Engine turns over but does not start. I poured

Hi Clyde:
Since you mention "gas rail" I'm assuming fuel injected.
I'd check the fuel pressure in the rail. Should be around 40 PSI.
If pressure is OK then injectors not working. Time to check cps.
You know the spark side is OK since it will run.

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).

Sounds like your not getting fuel. Turn key on and listen by gas tank and see if you hear a buzz sound. if you don't you'll need to replace the fuel pump.

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.)

If the car is getting power from the battery(lights turn on; radio turns on) when you turn the key, then it is your starter or gas distributor. To test that, you need to pour a little gas right in the hole where the engine and intake meet. Pour a little gas in that hole. If it starts up, then it is your gas distributor that is the problem not giving gas to the engine. If it doesn't start up with gas in the engine, then it is your starter. Either will be $100-$200 fix at a shop.

Try pouring some gas in the intake dont go nuts with gas just a few ounces if the vehicle starts and then shuts off you have a bad fuel pump. I have a 1996 Blazer and I replaced mine last year make sure if that is the problem that you shop around for a price because it could save you hundreds of dollars shop around. If it runs and keeps going it could be you fuel injectors are bad. Last winter i had to put gas into my intake when it got real cold. What happens is the fuel gels when it gets cold and it makes it harder for the injectors to take it in . I also replaced my fuel injectors now this winter it starts right up.
( If you dont no where the intake is locate your air filter and follow the intake vent where the vent hose connects to your engine. Unscrew the clamp pull off vent hose and then pour the fuel inside of engine fuel intake manifold. I will bet money your vehicle will start if it dont you have some type of electrical situation.

this sounds like a bad fuelpump, try spraying starting fluid in throtle instead of pouring gas, when you pour gas it may not enter all cylinders it may just sit in intake galley. try the starting fluid.also have someone crank the engine while you beat on bottom of gas tank with a rubber hammer, this sometimes shakes fuelpump and make a contact to get pump going again.

YOUR BEST BET IS TO GO AHEAD AND REPLACE YOUR FUEL INJECTORS. BY POURING GAS IN TO YOUR INTAKE. YOU KNOW ITS GOT TO DO WITH YOUR FUEL SYSTEM. I TAKE IT YOUR CHECKING FURL PRESURE ON THE CHECK VALVE ON THE FUEL RAIL FOR THE INJECTORS. REPLCE THOSE AND YOU SHOULD BE GOOD. JAKE.B

turn the key to acc mode and if the check engine light is on then the computer is working. check for spark. listen for the fuel pump to turn on its in the back passenger side if both those work and you didnt mess with distributor plugs rotor or cap then you may have to bypass it. or the fuel injector could be clogged. take off the metal air intake to get to the fuel injector and pour a little gas directaly in and see if it starts. if fuel pump spark and pouring gas into were the fuel injector is then it might be a bad fuel injector or it needs to be bypassed.

A 1999 GMC Yukon has a fuel-injected engine. They are known for the fuel injector lines inside the intake plenum to break and flood the engine. If you are pouring starter fluid and gas in the intake you are only making it worse. replace the injector assembly with the "new improved" injector assembly and replace the plugs, then it will probably start.
