Car dies out and gages dont seem to work when it finally startes got a check engine light and theft checked fule at injector rail got good pressure and fule pump works fine. Disconected batery for a half hour and hooked back up started back up idled high went arround the block a few times and it died out. stared up after sixed time but gages were not redgestering, also had service ligt and the theft ran but felt like it was been weighed down and when in park it would idle for a few minutes and then die out please help like car dont want to get rid of it thanks.

This issue requires a lot of careful troubleshooting. You really need a fuel pressure gage to start. You check the pressure with the key on and then while it starts and finally after it dies. If the pressure is good, then you measure AC volts at the injectors while cranking, while running, and as it dies. You should read a few volts, and it should stay the same or increase until it completely stops running. If the volts go down, after it starts, you then check just the DC volts on the positive injector terminal with the other meter lead on chassis ground. Again, the DC voltage should not decrease after the engine starts. If anything, it should increase to 14 volts and then drop back to 12 volts only after the engine dies.
If all of that is good, you have fuel.
Next look at sparks.
Remove one of the wires from a spark plug, stick a phillips screwdriver in the boot to connect it to the terminal. Then hold the screwdriver by the insulated handle and hold the metal shank about 1/8 th inch from engine ground, such as the cylinder head. Watch the sparks carefully as someone starts the engine. Do the sparks continue as the engine starts to die or do the sparks stop before the engine stops?
If the sparks continue until the engine stops, you have fire.
Now the only thing left is the air.
Will the engine keep running if you press on the accelerator? If yes, the problem may be with the idle air control valve.
If all of these things are working correctly, the problem is very difficult to find.
If either the sparks, fuel pressure, or injector voltages drop off after starting, we can find the problem in the next step.
Let me know the outcome of these tests before we do that.
If you don't have a fuel pressure gage, you can run the other tests first or borrow a gage from autozone.

If it cranks good but won't start, check the basics. Have a helper it while you check for spark at the plugs, if spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse.
I don't know liter size of engine? Sometimes checking spark may be a little more involved if no spark plug wires.
When checking fuel pressure, if no Schrader valve on the fuel rail, then you tie into the supply line to check fuel pressure.
Any applicable trouble codes? To check codes yourself, at the least, you need an obd2 code reader.

Seem's like your fuel pump isn't able to keep the good fuel pressure.

Might be a good idea to check your fuel rail pressure. I assume that it drops before your engine dies!!!

If fuel pressure is ok in your rail, try cleaning the fuel rail and injectors. Sometimes dirt can go from a trashed fuel filter an clog yor rail or the injectors.

What is the fuel pressure when the engine is running ?
Has the filter been replaced ?

check the fule presure on the injector rail is a what looks like a car tyre valve connect a gauge up to this or buy one ,i use a old AC filler pipe for one of them gas can things with the end changed to a tyre valve pump end and it works ok better than paying a lot of money for one ,should read 55lbs and if the pressure drops then suspect the gauze filter on the bottom of the pump first before you replace it as its a complete unit and around 600euros as its only available from the dealer

Hi Fabio:
Some check engine or anti-theft light there? We will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the car to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should! Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition.

Also, keep in mind that CKP sensor could be failed; scanned the PCM for fault codes stored.

Hope this helps.

Thank you for using FixYa, have a nice day.

Are you sure you have correct timing? its definetly a fule problem, if timing is good then turn your key to the on position and try to listin for the fule pump to prime. While the key is in on position go to fuel rail, there is a valve on fule rail called sharader valve. Get a small screw driver and press valve in to check if car has fule pressure. if pressure is present then it is incorrect timing or possible bad cam sensor.
