20 Most Recent 1999 Ford Crown Victoria - Page 4 Questions & Answers

Real simple Put a professional scan tool into the under dash connector Road test Look at data & then properly diagnose ANY problems & resolve Why a local shop or a dealer is stumped is beyond me IF-you do a cylinder leak down test & have no mechanical valve sealing issues Then you use any evap smoke machine to check for vacuum leaks on the entire vehicle You then look at & test all electrical system items needed Then you review all emission monitors,fuel trim,fuel pressure, oxygen sensor voltage & much more Cylinder misfires etc You do two thing You get all the data avail with & without a road test from the scan tool Then you must component test using an oscilloscope until some problem is found I believe not much that should have been done was regardless of order or sequence So far no one tried to find a problem or had the knowledge to do so You may simply have a worn out & blocked exhaust converter They last a long time but not form 1999 to 2014

On your dash the letters CO or CS show in the Distance to Empty (DTE) information center. there is a problem with the fuel level indicating system. Most likely the Fuel level sensor has failed, or is not completely as accurate as it needs to be for the DTE function to work. The fuel level sensor would most likely need replacing. Replacing the sending unit requires removing the fuel tank. If you choose to repair this issue i recommend replacing the fuel pump and strainer while you are there.

either your air filter needs to be replaced or your muffler and pipes are blocking air from excaping

it maybe a vacuum leak pcv hose near throttle body, or the intake manifold gaskets have shrunk causing vacuum leak

Google a copy of your owners manual & look in there Otherwise ask a dealer to help I said ---ASK--- NOT--- fork over any money

Have the battery load tested

Sounds like possible bad blend door actuator cor temperature control. They're very common concerns with these cars.part is fairly cheap, down side is the dashboard has to come out, it can be done without removing dash,but you need to find someone that is familiar with these...

Can't solve the problem without getting codes from scanner, but you should absolutely not drive a car with the check engine light "flashing" as this is an indication from the computer that serious engine damage will occur if you continue driving. This is with any car with a flashing check light.

that bearing in the pully is good for freezin up. wen it does the belt brakes from overheating.. i've done 3 over 5 year time. releeve tension on pully and remove belt. remove tthe 1 bolt in middle of pulley.then go in reverse.spray w/good lubricant.

Those are Oxygen Sensor Codes, you can google & look up They need to be replaced every 100,000 miles, but won't cause a no start condition or be effected by outside temp Spark Plugs -- have to be replaced every 3 years,can't just drive until you have a problem Sounds like lack of Preventative Maintenance to me Too many items to check or test ,to go into here

on the 99 crown victs dennis they had issues with the wiring harness where it fastens to the fuel pump in the tank! wiring gets hot!! and breaks connection that would be where i would go first

The groove where the clip fits is worn. There is excess force being exerted from the spider gear.

Sounds like you're on the right track. Check to make sure it's getting fuel at the engine. And also check for spark. Also make sure battery cables are clean and tight. And don't overlook the bottom ends, they're exposed to grease, grime etc... and EVERYONE overlooks those,

Pull the plug for the injector. Use an ohm/volt meter to check the ohm's of the injector, should be about 12.5, but 11 to 15 is in range. Also check the plug, should have 12 volts on one wire with the key on. Let me know. Randy

I would say no. The intakes are completely different on these cars and I have found the bolt patterns for the intakes are not the same and that probably goes for the exhaust manifolds also.

Blew a fuse in the fuse panel by your left foot sitting in the car. Look in the owners manual to see which one is the lighter fuse. It's usually a yellow 20 amp fuse.if you pull it out and look at it,you'll see a wire that loops inside it. If the wire is broken,replace the fuse and keep the screwdrivers out of the lighter socket.Good luck!
