truck starts itself ***
i have a 97 f150 that as soon as i hook up the battery the truck tries to start itself what would cause this

Faulty starter wiring would be the first place to look. R&R if need-be or just do a thorough check of all wiring. If nothing is apparent, move to the ignition.
Does the truck start and run? If so, does the starter continue to cycle as you're driving? |
Bad starter relay possibly. To troubleshoot, there is a tan/red wire that supplies the start signal from the key switch/DTR switch. When the key is turned to start, this wire is hot. Any other time it would not be hot. Pull this wire off of the starter relay with the battery hooked up. If the starter stops with this wire disconnected, then the relay is good and there is some problem with the tan/red wire. If the starter still runs with this wire disconnected, the relay is bad. Good luck! :-wink

This will happen if the 2 wires have been switched on the solenoid, Did you by chance accidently switch the wires around while working under the hood?

2001 ford starts its self
i have a 2001 ford and it want to try and start its self when i turn the lights on but then the radio goes out and the heater comes on. I tried to replace the solenoid on the fire wall and now i cant get the stater to stop unless i take the wire that runs to the alternator off? and so i got under the truck to check the starter and there is a solenoid on the starter too? Can anyone help?

I second that |
The ignition switch closes power to the start relay.
This relay has heavy contacts to pass current to the starter motor. They often burn closed from use. ************************************************** ***** I have a problem with the poster who left his truck in the garage and it started by it'self and ran through. First, if an automatic trans and left in Park it cannot just run away. Left in neutral, the trans still will not move the truck. Left in any other gear, the starter will not engage. If a manuel trans and left in gear, yes the truck will move. For a fault start, the key would have to be in the ignition with a PATS system in play and a the igntion left in the Run position. To many safetys to defeat for a self start and run, to happen like that. Question is, in what condition was the truck left in for any possability of self starting 'and moving' even if there was a fault present? I have never heard of this before, happening as the poster discribed. |

Since I have been in the garage door business for 30 years, I have actually heard this from customers many times....:-roll |
Better ask them some questons and find out the real truth.
. Hell ,the power windows are even sensitive to getting a childs head or hand caught in a closing window. They auto stop before any real injury is done. Few know this feature is designed in. This is a lot like the cars that accelerated by themselves out of control a couple years ago. It was all a farce in the end. |
