Have your fuel pressure check it should be 58-60psi with the key turned on.The truck will run on 50 psi but will not start the truck.So if you get it started by spraying the intake and it still runs then the pressure is not high enough to start the truck but high enough to run the truck

Is it a carb problem if I have to spray ether in carb for car to fire. Doesn't always stay running if I do. Carb or fuel line?


Probably fuel pressure issue. Check for leaks, dirty filter, low fuel pressure could indicate bad fuel pump. Normally, a float would cause flooding, but a clogged jet could cause a lean / no start issue. Try some gumout fuel cleaner and a gumout spray clean of the carb and linkages before you get to far into a part issue.

1995 Tahoe will not start till i spay carb cleaner then will run fine


Is the vehicle diesel? If so you have a heater plug problem, or low compression, compressed air in the cylinder is not hot enough to cause ignition of the diesel in a cold start situation. Carb cleaner is more volatile than diesel and explodes easier, so the vehicle starts. Heat retained by the engine allows it to start, then when it has gone completely cold, you have the same problem, Check operation of the glow plugs and the engine compression (worn engine)

Won't start in Cold weather in Warm Weather it's fine


without actually hooking up a scan tool and looking at the pid data i would say you have either a coolant temp sensor issue or intake air temp sensor issue.i have seen alot more coolant temp sensors bad than the intake air temp sensors tho.

STARTS BUT WONT STAY ON WITHOUT KEEPING MY FOOT ON THE GAS AS SOON AS I LET THE PEDAL GO IT SHUTS OFF


try this.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

The motor start only with carb cleaner shot in air


What year is it?
4 cyc or V6?
====
I will assume you has a fresh tank of gas.
Here's a lot of to do / to check list.

clean air filter
clear air passage intake tube
clean mass air sensor MAS with electronic part cleaner
clean carb. or throttle body with carb. cleaner.
check or replace spark plug/wires/cap/rotor
check timing
change coolant (it's over due)
oil change (it's over due)
fuel filter (it's over due)

Give it a little TLC and it me know
