need some help guys....no start condition no my sons 97 f150 4.6 165,000.Souith Dakota truck so all connections look real good...good battery,newer neutral safety switch(10,000 miles).When you attempt to start you get just 1 click...tried jumping across firewall solenoid no help...but not 12 volts to the s/command? wire to the firewall solenoid....I think in a tried start situation I should have 12 volts...so where to look????

 

Battery? How old is it and have you tried to put a booster (jump) to it? Sounds like its old and wont hold a charge.

 

battery good and charged.....no 12 volts at the firewall solenoid...should point towards ignition....but dont know the test path....

 

The "clicking" sound is definitely before the starter. If it was ignition there would be cranking at least.

 

where does the 12 volt firewall solenoid wire go to?

 

a friend mentioned putting 12 volts to the firewall solenoid and then jumping across the solenoid to see if its starts.....does this sound reasonable?? don't want to fry something......are there any fuseable links between the ignition and the firewall solenoid?

 

no ideas out there guys????

 

the orange wire with red line going to the firewall solenoid only has 4 volts on it when the key is on....should be 12volts?? anyone familiar with this circuit??
Ok,got it started was a broken 12 volt wire to the starter.....but I still have only 4 volts to the firewall solenoid....key on 4 volts...key off 4 volts...can someone out there check their truck to see what the voltages are at the firewall solenoid(right next to the battery..will have to pull off plastic panel..) Thanks

 

Hey no answers out there???? someone has to have come across this issue.I checked a friends f150 he had 0 volts then 12 volts when key is turned on..... anyone?????
