Hi, i have problems with my xj6 s3. When i test the fuel injectirs, they all squirt at the dame time, is this correct? Alsowhen i take the spark plugs out no fuel comes out when i chern it?

Hello,

Assuming your spark plug firing order is correct after the coil pack replacement and your plugs and plug wires are clean and connected properly--and you have gas in the vehicle--I am thinking Throttle Position Sensor (TPS).
To test the TPS you hold the throttle pedal to the floor and start the vehicle, if the vehicle starts you need to clean or replace the TPS.

If the vehicle will still not start and everything was replaced on the vehicle as the parts came off of the vehicle--and the vehicle ran before think:
Compression: Washed cylinders (pull plugs and squirt clean oil in spark plug holes (one-two squirts).
Fuel: pull hose after fuel filter and crank vehicle
Spark: Pull plug wire and arc with screw driver when cranking engine. New coil pack could be faulty.

You may need someone to crank the vehicle (mind your hands) while you test. You should be able to find videos for spark testing.

I hope this helps.

Determine whether or not, fuel, spark, timing...

Fast way start with a two-three second squirt of starting fluid. into the air cleaner then attempt to start. If the spark and timing are correct, it will run for a few seconds then quit indicating you have a fuel problem.

If it backfires, you have a timing problem. If it does nothing but crank, you have a likely spark/ignition problem.
Once you determine which it is, then you have a basis to determine where the exact malfunctioning part is.

can only be 3 things, bad motor, bad spark and bad fueling, in that order.
and 3 tools to check each, in that order.
ever do the 60k tuneup, (I have 4 of these cars restored and 3 sold)

my guess is fuel pressure good means it passes the squirt test
right? this is no carb, EFI needs 30psi, and squirt tests tell you near nothing.
Ponder this. if the motor had 170psi compression
and the spark was good, (it will be tuned up)
and is timed, right. is it?
then it will run perfect on test fuel. does it.?
if yes , then you have fueling problem , once this is proven, we work fueling hard.

Some of the basics to check.
Listen to hear if your fuel pump turns on.
Test fuel pressure. There is a valve on the fuel rail that looks like a tire valve. Put a rag over it and push the valve in. Did fuel spray out?
Do you have spark? Remove one spark plug from the engine. Connect the wire to it normally as it would be connected in the engine. Lay the plug on a bare-metal surface of the engine. Try to make sure the threads touch metal. Stand back a step, and do not touch the engine during this test. Have someone turn the key and crank the engine over a few times. Do you see any spark jump the gap? You may need darkness to do this test. No spark on any plug means the coil pack is dead.
Get some starting fluid and give a little squirt in all the cylinders. Remove the plugs one by one, and squirt it in, reinstalling the plugs as you go. Turn the engine over again and see if it fires. If you get it to fire like this, you have a fuel problem. This could be anything from a bad pump, to a broken computer that isn't telling the injectors to open.

Hope that helps.

Well fer a start ya can't jump start an automatic, only a manual. Now Jags are notorious for this kind of behaviour as they are pommy cars and we all know what the poms are like, so any way remove one or two spark plugs an git yer sel some Aerostart or similar an give it a good squirt down into the cylinder head, screw ya plugs back in, connect ya leads then kick her in the guts and vroooom yer of and runnin again..

A firing problem can be one or more of several things:

The engine may not be getitng fuel.
The coil could by faulty.
If the coil is fine, the spark plug wires may need to be replaced.
The timing could be off.

To test if fuel is pumping to the carb, unscrew the incoming fuel line. It will be the one with a bulky silver connection attacted to a small tube leading into the front of the carb. Place a bottle over the end to catch gas. Have a buddy turn the engine over. Since the fuel pump is manual it should squirt gas out. If it does then you're ok. If not, you need a new fuel pump.

The coil can be tested by removing the middle wire from the distributor cap which is just behind the carb. The middle wire should lead to the coil. With the wire attached to the coil, hold the other end of the wire by the rubber boot and place it near a grounding surface such as the block of the engine. Have your buddy turn the engine over a couple times. If there is an arc from the wire to the motor then the coil is doing it's job. If not, you need a coil. You can test all spark plug wires using the same method except unplug the wire from the spark plug.

If the timing is off then the truck could be sparking before or after the gas is squirted in. The truck should still run, so check the other problems first, but your timing should be check by a mechanic when you get it running.

Hope this helps!

Take a spark plug out, reconnect it to the spark plug wire and check for spark at the plug. Repeat as many spark plugs as you can. If you're sure it's getting fuel, you'll need to do a compression check, or make sure the tiiming is still correct. By the way what test did you do to determine fuel delivery is alright.

Fuel pump is bad or plugged fuel filter it seems. Crack the line from the filter leading towards the engine first. If gas starts squirting out fast, you have good pressue. If not the filter is plugged or a bad pump. How old is the fuel filter by chance? If original its plugged up by now

Does it even try. (cough and sput) Will it start if you spray carb cleaner in it?

Check for spark at the cylinders you mention. Unplug the wires from the spark plugs, put a spark plug in the end of the wires, and attach the body of the plugs to earth, or an exposed metal part of the engine. With the engine running, you should have spark at the plugs. If no spark, get the ignition system tested. If there is spark present, and you think the fuel is ok, then the compression must be at fault. The things that are required for combustion are: spark, fuel, and compression. Get a compression test done on the engine, but first check for any vacuum leaks in the inlet manifold around the cyl 5 and 6 area.
