Ay guys,

My dad just recently bought a 04 ranger 4.0l from my grandfather. My grandfather didnt drive it much in the 6 years he owned it. We moved them back home last year and they had the truck parked under a tree. Of course, a squirrel came down and made himself at home nesting and feeding on spark plugs wires. I replaced the plug wires and noticed he had chewed another few wires and the pass side of intake. My brother started driving the truck and no lights came on in the four months he drove it so I didnt worry about replacing the other wires i had found chewed. While he was driving the truck the tensioner pulley broke. We replaced that and the belt, it started squealing. My grandparents took it back at that time. It sat for a few months then my dad purchased it from them.


Now we get into the current problems. My dad starts driving it on the regular. Belts squealing and pisses my mom off. Shes embarrassed to be in truck. Dad gets out noticed the new tensioner pulley had broke on the rear rib on pulley, just a tiny piece. He replaces that again and notices belt seems to be a little too big (one recommended from parts store) so he gets one an inch smaller. Gets it on no problem. Drives it for a few days squeal is gone. But the truck starts dying.

Thinking it's because the belt is to small, we replace it with the recommended one. Squeal is back and truck is still dying, some times at an idle, sometimes while driving, but especially in reverse. Notice the battery light is flashing. So I pull alternator have it tested. Idiot at parts store test the alternator off an explorers alternator setting 135a. Ranger alt is 95a. So it tests bad but it also only tested at 75a. So either way it's bad in both settings. Replaced alt. Truck runs fine for a day or so. Then starts dying when moms driving it. Shes mad. I tow it back to her house. Now it wont start at all. Checked fuel pressure thinking maybe fuel pump. Good. Checked fuel pump voltage. Good. Let truck sit for a day starts up squeals for a second drives and once it gets warm it dies. At a loss right now of whats goin in on. The wires that are chewed on intake, still haven't been replaced. We were told that its the knock sensor wires. We have another knock sensor and pigtails on order. Still dont make sense on why its dying.



HELP LOL I'm at a loss. Pics are of the wires chewed.

We had codes but my dad cleared them before writing them down. It was late at night and didnt wanna dick with it anymore. Imma be goin over today to run the codes again.....



True that on the parts lol my wife's explorer I replaced the starter 6 times in one day. Both autozones in my town had a batch of bad starters. They ended up giving me an upgraded one and no issues.

My credo
In theory, theory and practice are the same. In practice, they are different.
How old is the battery? What is battery voltage, engine off? What is battery voltage after the engine has been running greater than 5 minites?

Battery is just over two years old. 8/18. Havent checked battery voltage yet. Been leaning towards battery possibly being bad. Power steering pulley is chattering, too. I forgot to mention it in main post. Steering seems to fight alil more then normal right before it dies. PS pump is probably goin to replaced soon too.

Get one of the books with the wiring diagram. Don't guess what got eaten.... might be important, might not. I had a rodent eat some wires in my truck, turns out some of them were for a non-existent cruise control module, so no big deal. But I know what they are for. Beats guessing.......

First thing, don't trust the guy behind the local counter, dealership or otherwise; he's there to sell cheap parts at high prices & make boss happy.
Stop being random\chaotic, fix\replace obviously worn\broken\damaged items; make note of the TroubleCodes & trace problems logicly.
Install\replace a single item at a time, so to differentiate a problems source\fix.
Study the experiences of others, learn the specific issues for this truck+engine, shop around & choose+order good parts at a good price.
Make effort+time to do a good job installing parts, looking for other items that need attention, make improvement where you can.
Good luck.
