Look along the fuel line its not uncommon to find fuel shut off valve that has been added by a previous owner as part of some fancy alarm system .??if you have fuel to injector under pressure then you have the factory immobilissor cut in

Truck will start but will not idle or take gas when you put it in gear


Sounds like either the Mass Air Flow Sensor could be dirty or defective OR a simple vacuum leak.
To check for a vacuum leak, get a can or injector cleaner or even WD40, and spray around the intake until you hear a change.
To clean the MAF sensor, BE SURE to get sensor cleaner NOT carb. cleaner!!
Or, you can take it to Auto Zone and have the "Codes" checked FREE.
Hope that helps. :-)

Fuel injectors need cleaning


If your injectors are dirty , it could get less gas on takeoff so i\'d say it could help but definetly, you got to have it professionnally done and not only what you can buy at canadiantire and put in your tank. I would suggest TeraClean injector cleanning or something like it.



You need to be sure to not only clean injectors but to change your fuel filter to cause if dirt can go to you injector rail, you can be sure it comes from a clogged or no good fuel filter .

Diesel not getting to injectors


r u sure that fuel is not gettin to the inj? what motor what car, it could be a HPOP (high pressure oil pump) that is what opens the injectors on some applications could have leak in the fuel system and its sucking air instead of fuel filter clogged with gel or bacteria, and r u sure you put diesel in it and not gas by honest mistake?

We replaced fuel pump in 1998 camry and it still wont start power is running to and from injectors and pump.


unhook the fuel line to the filter and check if gas is coming through....i just recently had to replace the fuel pump in a costomers car 4times because the other ones i was gettin were bad and yes i was buying them brand new...and if your not getting gas take the fuel pump back out and check the fire to the wire that connects to the fuel pump on the inside because they r lead wires and break very easy...

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.
