wont start - clicking in passenger side dash

[boilerman]

when i try to start my 85 4x4 king cab 720, i hear a clicking in the dash on the passenger side. i have checked the battery and replaced the starter...any help will be appriciated.

before you all ask...everything else works...radio...heater fan...lights...just no juice to the starter...

So it won't turn over? I know the fuel pump relay is down in the passenger side of the dash.

My vote is that you have either a bad ground connection to the battery, or possibly BOTH of your battery connections have a bad connection, or you have a nearly dead battery. The clicks you hear are various relays. One is the fuel pump relay over on the PS just beneath the glove box. The click is normal. It sounds like the battery has enough juice getting though to power lights and radio and relays but not enough to crank the starter.

Try another battery. Have your current battery tested at the auto parts store. If that doesn't solve the problem then you have a bad connection at one of the fusable links. Test the battery first.

I had mine make that same clicking noise on two separate occasions. Both times it ended up being a dead alternator. Did your battery charge light on the dash ever come on to warn you that something was wrong?

Assuming the truck is not even cranking, here are the Diagnostics:
Have someone jump it.. if it starts, the battery was dead
Drive it to a parts shop and have the battery and alt tested... bound to be one of the two.

If it is cranking, you're not getting fuel and it most likely is the fuel relay down over there under the dash.
