Question about 1993 Jaguar XJ6

1 Answer

Fuel problem with my XJ6

I lost my gas cap and had to drive without for a week with something stuffed in the fuel tank opening. The check engine light came on and then the car shut down days after... The diagnostic code said it was fuel failure. Now it I can get it to start at all, it will not accept any pedal. If you press the accelerator pedal it stalls out immediately. I have changed the fuel filter, but beyond that am unsure what to do next. Any suggestions?

The gas cap is mostly used to maintain the pressure inside of the gas tank, and to keep the fuel pump from working itself to death. Sounds to me like your killed your fuel pump. Get the new gas cap, and have someone test your fuel pressure. I am pretty sure there won't be much, so replace your fuel pump if this is the case.

What happens when you drive without a gas cap


ok on todays automobiles the gas cap does more than just seal the gas tank. Now they run a return line to the tank. this does 2 things. it returns un used fuel and vapors back to the tank , and it pressurizes the tank to help improve the fuel pump.

Now as it is possible running without the gas cap may cause problems I am not 100 % positive that is your only problem.

It sound like the knock sensor is detecting the knock you mentioned and is trying to retard the timing to fix it . In doing so it has retarded it to far causing the engine to loose power and eventually stall. I would first replace the gas cap. then run a good gas additive to a full tank of gas to clean out any water and dirt that may have gotten into the tank while the cap was off. now the issue of the knock as you described. is it a knock or a ping? A knocking sound is loud metallic hammering noise. a ping is a ting not very loud. if it is a loud metallic sound I would have a reputable mechanic check it soon, as it could be a serious issue. Ping can be caused by bad or weak gas or cheap low octane gas. I would run a mid grade gas in it and see if it fixed the issue.

Major gas leak above spare tire


I think you have some rusty gas line, remove the spare tire and check the fuel line again.

Fuel pressure problems. If I remove the fuel cap truck runs normal. I've replace just about everything. And still have problems with it.


Have you actually checked the fuel pressure with and without the gas cap? If you have a tank venting (EVAP) system problem (e.g. blocked vent on gas cap, plugged canister, or one of the two vent valves stuck shut), you can draw too high a vacuum on the tank which will cause a fuel starvation problem.

I had asked about my jag smelling like it was flooding cuaseing it to bog out on me, it is a 1990 xj6 4ltr jag


Well your car is a fuel injected engine which means than there is a different set of problems.You still could have something as simple as a bad fuel cap or a clogged vapor return line to the fuel tank.A fuel injected car is really never supposed to "flood" as the computer controls the amount of fuel allowed into the engine via the fuel injectors.You could have a fuel injector seal bad which is allowing fuel to seep out and air to seep in causing the "bogging' effect when you press on the gas.If after running it,you pull the spark plugs and they seem very "wet" with fuel,then you could have a computer problem which is allowing more fuel than is needed through the injectors.Outside of the few visual checks for leaks and or hose dry rotting,if you are not having any check engine lights coming on,then you may have to have it checked by someone with a computer reader.Try and narrow down where the fuel smell is coming from if you can.The engine or the rear of the car.If it is from the rear,replace the gas cap.If it is front the engine,look for any visible signs of fuel,then check the plugs.

My 92 xj6 gas cap will not seal tight. i got another cap from the junk yard and it wont either im starting to think the problem is with the tank. What would cause two gas caps not to seal when u screw it?...


Did you install a new fuel pump? Because the fuel level sender is part of the pump. There are hoses that connect to vapor recovery from the tank check and make sure they are not lose. Take the cap off and clean where it threads in. I have seen where gunk builds up and does not let the cap seat properly because it isnt going all the way in.get a new cap at the dealership. I bought new caps at the parts store and the light still came on.got the correct one at dealer and as soon as i started my car the light went off .

Got scan problem numbr P0442 Check engine is


Po442 is an evap leak, this is the fumes from the gas tank, check vacuum lines from engine compartment for any cracks or splits also make sure gas cap is tight and gasket is good, most of the time this is caused from a bad fuel cap, i would replace the gas cap make sure its on tight then drive for a week if the light goes out then problem solved if light is still on after a week of driving then there a leak is the system. hope this helps.

Why si the check engine light on on my 2006 Chevy


Tighten your fuel cap 3 times to make sure its tightned. don't push it in when you tighten it. Use Fuel injection cleaner like once a month... You may have gotten bad gas. Don't use 100 percet gas. Use gas with ethenol... you get better gas mileage. I go through 3-4 tanks a week. I use the 87 octane and I put Berrymans Fuel injection cleaner in once a week. I don't know about your hesitations though I drive a 5 speed

CHECK ENGINE LIGHT COMES ON


My guess is you have a leak either in the fuel tank itself or in the plumbing from the cap down to the tank. Have you ever been in a wreck?

When fueling the vehicle, do you see any gas leaking out under the vehicle?

Does the area where the gas cap screws in have any damage that would allow a leak to occur?

Another area to look at is the system that recycles gas fumes back to the gas tank.

Something is not allowing the tank to hold pressure.

93 xj6 stalled at a light, can't be driven


The first thing I would check in a situation like this is the Fuel Pump.

Your fuel pump is physically inside the Gas Tank (which is located between the rear seats and the trunk/spare tyre).

However, the control unit for the fuel pump/motor is right on top of the tank. My experienced mechanic gave mine a couple of bumps with a small object (like a small pipe to reach the box) to kick it back into operation.

Here's a quick 15 minute test:

Try this: keep the tank -Filled Up- this will help to cool the Fuel Pump which sits in gas inside the tank.
-Put your keys in the ignition and turn to stage2 (right before you begin to turn the engine over),
-Go around to your trunk and give the Fuel Pump a couple bumps with a tool that will not hurt it (it is covered in solid plastic).
-Then try cranking the engine while pressing down on the gas pedal, one of three things will happen, 1) The engine turns over and everything is gravy! 2) It cranks but doesn't start up 3) It cranks but doesn't start and you can smell gas from the engine bay.

If #2 is you: then your fuel pump has hit some scummy **** and doesn't want to work without repair or cleaning, try giving it another knock or two with the electrics in the car turned on. Maybe have a friend crank the car while you -tap- on the fuel pump.

If #3 is you: Check your spark plugs, they could be misfiring.

If all above fails I would start thinking that you engine idle valve is dirty and needs a quick clean.

Best luck!
