Starting Problems// Stalling at Highway Speed 05 Ranger


Today I filled up with gas to travel back to upstate new york. At the fuel pump I filled up at the same station I usually do, and I went to get in my truck to start it, and there was nothing. The engine cranked and cranked but there was just no starting.

Eventually I waited a few minutes and pushed the truck away from the pump. I tried to start the truck a bunch more times, and nothing. I then pressed the reset switch for the fuel inertia pump, and then the truck reluctlantly started.

The truck finally started, and then about 110 miles later, while driving at about 45-50, the engine stalled on me, there was no response to pushing on the gas at 45-50 and then soon enough the engine stalled. I was greated with the oil light, and enigne light (normal I guess for an engine stall). I tried to start the truck again after pulling off to the side.

I got nothing, until I pushed the fuel intertia switch button. Then the truck started right back up. Truck then later this evening has started fine and ran fine.

Now, I don't know if that switch is actually doing anything when I push it or iff it is a fluke, but what could be wrong with the truck? It is a 05 with about 62,500 miles on it.

Any common problems that could cause this? Any one else have this problem?

if it keeps working after pushing the switch i would guess it is something electrical. Maybe try unpluggint he battery for 30 minutes and see if that helps by resetting the computer. just a guess.

My truck has been doing the exact same thing as you have explained for the past week. I have same engine and year ranger with roughly the same amount of miles. I was curious to see if you figured out what caused the problem or you if you got it fixed?

Ive been having the exact same problem with my 05 edge. It stalls on me a bunch with the lights and oil lights lit up, also the steering gets really hard to turn. Then i just pull my truck over and push that inertia fuel switch you are talking about (on passenger side under glove box) anyways once i push that switch 2 times my car starts up fine. it seems for me that switch is really sensitive and it is used incase of a car accident, it will notice if you suddenly come to a stop or something hits you from the front that switch will shut off the fuel to the engine and turn your truck off, so it wont explode!

in my case this switch is either defective or way to sensitive, not sure and this maybe happens 3-4 times a month, it used to happen a lot more. I brought this to a mechanic shop ive been going to for years and i paid a few hundred bucks, they replaced some sensors and did some fixing up. It didnt happen to me for about 6 months then recently, last 2 months or so.. this has been happening

EDIT: i have 54k miles also

when i bought my 1st ranger
i asked for clarification of this function .
i asked if the sensor is mounted inside the kick panel
( the mechanic`s reply )
no , the sensor is mounted on the side of the fuel pump assembly??????

who in their right mind would mount that sensor on the fuel pump assembly
if it is really mounted there

My 05 Ranger's Fuel Pump Inertia Switch failed so I just put a 15a fuse in place of it. It kept on triggering the magnet and stalling the engine and they wanted something like 150 bucks to get a new one. It got so annoying, I pulled the fuel pump and everything. Eventually the switch completely failed and the truck wouldn't start so thats why I put the fuse in place. The truck now runs and drives GREAT.

I also have an 05 with the same number of miles that is having the same problem. I wonder if there is a TSB for this issue?
