Well there are many things it may be. Start with fuel filter, it may be plugged up and dirty. That's the cheapest and easiest fix. After that fuel pump.

Ran out of gas put some in but wont start. Got gas to return line but none in carburater


You don't have a carburetor, your fuel injected. The fuel goes through the fuel injectors. I'd use a gage and check proper fuel pressure, engine cranking.

My 2000 Isuzu nqr cranks over great but wont start,i'm getting fuel to the filter but not to the injectors


big NQR TRUCK what model NQR 200, 300, what?
. what displacement engine, how many cylinders.?
Diesel right they only had gas in 1995 i think,
so is it direct injection (fuel rail direct?)
there are over 12, model H engines. 4Hxx all 12 are DI direct Inj.
so DI engines, have a ECU that injects. (much like modern gas engines,and huge injector pressure. , compared to port inj.)
so
  1. check fuses first.
  2. scan the PCM yet. ? that is 2nd, and mandatory.
  3. fuel pressure good (tricky on Direct injection read the FSM yet)? Some engines have sensors here to see pressure, scanned
  4. the PCM needs crank signals to inject. and reports them if bad.
  5. the glow plugs work? i check voltage then use my current meter amp clamp tool to be sure all suck spec, current, if not fix that.

post real engine names.
and country

or google, "diagnosing direct injection"

2004 325xi BMW wont start - replace spark plugs and fuel pump


If u hear the engine cranking in the AM, the batt & alt sound good. If you don't get any engine cranking in the am you may have an electrical short draining the battery. Before u convict the starter u must make sure the battery has full power in the AM. (12V) & 12 V to the starter

Car ran out of gas, i put almost 2 gallons into the tank and it wont start. what can i do? and would putting fuel into the carburetor work? where is it located?


Fuel into the carb can lead to a big boom. I would have thought it was fuel injected anyway. If it is fuel injected it can be a pain to get the air out of the system.
In the past I have on the occasion of running out of gas and being stuck with a no start afterwards.....
Take cover off of air filter, usually mounted on passenger or driver side wheel well area (Follow the large tube from the center of the engine until you get to the box). Starting fluid is safer to spray into air tube then try starting.
If in a pinch though, once you can see the air filter pour a small amount of gas onto the air filter itself, close air filter cover and crank it up. The gas vapors will start the car but not put a flamable liquid too near the engine and sensor; you may have to do it a few times as it works the air out of the fuel system.

Engine stalled out,would not start, pour gas in carb,cranks,keeps running,until idle falls below 12to1500rpm,than stalls out again and will not crank,repeat gas or starting fluid in carb,cranks runs and...


This truck is fuel injected, the problem sounds like a weak fuelpump, it runs when you pour gas into it until that gas runs out, the first thing is to test the fuel preasure, if the pump is weak it may run with gas poured into it but wont idle, also a common problem is the coolant temp sensor and the ground wires to thermostat housing bolt but i wont bet its the pump inside the fuel tank, if you put a fuel gauge on it there should be at least 55-61 psi if its a few pounds lower it can cause problems, you have everything else and it runs with gas poured so its a fuel problem check the preasure, theres a valve up top on the fuel line to connect a fuel gauge to it, start there hope this is helpful.

Engine won't start.


Sounds like your fuel injecters are plugged. Wouldn't do you any good to add fuel injecter cleaner to your gas if engine won't run, so you would need to remove your injectors and clean or replace them.

I have a cadallic escadale. It will turn over but wont start.


The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

My s10 will turn over, but wont squirt gas through injecter


Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's
