No starter operation the engine does not crank over?

SCGRANTURISMO you nailed it. Thank you so much. I relocated the ground ans everything is functioning properly. I really appreciate it.

I removed the fuel injectors reassemble, the truck won't
crank just a rattle behind the engine. Sounds like when the starter is bad.

The problem started when I left in the morning, my windows, radio, and dome light stopped working. I got home and attempted to fix the problem. I was not getting any voltage to the ignition wire going from my radio so I jumped a different wire and all electronics working again. I attempted to start the car and nothing happened which I thought was very peculiar. So far I have obviously checked the battery, starter, and ignition switch. The only thing I have discovered is that the starter relay in the hood is not getting power when the key is turned to ignition. Any further suggestions would be greatly appreciated. One more thing, jumping the starter does crank it and clipping the relay also cranks it.

Currently look at slot 21 and there is no 15 amp in the slot.

I appreciate quick help. I wasn’t aware that the fuse fell out. I replaced the fuse with a 15 amp and started up right away.

Truck won't start consistently but trip/odometer gauge stays lit with dashes not numbers, under dash I can hear a rapid ticking/crackling sound. Fuel pump is new after same problem over a month ago. Battery is new. After-market auto car starter was installed before I purchased, could this be part of the problem?

Local Ford dealer did diagnostic check and found that the alternator was bad but my mechanic tested and it was fine.

My mechanic found shorted wires in the drivers door, and engine side of firewall, and along the frame rail under truck bed.

One shorted wire went to the fuel pump and the other went to the power mirrors. There were only two, I was mistaken on the third.

I unplugged the battery 7 days ago and left it overnight. The next morning I was able to start it and it has been running for a week. This morning I went out to start it and the door chime went off with out the key in the ignition. The truck started but when I put it in gear the 4x4 dash light was clicking rapidly, in Neutral it went out but came back on in Drive. When the light was on the power windows would not work, but when it went out the window would. I could smell something like hot wires under the dash when I got home from a 6 mile drive.

The last time the truck wouldn't start it had been raining all night, and this time was the same. Could moisture be getting in somewhere?

I checked under the dash on the driver's side and the carpet WAS very wet. Has the windshield checked out at Portland Glass and they found that three quarters of the factory installed windshield was not properly sealed.

Thank you for your help so far, I had the truck washed today and have had no problems yet. More water was used on the windshield and seal to see if there was still a leak and there was none.

I attempted to replace the battery cables on my truck. I disconnected the cables from the starter relay module on the firewall. When I realized how difficult replacing the cables was going to be I decided to just replace the battery connector clamps instead. I hooked everything back up. When I hooked up the starter relay module I put the wires on wrong (I didn't know this until after I replaced the battery and the starter later). I connected the cable from the battery correctly but, the 2 wires from the starter and the alternator were incorrect. They were both supposed to connect to the same post on the starter relay module but, I put one on the lower post and the other on the top post. Anyhow, I started the engine and it fired up immediately. I heard a loud crackling sound from under the hood and I jumped out to see what it was. I couldn't see anything and I couldn't make out where the sound was coming from because of the fan motor making so much noise. As I was looking for the sound it just suddenly stopped and the engine sounded normal again. I shut off the engine and tried to restart but, all it does is make a single click at the starter relay module. After I realized much later that the wires were placed incorrectly, I replace the starter relay module as well, but it still just makes a single click when I turn the key. I have checked all the fuses that I know of under the hood and under the dash. I don't know how to test relays in the fuse box. I don't know what else to check. Please help.

I have a 2002 F150 5.4L engine. When I try to start my truck it does nothing no noise no turn over. Battery is fine all lights work. Had the starter checked it is fine. Had my after market auto starter and theft device checked all installed and works fine. The truck will not start however. What else could it be. Looked for a starter relay however there isnt one. Is there one in the computer mechenism? Any suggestions that could point me in the right direction would help. Truck just stopped starting. Then started maybe 5 times after doing nothing to it and now wont start again.
