Vehicle chose today, when it was first in line in the driveway, and was about to be driven on a trip 4 states away, and nobody is open for the next two days, to have what appears to be a malfunction of the security system. (2019 ranger XL)

I have ordinary coded keys, no nonsense with key batteries etc.

So, I drove several places today, and then tonight, I start it up to go to the store before leaving tomorrow, and it started, ran for 3 seconds, then shuts down. No key will start it, it just cranks, with no firing. It seems likely to be the security, based on the way it started fine , ran and shut of that fast with no sound of bad running, etc. I had a security system malfunction happen with the S10 once, and it was similar, but it was a little different, it would start, and run 2 seconds. And on the S10, a light lit up to explain that the security system was activated. There seems to be no such light on the Ranger.

What is even nicer is that it is blocking in the other vehicles, with no place to push it to.

Not a great start for a new vehicle that I have had less than 3 months.

 

Got to ask..................do you KNOW there is gas in the tank, not what gauge says, do you KNOW

Engine should NOT crank if immobilizer is the issue, the starter is disabled when that happens, along with fuel pump and injectors

So it doesn't read like a PATS issue

You can get a 2019 PDF Ranger manual here: http://www.fordservicecontent.com/Fo...US_10_2018.pdf

Easier to search, maybe a fuse blew, although which one I don't know, Fuel pump maybe

You could try spaying ether(Quick start) into the engine just to test if spark is working

 

If there is no fuel, then both the pump I filled it with yesterday, AND the truck gauges are lying........ The pump claimed it put in 16.8 gallons, and I paid for that amount.

I have the manual, and spent a good deal of time looking through it. Nothing useful. Just a brief paragraph

The S10 would crank and start, but not run more than 2 sec if the security was triggered... I know that, it failed right in the dealer's lot.

This was JUST like what the S10 did..., and accords with the tiny scrap of info that was given somewhere in that mess of a manual, appearing to indicate that the vehicle would start but "not continue to run" if the key was not read right. In another place that appeared to be contradicted, but that also appeared to be for a slightly different circumstance.

I may have to track down the fuel pump relay and see if it has a twin running something non-essential.

 

You may be right

This morning, after I verified that the fuel pump relay is working, it started. It ran very rough, however, and ran only for long enough to move it back far enough to get another vehicle (not, however, a long-trip vehicle), out of the driveway past the trees.

It is showing both the SES and the powertrain failure lights.

 

Bummer

SES = service engine soon, right, so CEL

Don't know enough about the 2019 to be specific about the symptoms that trigger Powertrain(wrench) light

But in my many years of working with electronics, lol, I have found that unplugging the power on anything with a CPU, and then re-powering, letting it reboot its factory software, can fix a mistaken glitch in the system

i.e. disconnect negative battery cable, wait 5min and then reconnecting to see what happens

 

Yep..... "powercord reset". Works when the computer gets "off in the weeds". Does not address the root cause.

In this case, given the one start, then non-start situation before the lights appeared, and the fact that even when it runs a little, it does not have enough power to move the vehicle, it seems to be a "real" problem. I had it taken to the dealer, it's Ford's problem now. I'd not start off across country with a potential problem that I do not know the origin of, even if a "power cord reset" worked. SOMETHING made the codes appear, even if it is a bad ECU, or bad connection somewhere.

I like a problem to be positively identified and fixed by an action that SHOULD fix it. Just part of the "engineering thing", I guess.

 

Yes, I wasn't suggesting the reset so you could take it on a trip, just to maybe move it out of the way more

 

The issue seems to be a connector for the fuel pump that is somewhere under the bed of the truck. Dealer says it is over the spare tire, but there are no wires here that I recall, and the tank is forward of that, so I doubt what they say.

So far they do not have a connector, so it is still waiting for action.

 

Fuel pump issue would match symptoms

Not alot of details on wiring in the 2019 yet, but in spare tire area would be a stretch IMO as well
In later years of our older Rangers the EVAP system and wiring was behind the gas tank, so near spare tire, and combining fuel level, fuel pump and EVAP in one wiring harness would make sense, but not that far back under the bed

 

The rollover module was the problem.

All the way back on a crossmember. Engine should not have run, but it did run, just ran rough.
