Have you done a fuel pressure & volume test? If the fuel pump is going bad, it will have the same symptoms. When was the last time the fuel filter was replaced? Are you sure it's a fuel related problem and not another sensor? I would get ahold of a scan tool and monitor tps, iac and some other sensors too. Make sure maf signal is reading good, those also get dirty and/or shorted out causing similar issues. Egr is another problem, if it's got some carbon stuck in the pintle, it will cause a lean condition.

Fuel Pressure Sensor ---at fuel tank ??

You obviously are not testing a thing if you
replaced it even once

There are a couple of reasons for your issue
& they have to do with the vehicles system strategy

You need a repair shop to look that up & then diagnose
according to a recommended proceedure to resolve

A bad fuel sending unit will make the car think your less
than 15% fuel in the tank & possibly reduce power or
shut off--on some cars it will,yours has to be looked up

SOURCE: my jaguar s type has

Had this problem on a v6 3l petrol. No codes present.Connected laptop to diagnostics and drove jag for a few miles.Found fuel pressure to start off at over 55 psi but slowly drop to 20 psi and less until car came to a halt.
Waited a couple of minutes hey presto car starts,pressure back to over 55psi running fine for a while.tested power supply to fuel pump,ok at constant 12 volt. Changed inline fuel regulator and fuel filter,still the same.Checked fuel tank for any possibility of a vacuum occurring,no not that either.Had to bite the bullet and change the in tank fuel pump,problem solved runs fine.This car had also been to jags and because no fault code appeared it must be alright! I have learnt that over my forty year mechanical experience that common sense basics must also be checked out and not totally depend on computer fault codes.Hope this Johnnyman.

Hi I think your problem is connected with your Air mass meter if you look at your engine from the n/side it is situated just after the air filter box it has a spring clip at one end a flat metal thin box with a lead attached and a jubilee clip at the other end. Hope this helps my 4.0 lt x300 did the same thing

SOURCE: car lost power and started putting out black

The rubber pipe feeding air from the intercooler to the bottom of the EGR valve is probably split - this was the problem on mine - exact same symptoms!

SOURCE: I have an jaguar s-type

The transmission is faulty - most likely one (or more of) the solenoids for the clutches on the planetary gears are defective and it jams the gearbox, causing the engine to stall.
You will have to put the car on a diagnose machine to find out exactly what part has failed. But replacing it/them will be in all cases a complicated and expensive job: they are inside the casing of the transmission and it will have to be taken off and dismantled to replace them.

SOURCE: car was starting perfect until wife tried to start

Hi Tony, If the car ran out of fuel the fuel rail will be empty. Pressurized fuel must fill the rail before injection is possible. The pressure of the fuel in the rail should be somewhere around three point eight bar. Crank the vehicle for about forty seconds at a time and then allow the starter to cool. Repeat until the car starts. A better method is to identify the fuel pump relay, remove it and bridge the switching connections, but that can be dangerous unless you have a knowledge of electrical circuits. Regards John

Engine temperature gauge not working

temp sensor on the engine needs replacing or the wire has come of the sensor. depending on the engine you have there are a few places where the sensor can be. some are on the back of the engine near to the clutch/auto box housing is on the engine some are on the return side of the water supply to the expansion take on the engine block, usually a single wire sensor, the ecu has an engine temp sensor as well this is a 2 pin type. usually these last longer than the single wire type, but it can be some times best to change them at the same time if you dont know when this has been change. replacing both can some times help with excess fuel usage, as ecu reads the temp as low and adds more fuel to the mix to heat engine, this also depends on the ecu settings if this does that. as some temp sensors are gust a guide and the other sensors take over when its not reading correct heat.

Car is using more significantly more fuel lately. new spark plugs cleaned MAF sensor. no obvious fuel leaks. car seems to be underperforming at random times. What's causing the increase in fuel...

a fuel pump will not increase fuel consumption unless there is a leak,which you say there is none.a change in driving habits can increase it without knowing the habits have changed.some times poor gas quality can cause this or when a fuel company changes its additives when switching from a winter type mixture to a summer mixture.if the thermostat hasn`t been changed for a long time this can cause an increase if fuel consumption,as the coolant sensor will send a signal to the computer that the engine is not up to operating temperature and it needs to increase injector on time(spray more fuel).a tired coolant sensor(rarely),the throttle position sensor(tps)can cause this(on rare occasions)possibly a partially plugged fuel filter as you have to push on the gas farther to get enough fuel to accelerate the car.

My 1998 buick park ave jerks when i press on the gas,the car has 85,000 mils,i have had my fuel pump changed and a sensor changed,but it stills jerks when i press on the gas,plus it stopped on me 3 times...

