I have a 94 4.9L straight 6 f150 with 151,879k miles and every time I turn the ignition I just hear one click nothing else. I’ve changed the battery, solenoid, and starter still nothing. My wires have no problems that I can visually see I checked the top to bottom. Nothing is locked up I took the belt off and checked and I can turn the motor manually perfectly fine. Any thoughts or ideas would be very appreciated I’m at a loss with this one.
Might be a problem with the neutral safety switch. The click you hear might a relay somewhere. Try starting it in neutral.
Yeah I’ve tried to start it in neutral and in drive and then both again with a roll start still nothing
Have you verified at least 12v at the battery before trying to start? Have you verified all connections are tight- Batt, solenoid, starter?
with the truck in park or neutral (auto trans? manual?) can you jump the starter solenoid and get the engine to turn over? If this has a fender mounted solenoid, that could be the click you hear. Power getting to that solenoid from the ign switch, but power not going thru it to get to he starter. Check for 12v on the battery side, then check for approx that on the other side with someone turning the ign key.
Yeah the battery checking in at 12.7 V . It’s an automatic trans. I’ve tried jumping the solenoid both times on the old one and new one (fender mounted) and the starter clicks but still nothing. All connections are good I’ve double checked and triple checked.
My truck doesn’t have a starter relay
No wires are touching on the solenoid I’ve checked that already
If my flywheel is locked will it still click like that just the one click?
you wouldn’t be able to turn your motor by hand if the flywheel was “locked”
Man then I’m at a loss I’m so confused
Is the thick cable from the battery + to the starter motor bad - internal corrosion, for example? On a 1994 vehicle that would be a possibility. Try something in its place - a heavy jumper cable, for example - unless you have an actual heavy cable with the correct end fittings on hand.
Can you turn the engine over by hand, with a big lever on the harmonic balancer? - that eliminates one reason for a single click and no turning over.
Yeah I’m able to crank the motor by hand and no pulleys are locked up. I’m not sure about internal corrosion ok the cables I can only tell by what I see that they’re fine, I would use a voltmeter if I had one that would make that pretty easy to check. The only way I was able to check my battery is because I had a friend with me that had one
Check for voltage on the battery cables at the starter- the one wire from the solenoid should go right to the starter. When cranking, it should be 10-12v on both ends of that wire. -if ivoltage is about 12v at the solenoid- the solenoid is working (both big plugs at the solenoid should be about 12v, and should be the same.)
-If voltage is about 12v at the starter when cranking, then the wire is good- your starter is bad.
-If voltage is not about 12v at the starter, but voltage is 12v at the solenoid- and you are sure you are working the same wire- then you have a broken or defective wire.
He would like to, but
ok? Then OP knows what to check when they can borrow a voltmeter again.
OP asked for input, I gave input.
lol yeah that’s what I need to do that’s why ya told me. I was gonna pick one up at autozone but they don’t have any of the cheap ones so I’m just gonna assume based on everything it isn’t that it is the wires. That litterally the only thing left that it could be and if it’s not then hey that’s one more thing I don’t gotta replace later
And if new cables don’t work I’m just gonna rip everything out and put me a 302 in there
Is there a Goodwill store nearby? They might have a VOM that was donated. Worth a look. Also, one of the public libraries in my county has tools you can check out. Really! Check on line or call the library and ask. If that branch doesn’t, a nearby branch might. Ask about it.
