Question about 2003 Jaguar S-Type

1 Answer

While excellerating onto the interstate vehicle just seemed to run out of gas with plenty of gas in the tank (no warning light or OBD readout) now it will not start. I was told that both fuel pumps went bad? Doesn't seem right, could it be inertia switch?

Testimonial: "There are two fuel pumps in this car, would they both go bad at the sane time? If only one went bad will the car continue to run?"

hi sometimes on most cars if lift up the back seat ther usually the pump unit on the top of the tank with two pipes coming out of it .if ypu can find the relay for the fuel pump connect the terminals 30 to 87 together you should hear the fuel pump run.alternitavely check the power to the fuel pump with a multimeter you should get 12 volt when trying to start also check for broken wirig to pump.

this is a old model and it should have a cold start valve or it should have a coolant temp sensor, replace the colant temp sensor which is usualy located on the thermostat housing or on the intake manifold and this will sove the clod start problema!!

if your fuel pump and relay are new, how about your fuel filter, if your fuel pump is working but no fuel turns out, check fuel pump polarity, if ok, there will be a clogging in fuel lines, take a high pressure air and plug it to fuel outlet in fuel lines test port, allow air to go back up to fuel tank and observe if the air goes, if not, check or change fuel line, if the air goes to tank, direct your fuel relay pin 30 and 87 and check if the fuel runs to the injectors, if not, change a good fuel pump

Plenty of wires run around the back of the engine and transmission. Sounds like you may have caught some in between the engine and transmission when putting them together. This would definitely cause a problem like this. I been there and done it.

Warning light for low fuel stays on

The sensor is part of the fuel pump module inside the gas tank.
The signal is sent to the body computer, so it could be a faulty module or a problem with the body computer.
The circuit would need to be checked with a meter.

What causes abs light to be on

The abs light being on indicates the presence of a fault somewhere in the abs system & the system has been disabled.
Fortunately the design of the system is fail-safe so that your brakes will work just as if you didn't have the abs feature. The only time to be concerned about safety is when the red brake warning lamp illuminates steadily.
There are self-diagnostic capabilities in the abs controller so you could have the memory of that unit readout at a dealer to learn what may be wrong with it. Lot of times it's just a wheel sensor.

Good luck, i hope this helps.

'Check Engine' is a general warning light telling you there is a problem somewhere on the engine. **Note** It is supposed to come on when you turn the key as it is checking the engine electronics. It should go off after a couple of seconds to show the system is working properly. If it stays on get a good auto electrician to plug it into a specialist diagnostic computer to find out where the problem is.

Did you have the vehicle scanned for codes?
If so what were the codes?
Gas cap has to be pressure tested. Looking fine is not gonna cut it.
If you didn't have the vehicle scanned go to Autozone they will do it free. Then get back to me and we will take it from there.

No Power sometime, Engine Light is Flashing

If fuel filter hasn't been done lately I would start there & if you can, have fuel pressure tested while your at it. You may have tired fuel pump but pressure test will confirm. If you recently filled up somewhere different last time you got gas, I'd also try some "Heet" or similar just incase you got a tank full with some water in it.
