Died. Cranks, but no start

[DD31]

2007 XLT EL. Died shortly after filling up with gas. Would not restart. Didn't have any tools on hand, but had fuel pressure at the rail (pressed the schrader). Had my scanner, but there are Zero codes.

What the hell?

Gasoline engines need 3 things to run: Air, Fuel and Spark
It's not air - we're still breathing
Fuel depends on the amount of pressure in the line
Spark - kill power to the pcm and no spark

Check all fuses for the pcm with a meter or test light

Is the theft light blinking fast or slow?

Went back with my fuel gauge. Pressure was good. It started right up. I let it idle for 5-10 minutes, no problem. Revved it to 2500 rpm, let off, and it died. Wouldn't restart again.

Its at a McDs parking lot so im not going to be out there for hours working on it. Getting towed in the morning

What pressure is "good"?
It is similar to when you go to the doctor. They check how many beats per minute your heart pumps, not if it is pumping.

What kind of scanner are you using?

Good, like good good........

Torque pro.

I'm interested to hear the outcome of this situation. When mine did this it was the fuel pump. Came out of the house one morning to go to work and it was all crank and no fire. Used the programmer for my Mustang to scan for codes, none found (although if I'd tried to start it enough times I might have found one eventually).

I had one like this. Navigator quit, no codes, no start even with starting fluid.

Changed crankshaft sensor, no more problems 2+ years.

The shop I had it towed to said they diagnosed it as the crank sensor. So we will see if thats what fixes it, but I'm guessing probably what it is. It sucks that it wouldn't throw a code otherwise its a fairly simple repair.

The really strange part is that it happened right after I filled up with gas, so that usually make you think it was something in the gas

Most fuel pumps in tank that have gone out on me, were recently after filling up. Don't know if it's just coincidence or not. I do know wrestling with a full tank is no fun. I did the one on my 86 Mustang, I drained off around 10 gallons or so, the silly mechanic at my work, did my 89 Lincoln. He didn't bother draining off some of the fuel, and he rocked the tank lowering it, splashing his work shirt big time. He wasn't a happy camper.

Sounds like the crank sensor would be a good spare part to have on hand.

Just ordered one for my '07, $22.61 to the door.

100% of the in tank fuel pumps I've had die were right after filling the tank, especially after running around for a while with really low fuel. Many of these pumps depend on the fuel for cooling with the pump at least partially immersed. Some use an open cell foam sleeve around the pump motor to wick up fuel when it's really low.

So on a nice hot day, been running around on fumes for a while. Then you pour in 20 gallons of gasoline at 65F, that's going to thermal shock the pump motor.

Well update time, the shop i took it to replaced the crank sensor and then couldn't get it started.... said they need to call in a specialist.... super

 

[stamp11127]

Well like the old Dragnet TV show....just the facts Ma'am.

Fuel Pressure is: need psi readings
Impulse signal from crank sensor: Y/N
Impulse signal from cam sensor: Y/N
Signals indicate timing between cam & crank is correct: Y/N
PCM firing injectors: Y/N
PCM firing coils: Y/N

It's so easy a caveman can do it.......but you just need the correct tools today.

Happy ending? I need closure .

 

[DD31]

lol. nothing yet. Their specialist is supposed to check it out today, so we will see. I'm almost to the point that I'm going to have it towed back to my house and work on it myself. Or strip it down and sell it for parts. One of those two

 

[DD31]

UPDATE. Crank Sensor.

Apparently the first one they used came from NAPA and was determined bad by the 'specialist'. The specialist got an OEM sensor and also replaced the wiring pigtail for some reason.

 

[stamp11127]

If the connector was bad that it required replacement none of the replacement sensors would "work" until the electrical connection was fixed. There may have been nothing wrong with the original crank sensor. Seeing that it was 11 years old it is a good investment to replace it before it would quit anyway.
Next question - how did they connect up to the existing wires? Solder and heatshrink, twist the wires together and electrical tape them or use the wonderful butt connectors.
