Check for bad ground to the injectors make sure any ground wires or ground straps get put back and fastened securely also if you have too much fuel pressure in the line the injectors cannot open the higher pressure puts pressure on the pintle valve and its not strong enough to open until the pressure falls lower

Out of the blue . truck looses power and wants to die. not letting it die by hitting gas peddle it runs but starts back firering supper bad. truck dies .starting up it doesnt want to put . made it home .....

if you have replaced cap and rotor plus coil and it seemed to fire up then i would take the next step. For sure put your new plugs and wires on then make sure you have replaced your air filter, and change out your fuel filter, fire up the vehicle if it doesn't start I would suggest changing the fuel pump. If it starts up make sure you put in some BK fuel injector cleaner in your fuel it might be you have dirty injectors. If all fails then get back with me and we will look else where. Good luck hope this info helps you out

92 vw passat 2.0 16v wont start.

I bet it's the gas. After some time the gas will no longer be volatile enough to start the car. Try draining all the fuel and putting in some fresh gas. Remember, when you try to start it again you'll need to get the new gas through the pump and lines before it will start. Also, check the condition of the injectors. Old gas can start to break down and build up a film that could be on your injectors (or clog your fuel filter- better check that too). Hope this helps.

Engine wont stay running. Please help.

change the filter first. IF the pumpwas bad it wouldnt start at all. It could be going bad but the only way to really test it is to pull your gas tank and at that rate you may as well replace it.

you could have a clogged injector causing the lack of fuel as well. you can try injector cleaner, Lucas is my personal preference I use it at every fill-up. 4-6oz per tank of gas depending on your tank size.

POOR GAS MILEAGE

Have you changed the fuel filter? I know it sounds weird but a plugged filter will make a truck use more gas. The computer tries to compensate for less fuel by commanding the injectors to open longer. Also a plugged filter will cause excess back pressure on the fuel pump making it loud.. Good Luck.

Car turns over great will not start

IT DEFFO SOUNDS LIKE LACK OF FUEL, BUT FOR IT NOT TO RUN AT ALL UNLESS THROTTLE IS FULLY OPEN DOESN'T SOUND LIKE AN INJECTOR, MORE LIKE NO FUEL AT ALL, LIKE THE PUMP IS KNACKERED. PULL OUT AN INJECTOR, PUT IT IN A GLASS JAR, THEN TRY AND START IT, IT SHOULD GIVE A BIG POWERFUL SQUIRT OF FUEL, TRY ALL THE INJECTORS ONE AT A TIME, BECAUSE ITS QUITE RARE FOR ALL THE INJECTORS TO GO AT TE SAME TIME

1996 cadillac deville want start

If you had a strong stream of gas shooting out then you may have an fuel injector problem. Possibly a clogged injector or bad injector.If the stream of gas was weak replace fuel filter first and test again.If problem persists check pump fuse then replace pump. sorry for miss reading your post.

Help w 1994 chevrolet truck

This injector set-up needs a specific fuel pressure supplied to the fuel rail to even start, much less run properly. The fuel pump is immersed in fuel inside the gas tank to keep it cool and not burn up. Running the fuel level low causes more heat in the pump and interuptions in proper fuel pressure. AC/Delco pumps have proven to be a reliable fix, the aftermarket pumps only last for a month or two sometimes. Check fuel pressure under the hood and power and ground to fuel pump at electrical harness at top of gas tank. This truck needs a fuel pump.

Daewoo lanos 2001

plugs new?  fuel filter new?  check fuel delivery to a jar.  500ml in ten sec. is good i recon but specs are better from manual, dont burn yourself gas burns quickly. if pump delivers well then the filter needs to be changed or injectors need cleaning. also check air filter and throttle throat for dirt.
