Sounds like the PCV valve might be clogged and has created a vacuum within the fuel line. A new valve will cost you about $15.00 US and is easily replaced. You will find it on the top of the valve cover, depending on the engine model you have.

You should also check the fuel pump and verify that it too does not have a vacuum and therefore is not drawing gas from the tank. The fuel pump is located inside of the trunk. When you turn the key to the on position, have someone listen inside of the trunk for the faint sound of a motor come on. If you hear the pump engage, then you might have a blockage within the fuel line.

To fix a physical block in the fuel line you will need an air compressor and a blower nozzle that will fit inside of the fuel line. To blow the fuel lines out, begin by removing the fuel line from the fuel pump at the tank, then remove the line from the backside of the fuel filter. Place the end of the fuel line that was detached from the fuel pump into a large bucket and somehow tape it in place so that it will not blow out of the bucket when you go to blow it out. Now take the compressor air nozzle and insert it into the fuel line that you detached from the fuel filter and GENTLY begin blowing air into the line and have someone watch the other end in the bucket.

Once you have air flowing freely through the fuel line, reattach everything and fill the tank with fuel (if it's still empty) and try starting the engine again. If you still have the stalling problem, more than likely the fuel pump is shot and will need to be replaced.

Hope this helps you out.

Cheers,

Keith

I have a 1989 Ford Crown Vic. Here lately the car will die going down the road. It will usually start right back up. SO, I replaed the in line fuel filter and it was fairly dirty. It ran great for a few...


Most likely the fuel pump,when the fuel filter gets that restricted,it most of the time,is not long before the fuel pump goes out,because of the strain on the pump.

1988 Ford Crown Vic Strange Idle


When you turn the key on does the check engine light come on? If not it may be burned out. It sounds like a MAP sensor or an O2 sensor is bad. I would suggest taking it to autozone as they do free diagnostic and seeing if a code comes up. If it is a sensor it should, if not it may be the idle sensor not reading right in the ECU. More than likely it is one of the sensors though.

1996 Crown Vic, Valve noise under heavy acceleration


No use what's in there, but have the engine de-carboned by a Ford dealer, or remove the octane adjust shorting bar located near the ignition module (retards timing 2 degrees), this will in most cases cure the issue unless there is allot of carbon in the cylinders. There are also methods of ing this de-carbon procedure at home, check on the internet for tips.
