Hello to all I have a 2003 F-150 When turning the key to try and crank truck no power to the exciter wire on the starter solinoid on fire wall can jump small wire to main power truck will start, Replaced Ignition swith, Both relays in panel under hood all fuse's are good any Ideas this is the secound truck I have seen this happen to!! Any Ideas TKS

 

Check the neutral safety switch, most likely cause since you have already checked all the common things. Put the shift lever in neutral position and while turning the key to start it move the lever back and fourth to see if the starter turns over. Just a thought!

 

Sorry I have put it in netural and Installed new Netural safety switch, Because of two trucks doing the same thing same year I thought maybe a broken wire but on two same trucks!! Thanks though I should have mentioned this Help LOL

 

my 2003 was doing the same thing I don't know for sure what I did that fixed the problem, but I did clean the battery terminals also the starter solenoid terminals and beat the ***** out of the starter, never had an issue since.

I think cause my truck was sitting for a while not being used it developed this problem. After a month of using it for work, the starting issue went away.

I know this doesn't give you an exact answer but just giving you what worked for me.

Have you removed and inspected the condition of the cables going to the starter? Are the Mega fuses on the firewall passenger side ok?

 

New Battery Can jump it from the starter solenoid on fire wall and it cranks and run fine, All fuses are good both starter relays have also been replaced, I'm leading toward a wire ( Node OBD codes) Any one know where I can purchace a Wiring scamatic book Also I have been a mechanic for 35 Years Ford Mechanic and Heavy Cranes ( THANKS FOR TRYING TO HELP GUYS) Keep it coming TKS Mitch

 

Fuse #21 on inside fuse panel looked good but after removing it tested for oms would not read ( Note this fuse onld get's voltage when ignition switch is turned to start position) Then sends power to netural safty switch then to the relay and starter siloniod on fire wall ( Fuse was blown after solinoid went bad) Tks

 

Hi, I have a problem related to this. My starter wire corroded and broke about halfway up. I tried to run a new wire and broke the stud holding it onto the solonoid. I removed the solonoid and replaced with a new one. Now I cant remember where the wires go. I placed the starter wire on the top stud, the double wire on the bottom and two smaller wires on the smaller stud to the side. Now when I crank it it over it just clicks very rapidly, I am not sure if I wired wrong or I installed the solonoid wrong, any help would be appreciated. Also I thought I removed a wire mounted to the starter bolt and frame but I cant find any other wires underneath.....
