell if the relays are bad without them clicking, so I looked at the ones under the hood and I cant tell if they're bad. Any suggestions.

I'd just bypass solenoid to see if starter kicks in. Positive from battery to big lead going to starter. You may want to check lead at starter to see if there's any buildup of corrosion.

Check for power at the starter and starter solenoid while someone holds the key to crank if it has enough voltage the starter is bad but make sure all connections for the battery and starter are good before replacing starter

Truck wont start


It could be the fender mounted starter relay under the hood. Or if you took off the small wire at that relay (its from the ignition switch), it should have voltage when the key is held in start. If it does have power in start, probably the relay. If no power in start, either the switch or the neutral safety switch is acting up.

I'm guessing that it isn't even turning over. There are a couple of things you can check. Both are in the power distribution box under the hood of the vehicle (see picture below). Also below is a picture of the fuse and relay layout. There is one fuse directly related to the starter relay (number 8 marked with a red arrow) and also the starter relay itself (also marked with a red arrow). I hope this helps.