That sounds like a misfire. Change the spark plugs, your best value for those as opposed to the expensive ones listed in the manual are Autolite 105's. Get the copper core model and gap them to .060"
Also clean thoroughly or change your air filter and clean the throttle body. Also clean the MAF ( mass airflow sensor). That sensor is easiest to identify on your engine as the largest sensor and it is mounted into the top of the throttle body with two security type screws. If it is the original sensor it will also be labeled on the top with "ABC". Carefully remove the sensor by unplugging the wiring harness, loosen the security type screws and pull straight up. There will be an o-ring type grommet in the sensor mounting hole or it may still be attached to the sensor itself; don't lose it. It prevents air flow leaks.
To clean the sensor, look down inside the "shaft" part of the sensor. You will see two diodes. DON'T touch them. DON'T drop the sensor, or tap on it.
Use isopropyl alcohol that you can find in your local health&beauty department store sections, the 70% formula will work well. There's no necessity for special potion type expensive sprays or whatever that's on the market for cleaning your MAF.
Simply pour some of the alcohol over the sensor diodes and let it sit for a few minutes to dry. The diodes are clean when they look shiny. That is optimal and it getting dirty is commonly over looked on your particular it often does make very noticeable improvement.
Then it is ready to reinstall. Screw the it in by alternating between each one so that it mounts flat onto the throttle body; you don't want it to be able to leak any incoming air. Then before plugging the sensor wiring harness back in, now would be a good time to clean any corrosion or crud from the plug. You can use the same alcohol as before; pour on and let dry.

Code P0133-02 (o2 sensor slow response) keeps coming up even though we changed this sensor like 3 times. How can I get my car to pass inspection? It's been 3 days of changing sensors, changing brands of...

just because you have a slow response code does not mean that you have a bad sensor, the slow response code is just telling you that the fuel system is very slow to respond to fuel delivery changes, this could be caused by many different things it could be as simple as the oil is contaminated with fuel, it could also be a problem with the fuel pressure, could also be a vacuum leak. the fact that you keep getting the same code with different sensors tells me that the problem is not the sensor but the fuel injection system. there is a flow chart for the fuel system and i am afraid you are going to have to have someone run a diag. check on the fuel system.....SORRY

I am having a problem starting my car when it have sit for a long period of time like overnight. I would have to step slightly on the gas while turning the ignition key to get the engine to catch. When...

This sounds a lot like a knackered air valve. This valve regulates the idle speed. When it fails open, too much air gets in, forcing the system to richen the mixture ratio. When it fails closed, not enough air gets in causing you to make up the difference by stepping on the gas pedal. Depending on fuel system type (Bosch or Regina) it could also be a failing air mass meter (Bosch only) or a faulty MAP sensor (regina).

I see you changed the air valve, but did you check the connector for cleanliness? A low voltage on the connector makes it do weird things.

If the replacement air valve is known good, then that leaves the air mass meter (Bosch) or the MAP sensor (Regina). The 0xygen sensor is a PTC on the Regina system - so if you changed it make sure you got the correct type. Most Oxygen sensors are like galvanic batteries, not resistors, but on Regina fuel systems the latter type applies. It is just a resistor.

If you have a Regina fuel system (square ignitor on the driver's side) the MAP sensor will fail like this. Ensure the vacuum line is connected to it and the connectors are clean. If the system can't find the MAP sensor values, it guesses and you get a rich mixture by default.

If you made it this far, check out your ignition system - the crank angle sensor sometimes gets flaky and the ignition system starts to guess as to where Cylinder 1 is - and retards the timing, sometimes shutting off power to the ignition coil completely if it gives up.

Taking this one step further, the fuel pressure regulator could be bad - resulting in too high fuel pressure causing a rich mixture ratio.

Read the codes from the fuel and ignition system. This involves opening the Lego like cover to the diagnostic jack, driver's side. Position 2 is for the fuel system and position 6 is for the ignition system. You plug the test plug into each port respectively and press the button for at least one but not more than three seconds. Any blinking code other than 1-1-1 is a fault code. The system flashes the codes by blinking the LED, pausing, blinking it again, pausing, blinking one more time. For example, I have code 232 (Incorrect mixture ratio - 02 sensor at backstop) it would blink twice, pause, three times, pause, twice, pause and stop.

Always read the codes with the engine off and key in the ON position.

Good luck - take your time and don't waste money on mechanics' work you can do yourself. Not to knock any mechanics out there (I have been doing this work for 17 years!!) but some will take your money - best method to empowerment - DIY.

2.0d x-type 2005 Est. Starting problems when engine is warm

Ok, time for car school. The vehicle is operated by the computer, every electrical concept that is. When the engine is cold, it starts fine because the computer has placed it in "cold start mode", putting more fuel into the engine than normally would until Once the engine is warmed up, a temperature sending unit or temp sensor tells the computer to change to normal run mode. IF said temp sensor is faulty and is not telling the computer to make said change, it stays in cold start mode, still dumping excess fuel in the engine that is now not required, cause it's warmed up. Like keeping the choke closed on older vehicles. Now I think you can answer your own question, when this no start action is happening after warm up and it always starts fine when cold, what's the first thing you check ? Right, the unsuspected temp sensor. Change that and no more start problem. Have a wonderful day. Glad I could be of service.
