'03 2.5L Ford Ranger Standard Trans, Engine at times won't turn over, does not click, battery is fully charged.

Ensure you have "ALL" the wires connected and a fully charged battery. Then use your remote to turn off the anti theft devises and your truck should start with no problems. You may have to switch the anti theft device from your old engine to your new one or take the vin of the new engine to the dealer and get the code for that engine.

your starter is bad.

Find the starter solenoid. Follow the positive battery cable to the black round solenoid. There should be a small wire attached to it that is red with a think a green tracer. Remove that wire and then try to start. If it starts replace the ignition module.

The solenoid mounted on the starter is shorted out. It can be replaced separetely or it will come on a rebuilt starter as well

Hey there sluggo,

I'll assume the battery is fully charged and get right to the solenoid.

The solenoid is a really HEAVY DUTY switch. A lot of Amps need to pass through it for you starter to turn your engine.

Inside it are two copper contacts that look like the head of a bolt only rounded. The battery is attached to one, the starter to the other. Hovering above them on a spring is a copper clad disk.

When you turn your key (in a perfect world), an electromagnet is activated that yanks the disk towards the contacts. When they connect, the circuit is closed and the starter turns over. OK.

Well, as you can imagine, each time the disk makes contact, there is a bit of sparkage which can erode the copper plate on the disc. The reason it IS a disc is that it rotates a bit each time it connects. This way the contact surface lasts much longer.

After a while though, you do start to hit bad areas. Thats when it's time to replace it.

Again, that is all dependent on the battery being fully charged.

I wanted to explain what was happening rather than just saying 'replace it'

Best regards to you

You should have your battery tested & make sure that the terminals are cleaned & well protected wth grease once charged fully. Since you crossed/jumped the solenoid & didn't get it to start until jumping the battery (providing extra voltage), that rules out the solenoid and the ignition switch. Sometimes a battery will test full without a load but will not provide the voltage to the solenoid to actually complete the circuit, thus the clicking sound. If the battery is strong, and the starter bad, the solenoid will click solidly once, passing full voltage to the starter that will either turn,hum, or do nothing. good luck

Starter could be stuck..
If you are SURE you battery is fully charged with no dead cells..
Try --
(takes 2 peopl) -
Turn the key like you are trying to start it.
At the SAME time - smack the starter with a small hammer not too too hard..
Let me know what happens..

you need to try a new battery sounds like your battery has gone bad

Check your battery

check the connections on your startermotor are all ok... mainly earthing... try using your jumpers to ground the engine to your battery... and hey try push starting... dont need a starter motor that way and lets you know if the engine is ok
