HI, just got a used ranger 2010 sport 2 months ago, have had no issues until 4 days ago when it stalled going down a hill in 2nd gear. we thought it was the fuel pump at first , but after more diagnostic, they changed the coil and replaced the engine fuse, then got a stern lecture to not let my gas get below 1/3 of a tank. I got it back and was told I needed to use my 2nd gear on hills to save the back brakes and then it stalled again on a slight incline...... changed the fuse again
and then today I was given a handful of fuses and told to drive it around in drive not 2nd..... made it 20 feet from the garage down the hill on a bumpy back road to the main road to have it stall again. I'm assuming it's not grounding somewhere. wondering if anyone has any suggestions to deal with this gremilin.

 

Welcome to the forum

2010 Ranger
2.3l 4cyl, or 4.0l V6?
2WD or 4x4?

And what fuse is blowing???????
There are many many fuses in engine fuse box and in the cab fuse box, be specific :)

Never heard of not running any vehicle below 1/3 tank, not sure what thats about, I think someone was pulling your leg

Downshifting to 3rd or 2nd saves front brake pads, rear brakes only get 30% of the braking power from brake pedal, front get 70%, on all pickup trucks, just FYI
On cars and SUVs its 60/40

If you are having a hard time IDing fuse go here: https://www.ranger-forums.com/genera...1-models-3747/

Get your 2010 owners manual, it has fuse diagrams and names and numbers

 

hi the fuse that is blowing is 44 15 amp : Ignition coil, Capacitor. they replaced the coil. the first time and second time it happened was when I was in 2nd going down a hill and the second time it was in drive also going down a hill as per what the mechanic had recomended.

 

its a 4.0 v6 4x4

 

Fuse 44(15amp) in engine fuse box only powers the Coil Pack so if it blows then the wire is shorting out, since you replaced BOTH the coil pack and capacitor, that would indicate it has to be the wire.

Going downhill is an odd symptom but not really relevant unless the wire is loose and shorting out when truck is at an angle, long shot

You need a volt/ohm meter
Pull out fuse 44
turn key on
Test which slot for fuse 44 tabs has 12volts, thats the "power side" of the fuse
The other slot is the LOAD side, and it has the short causing fuse to blow

Key OFF

Unplug coil packs 4 wire connector
There should be a purple wire on that connector, thats the wire from fuse 44
Set meter to OHMs
test ohm reading from fuse 44 LOAD slot to the purple wire, should be 0 ohms, direct connection, so thats the right wire
Now test ohms from fuse 44 LOAD slot to battery Negative(ground), should be N/C, no connection, or no change in meter
With meter still connected to fuse 44 LOAD and Ground, move wiring harness around to see if there is an internal short, meter OHMs will change if there is a short inside harness, OHMs will drop

Short could be under fuse box or at engine end of that wire, you need to find it

 

hi hi, we located a wire that was grounding out from the harness. I think we found the issue. I've learned alot about my vehicle in the last few days. yeesh.

 

Good stuff
