Customer Question

Friend has older f250. New battery cyleloid & starter. Truck still won't start ?m

Hello. I suppose it's safe to assume since you have tried a starter and a battery that the issue is no crank..

If you touch the large lugs together on the starter relay mounted on the fender, will it crank?

Expert:  AZTechBrian replied 1 year ago.

by touch them together, I mean with a screw driver, or pair of channel locks, etc. If it does crank, replace the relay. Please let me know once you have tried it whether it worked or not.

Customer: replied 1 year ago.
Ok it will be awhile thank you
Expert:  AZTechBrian replied 1 year ago.

No problem. Take your time.

Customer: replied 1 year ago.
Truck is 92 f250 where is the starter relay located
Expert:  AZTechBrian replied 1 year ago.

It should be on the passenger side fender. which engine does it have?

Customer: replied 1 year ago.
Is the picture you sent of the relay? I'm sorry I'm trying to talk to you and text the info.
Expert:  AZTechBrian replied 1 year ago.

yes.. that is a picture of the relay.

Customer: replied 1 year ago.
Ok
Customer: replied 1 year ago.
He changed that & new cables
Expert:  AZTechBrian replied 1 year ago.

OK. If he touches the two large terminals together does the starter crank?

Customer: replied 1 year ago.
Engine 460
Customer: replied 1 year ago.
No just clicks
Expert:  AZTechBrian replied 1 year ago.

And he replaced the starter and the starter solenoid as well as the relay?

Customer: replied 1 year ago.
Expert:  AZTechBrian replied 1 year ago.

He also replaced all the battery cables?

Customer: replied 1 year ago.
Please send pic of seleniod
Customer: replied 1 year ago.
He says pic is of solenoid
Expert:  AZTechBrian replied 1 year ago.

It usually comes with the starter motor. If he replaced the starter motor, I would imagine it was replaced right along with it. Here is a picture.

Customer: replied 1 year ago.
Ok then what's next?
Expert:  AZTechBrian replied 1 year ago.

If that's fine, check to make sure all cables are in good shape and making good contact. they should be since he said he replaced them all. If that's fine, Try jump starting the truck just to make sure that it isn't a lack of battery power problem. Just having the volts doesn't mean we have the amps to crank the engine. If that checks out good, try turning the engine by hand at the crank bolt with a large ratchet or breaker bar and a socket to make sure that the engine isn't locked up.

Customer: replied 1 year ago.
It isn't locked up. Can be jumped. Battery brand new
Expert:  AZTechBrian replied 1 year ago.

If you jump it, the engine will crank?

Customer: replied 1 year ago.
Yep
Expert:  AZTechBrian replied 1 year ago.

Ok. Lets try something.. remove the negative cable on the battery of the truck, and connect the jumper cables to the battery of the jumper vehicle and to the cables of the truck leaving the negative cable disconnected on the truck so you are only trying to crank it with the other battery and not using the battery in the truck for assistance. will it crank then?

Expert:  AZTechBrian replied 1 year ago.

That's basically trying another battery

Expert:  AZTechBrian replied 1 year ago.

next question is, when it cranks with the jumpers attached, does it crank normal, or very slow?

Customer: replied 1 year ago.
He said no it won't jump. Sorry I was not understanding what he said. Has to go back to the truck. May be awhile b4 I can answer back
Expert:  AZTechBrian replied 1 year ago.

that's fine. So, it sounds like the truck will only crank if it has the power of 2 batteries assisting it. ask him when it cranks if it sounds like it's cranking normal, or if it seems slow. If it seems slow, ask him to remove the accessory belts and then try cranking it.

Customer: replied 1 year ago.
Ok. This may take a good while. I hope I can come back to this chat later
Expert:  AZTechBrian replied 1 year ago.

absolutely. You can come back to this chat at any time. If I don't answer right away, it means I am busy but i will answer as soon as i am able to.

Customer: replied 1 year ago.
Says when it would crank it didn't crank slow. Just quit running replaced all that stuff just clicks. Still try removing accessory belts??
Customer: replied 1 year ago.
If it cranks without belts what does that mean ??
Expert:  AZTechBrian replied 1 year ago.

Removing the belts is a quick and easy test. If it cranks with the belts removed then it would indicate that one of the accessories is locked up and not allowing the engine to crank. I can't think of many reasons why one battery isn't enough to crank the engine, but two batteries is. I am thinking either a bad connection somewhere, or excessive resistance requiring more power.

Customer: replied 1 year ago.
Ok perfect thank you
Expert:  AZTechBrian replied 1 year ago.

Your welcome. Let me know what he finds when he removes the belts.

Customer: replied 1 year ago.
I will. Thank you
Customer: replied 1 year ago.
He says it serpenten belt. Does that matter
Expert:  AZTechBrian replied 1 year ago.

That's the belt. I believe that engine has 2 of them. . Its been a while since I worked on an old 460..
