1986 F150 Won't Start! - Ford F150 Forum

Alright, here's the problem.. When I try to start my truck all I get is a click! I have no idea what the problem is because I've replaced the battery, battery terminal clamps, positive batter cable, relay, and the starter! I'm not sure where the click is coming from, but it's not the relay. Possibly a grounding issue? I'm stumped.. Please help!!

sounds like a ground problem, undo the ground cable where it bolts to the engine or frame & make sure it is clean, then bolt it back & see if it wii turn over.

I dunno man.. I tried that with the negative ground to the engine and it didn't work. Is there another ground to the frame??

is it a new battery? Eventhough a battery shows it is charged, it really needs to have a load test to be sure it is capable to start an engine. I had a similar problem a few months back, drove me crazy, it was the ground cable on the battery, replaced it all was good.

check the terminals both on the power and hte ground side, sometimes corrosion gets in, and causes the same problem,

Take a battery jumper cable from the starter itself (not the terminal but the body)to a clean spot on the frame. If it works, the starter has a bad ground. I assume when you say relay you mean the solenoid. If you haven't replaced the solenoid, that's probably the issue. Also check the ground strap on the engine. A lot of times these things get corroded and the engine will run/start much better once cleaned.

Yeah, I replaced to solenoid but that wasn't it. Turns out the starter was bad too so I got a new but it didn't really help.. Every time I try to start her up she just grinds now. I looked at the flywheel and it looked pretty good! I'm thinking maybe the engine is seized.. If this is the problem how do I go about unseizing it??

Put a socket with a long handle on the crankshaft pulley and see if you can turn it by hand. If you can, the gear teeth ring on the flywheel/flexplate may have come loose and needs rewelding. Yours wouldn't be the first I've seen come apart.
