It is very unlikely that all injectors are plugged. It would be either the ECU not letting the injectors open, or I would also check the valve on the fuel rail. Sometimes it is electric and sometimes vacuum. If this malfunctions you will have plenty of fuel pressure but nothing will get to the injectors. Hope this helps!

Engine wont idle


Change the air filter if needed, clean the mass air flow sensor and the throttle body with brake clean. Spray the MAF, use a toothbrush on the inside of the throttle body especially around where the throttle plate sits.

1987 jeep comanche will stay runnning only when spraying carburetor cleaner in carburetor or when you pump throttle rapidly


Hello
It sounds like a glogged fuel filter or throttle body problem. Disconnect gas line at carb get a small jar or can to catch gas, hold gas line in jar and have someone crank engine, If you have good gas flow to carb then Its a throtle body problem, (Throtle body and carb are same thing just in case you did not know)could be electrical or mechanical problem at throttle body, Its usually electrical, fuel flow meter. Hope this helps

My truck sat up for probably 3 or 4 years cranked and run fine yesterday but today it wont crank at all any ideas?


If it won't crank over, it's not a fuel issue, but a starting circuit issue. The gas may be stale, but if tank was full all that time, I don't think that would be a problem.
Pull off the small wire on the starter solenoid, and see if it has power when key is held in crank position. If power there, the starter or solenoid or the battery connections from battery to starter need to be checked or tested. If no power to solenoid when key is in cranking position, the ignition switch may be bad or the neutral safety switch (or the clutch start switch if a manual) or the starter relay needs to be checked.
If you get it cranking, and still no start, look down the throttle body bore and watch your injector spray pattern while the engine is cranking-you should see a fine, cone spray pattern coming from the bottom of the injector. If it just drips and no cone pattern, or no gas coming out, injectors need cleaning (probably from stale gas). Good luck.

How to clean throttle body on 07 envoy?


To clean the throttle body you will need a tooth brush and some throttle body cleaner spray.Remove intake hose on throttle body, you may have to also remove the air cleaner but most times you can just move it aside.
This being drive by wire you will not be able to open the throttle by stepping on the gas pedal. you will need to use your finger to push it open,Push throttle plate open and spray plate and body, then use toth brush to clean plate and body. spray to clean out and use brush to loosen carbon. place a rag under the throttle to caught cleaner run out, the rest will burn in engine.
After you clean start truck, if truck is hard to start then step on pedal to start, this will clear out the cleaner. try not to over do it on the spraying.When cleaning you want to clean area that plate sits against. For example the closed plate, the area around the plate is the area that air is sucked through and with carbon build up there it restricts air flow at idle . thats the area to clean, the plate edge and body. hope this is helpful good day

1989 pontiac firebird idles eracticly and


Try spraying the idle air passage in the throttle body with a carbuator cleaner while the engine is running, you will have to hold the throttle to keep the engine from dieing.If that helps a little than you may have to remove the idle control valve from the throttle body and try cleaning it out with a carburator spray cleaner and also spray clean the idle passge in the throttle body.Or you may have to replace it,
The idle vale should be on the left side on the side of the throttle body -- passenger side --- with two torx head screws holding it down. It has a three wire quick connect plug that looks like a race-track--- rectangular/oval.
Good Luck.

2005 MPV shuts off after I let go of the gas after


I'd pull the "idle air control valve " (located on side of throttle body near front) off, and use some throttle body spray cleaner on it & the port it came out of. Spray pintle (pointed part) good to remove any gunk etc. Re-install, it & try it. if it cures your problem for a while & starts to act up again, replace it.
