Got a stumper, When turn key on, hear clicking under dash in center adn truck wont start. Found 2 relays and flasher there, replaced relays, still have problem. Truck will start when relays dont click. Realy bad when cold.

 

Batteries are taking a dump on you- have them tested. If one is bad, replace BOTH. If you only replace one, the old one will drag the new one down. Welcome to FTE!

 

Chase nailed it. I had the same issue. TWO new batteries and all is well.

Welcome to FTE.

 

Sounds like a battery issue to me too, especially when you mentioned that colder weather makes it worse. If you have one bad battery, then you only have a marginal amount of juice to crank the truck in ideal weather. In the winter time and in colder temps, all bets are off.

 

Welcome to FTE.

I had the same thing happen to me. I was wondering what the heck is all that crap ticking. 2 batteries later, good to go.

 

Yes, I killed mine on a minus 5 degree day a couple of winter's ago.

 

i was just about to ask the exact question, i have a ford courier work ute and only drive my truck on the weekends now, the other day i stopped at the shops and turned the car off and it sounded like my indicators were on and flashing like crazy so i turned the key back on and it stopped but i had no power at all after turning the key off and on a couple of times it all came good. does this sound like the batterys are on there way out also.
i did check the batterys with a multimeter and one was a couple of volts lower than the other...

 

I would clean the post on the batteries, and it also sounds like a grround problem.

 

Besides, you should check the voltage under a load. If it drops below 10.5 ( i believe) is when you get the clicking..

 

it just seemed weird cause it has never given me a problem before ever, i'll give the batteries a clean and see how it goes.
when you say check under load, do you mean having the engine running with maybe the headlights and the A/C going.

 

Have someone start your truck while you check the voltage at the batteries.

 

cool thanks dave i'll give it a go
