  post locked   2005 Ford Crown Vic will crank and won't start  

Year: 2005
Make: Ford
Model: retired Crown Victoria (Police Package)
Engine 4.6L V8
Mileage: 129,000

Beginning about 3 weeks ago the car would not start. Turn the key to the "on" position, the fuel pump would engage/prime turn the key to "start" the car would crank but not fire. I then changed the fuel filter hoping that was the issue. After the filter it fired up but blew out a big cloud of white smoke that smelled of fuel, idled rough for a bout 15 seconds then planed out and smoke stopped. Seemed fine, drove the car all day and no problems.

Next day wife goes out to take the car, no start. I went out turned the key to the "on" position three times, each time hearing the pump prime then stop as usual. Car started. Same white smoke and rough idle for 15 seconds then planed out and ran fine.

Since then it would go a couple of days then start acting up. Not always blowing the smoke, not always requiring the key to be cycled before start.

Saturday we went to go get lunch in the car and as we were going up a hill the car died (first time for that). I coasted it to a stop and then finally after several attempts got it started and we went back home to grab our other vehicle. Now it will crank but won't start at all, this morning I got it to start once but since then nothing.

I removed you signature from this post. You need to delete it entirely. Links and advertising is not allowed.


Check your oil level and see if you are getting a fuel dilution in the oil.

If that looks good, see if you have lost any coolant.

  LETS start with the BASICS...

Is the CEL (check Eng Light ) on - has it been on ?
Confirm that it comes on when trying to start - then goes out @2seconds?

Your description of key on key off to start would have me doing a fuel pressure test use a gauge post the readings... Pressure is critical for FI engine...... THEN with KOEO (key on Eng OFF) observe the rate that the pressure drops...

Those items computer and pressure should yeild some information- Next would be a check for spark several plugs.
If this is a COP (coil over plug) the tests Are a still something you can do...a little more time consuming

As for the white smoke - Its cold out most plaaces SO I would hold off thinking it is a critical indicator, you could let us know- are you loosing coolant? is there evidence of gas in engine oil?

I think the smoke may be a key factor. It may be loading up on something after hot shutdown.

Thanks for responding so quickly Hammmer Time.
Coolant was a tad low (about 12 oz. of water added to get it to the full mark).

Oil is at normal level.

Inside of oil cap has no real condensation on it.

Kev, thanks for your help.

The CEL goes out after 2 seconds.

I'm pretty sure that the 2005 CVPI is a non-return system. Not sure if that info is important here, but thought I'd throw it out there.

When I pulled the filter a bit ago to check and see if the gas was OK and not loaded with water or trash I noticed that the tank side didn't have a ton of pressure.

I'll have to source a Fuel pressure tester, that will take some time. But I'll do so and post.

As to the coolant, no. It was a bout 12 oz. low but honestly I haven't even thought about the coolant in roughly a year. I did a fluids check last spring. The oil was changed about two months ago and is still on the full mark, doesn't smell gassy that I can tell.

I think you may have a little trouble doing that. I don't believe this car has a test port but it does have a fuel pressure sensor so you can read the fuel pressure through a scan tool.

Cool thanks. It'll be Thursday or Friday before I jump back in this one. Tomorrow is supposed to be in the 30s and snowing and the car is in the driveway, not the garage.

Hey Hammer Time.

We just now got good enough weather to go out and do something to the Vic. Saturday we put an OBD 2 tester on the car and got a "Cylinder Head Coolant Sensor Out of Range" error. Funny that it didn't pop a Check Engine light. I'm guessing that the senor went "Hot" when it failed and possibly that is why if had a no start condition. In any case, a $20 sensor fixed the issue.

Thanks to all that responded with ideas! Cool

It most likely went open circuit which would show the computer -40F which would make the mixture extremely rich.

Glad you found it anyway.

Closing the question now to keep the spammers our

A cooling system failure such as low coolant or coolant loss could cause an overheating condition. As a result, damage to major engine components could occur. Along with a CHT sensor, the fail-safe cooling strategy is used to prevent damage by allowing air cooling of the engine. This strategy allows the vehicle to be driven safely for a short time with some loss of performance when a overheat condition exist.

Engine temperature is controlled by varying and alternating the number of disabled fuel injectors. This allows all cylinders to cool. When the fuel injectors are disabled, their respective cylinders work as air pumps, and this air is used to cool the cylinders. The more fuel injectors that are disabled, the cooler the engine runs, but the engine has less power.

NOTE: A wide open throttle (WOT) delay is incorporated if the CHT temperature is exceeded during WOT operation. At WOT, the injectors will function for a limited amount of time allowing the customer to complete a passing maneuver.

Before injectors are disabled, the fail-safe cooling strategy alerts the customer to a cooling system problem by moving the instrument cluster temperature gauge to the hot zone and a PCM DTC P1285 is set. Depending on the vehicle, other indicators, such as an audible chime or warning lamp, can be used to alert the customer of fail-safe cooling. If overheating continues, the strategy begins to disable the fuel injectors, a DTC P1299 is stored in the PCM memory, and a malfunction indicator light (MIL) (either CHECK ENGINE or SERVICE ENGINE SOON) illuminates. If the overheating condition continues and a critical temperature is reached, all fuel injectors are turned off and the engine is disabled.
