Well first thing is it does not have a carburator, it has a throttlebody. and the fuel pressure needs to be atleast 45psi continous, and a couple pounds less while cranking. first thing to check would be fuel, then spark. if both are present, then do the pressure check. could have helped with more info.

Fuel in filter and start pouring gas in carb, but won't stay running


Make and Model, year of vehicle?
I'm assuming the vehicle won't run unless you pour gas into the intake. If the vehicle will start and run while manually feeding gas to the engine, you can rule out spark and timing issues. Usual suspects in fuel system are dead fuel pump (electrical or mechanical?) clogged delivery system ( fuel line, filter, injector or jet) or intake leak (bad gasket or seal, vacuum leak, stuck valve). 25310438-za4bqvjhdrn3arnyccyp5xaz-5-0.jpg

Car will not run unless gas in carb


Sounds like the fuel pump is bad. The engine is just not getting fuel unless you pour it in the carb.

My Chevy 2500 p/u will only start and run when I pour gas in the carb...if I kill it for 2 minutes , I have to do it again to get it started ...uhg..frustrating !!! One guy told me it was a spider sumthing...


Lets start with terminology. I am assuming the truck is newer than 1987 so you would have fuel injection. No carb.
If it is a vortec engine, either a 4.3 or larger, and built after 1993, it could have central port fuel injection. That style uses one injector and a spider of lines that go to each intake port. This is inside the upper intake manifold.
Vortec engines require more fuel pressure than engines with port fuel injection or throttle body injection. So the first thing you need to do is check base fuel pressure before and after you crank the engine. You'll need a pressure gauge to do it. Normal fuel pressure at idle for a port injected engine is 35psi and 60psi for a central pfi system.

93 geo tracker will turn over but wont start unless you pour gas in intake then will continue to run until you kill it. will not start back unless you pour more gas in intake.


Sounds like something is letting the fuel pressure bleed off after the motor is turned off. Can you monitor the pressure? (Requires adapters and gauge.) Trouble shooting will be a little different between the 8 valve or 16 valve motors. (The fuel injecton systems are different.) You might want to go to a Suzuki Forum. (Your Tracker is a rebadged Suzuki.)

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.

1992 chevy astro van getting fire but not fuel stalled while driving replaced fuel pump when we pour gas into the intake the engine will fire but not getting gas


Did you change the filter? Can you hear the pump cut in for a few seconds when you first turn the key the "run" position? If you can'r hear it, you may want to check fuses and power wires to the pump.
