Question about 1995 Jaguar XJ6

6 Answers

Starting problems at times

Already replaced fuel pump and filter.
AT TIMES , the engine will fire on 1 or 2 cylinders and quit. This will then happen repeatedly and engine will not start UNLESS I "pump" the gas pedal, then the engine will run extremely rough (like the timing was off) but if I keep "pumping", eventually the engine will suddenly "rev" to a high RPM. At this piont, it will run fine all day, unless I turn it off. It then MAY start perfectly, or I may have to do the "pedal pump" procedure.

Last week, prior to the fuel pump being replaced, it would not even fire at all AT TIMES. If I tried a day later, it may or may not start perfectly.

At any event, once the engine has started and is running correctly, it works perfectly.

Car has 107K miles and appears to have been well maintained.

Please help.

It sounds like your injectors and timing belts are not working properly, this happens not only to old cars but some new cars. you may also have a problem with your computer. my advice is to go to a certified mechanic and have it checked, as opinions on here may work, but may als cause you more damage if there is more wrong with he car then you think. hope this helps.

Check fuel pressure, injectors and ECU.

    I would exclude any problem related to the timing belt, as this will give you troubles even at higher rpm, not only on start.
    Dirty injectors can cause similar problems.
    Not combusted fuel clog the injector when you turn off the engine and you have then troubles on startup.
    About the fuel pressure, well if you just replaced the fuel pump there should be no problem on this side, just check the tubes for obstructions, and check fuel filter.
    A problem with the ECU can also give you troubles of this kind, to diagnose this kind of trouble you will need to take it to a garage, they will get an error code in return from ECU so to diagnose the fault.

Some times engine will not start i have to turn ignition of &on several times before starts fuel pump and filter been replaced. there is plenty of fuel preasure. fuel is reaching cylinders


What make , model an year vehicle ? You need to explain a little better what's happening ! When you turn the key to the start position what happens ? Does the starter spin the engine ? The engine doesn't start an run ? A crank no start or no-crank no start ? How do you know there is plenty of fuel pressure ? Did you hook - up a fuel pressure gauge ? An how do you know fuel is reach cylinders ? Did you do fuel injector fire test ?

Could be number 1 and 2 injectors are now blocked.

I suggest you go back to basics and ensure the ignition system and compressions are sound. Coincidence seems to happen quite a lot with car troubles.

If all else fails it will be time to check those injectors. It is sometimes possible to position them so the spray can be observed or numbers 1 and 2 could be fitted in the 3 and 4 positions to check the misfire follows or simply remove the injectors and take them to a specialist for testing.
If the injectors are found to be blocked it would be best if the fuel lines and the fuel rail, pressure regulator are also flushed and thoroughly cleaned as well as the pump, filter and tank.

I ran out of gas and now it wont start its turning over though


It is still quite possible that after numerous attempts to pump fuel up to the injectors it may not start. I am assuming there is no problem with the fuel pump and you can hear it operating when the ignition is turned on.

If the vehicle still will not start, it is possible that debris in the fuel tank has been picked up when the gas was very low and has caused a blockage in the supply system. The likely place to begin is the fuel filter. Have the filter replaced. You should also check the fuel line the other side of the fuel pump to ensure that fuel is passing through the pump towards the engine. When disconnecting the fuel line, fuel should flow out.

When you get the car started ensure you buy a bottle of fuel injector cleaner (reputable brand) and add it to a full tank of fuel during filling. Tip in the injector cleaner and then top up the fuel tank to full or near full. This should be done a couple of times a year in any event.

This sounds like a faulty fuel pressure regulator. It could also be a clogged fuel filter. I would replace the filter first, as it is good routine maintenance anyway, and then monitor the fuel pressure at the fuel rail on the engine. Many auto parts stores will rent you a tool for this. If the pressure is inconsistent, it is probably the regulator. If the pressure is significantly under 50 psi or rises gradually when the engine is off but the key is switched on, it is likely the fuel pump.

If you are getting spark then it may be a fuel pump problem or fuel pump relay or inline fuse. Always start Fuel system troubleshooting by replacing the fuel filter or filters! You may be able to apply 12 volts from the battery (use a fused line) directly to the 12 volt side of the fuel pump and listen to see if the pump runs. Also may need to check that it is getting a good ground to the fuel pump. Then if the fuel pump does not run independently, replace the fuel pump. The fuel pump relay is computer controlled and several other things give the computer inputs which then controls the voltage to the fuel pump relay.
