Customer Question
2010 F150 5.4L....

2010 F150 5.4L. Truck will not crank. relay in dash clicks, Steering wheel doesn't lock, anti-theft comes on solid for few seconds then goes out. Check engine light, inti-skid light and wrench light cycle on and off. Battery charged. Help

Mechanic's Assistant: Does the light stay on, or does it blink?

IT blinks, then when I put key in, it comes on solid for about 2-3 seconds then goes out.

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

I will, I just had exhaust manifolds changed. Drove truck last night with no problems. went to start today and no start. I checked codes and no codes are set.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Truck has 157,000 miles on it

sorry this is happening, lets see what we can figure out.

so when you go to crank it does the dash lose power like the truck is under load or does nothing seem to change?

the first thing i would want to do is jump the starter relay and see if we can activate the starter, that would be the first place i want to start to verify that the starter in fact works. it can be a coincidence or it can be something got damaged or shorted when changing the manifolds.

I will have to try this when I get back home. Is the relay on the starter or on the fender somewhere?
Ford Mechanic: Lou P., ASE Certified Technician replied 3 months ago

relay is in the fuse box in the engine bay, clearly labeled starter relay for once lol

so remove the relay and jump a wire across where terminals 3 and 5 go to from the relay and the starter should crank, if not the starter is the issue or power at the starter.

i will be on later today as well so feel free to reply back later when you are with the truck.

sorry took so long.

Ford Mechanic: Lou P., ASE Certified Technician replied 3 months ago

so since the starter kicked in that means that the circuit is good and something is preventing the truck from starting.

does the dash show Park correctly?

what about neutral?

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
