The fuel line is located along the passenger side of the frame, and there is several links/splices, including the fuel filter, located just behind the passenger door. check along those lines. My truck wouldn't start and I had a small leak, when I fixed the leak, it started and ran fine. hope this helps

My car will not turnover and it smells like gas


Define turn over , the engine cranks over but doesn't start ? Turn the key to the start position and it does nothing ?

Are any warning lights lit on the instrument cluster , check engine , service vehicle soon , security etc... Look in the engine compartment , under the vehicle for fuel leakage , turn the key on then off to prime the fuel system an look for leaks on top of the engine , fuel pressure regulator ! If the engine does crank over an doesn't start , passably the spark plugs are fuel soaked - fouled !

96 tahoe . It will not crank up unless I pour gas into the throttle body . Once it cranks it will run untill I shut it off but want crank by itself . Why


First, lets be clear with terms. To crank is to turn the engine over, you can do this manually with a wrench on many vehicles. It requires no spark or air. To turn over or to fire is when you achieve combustion. Example: You could pull the spark plugs on a vehicle and turn the key and it would crank, but it wouldn't fire or turn over.

Now it sounds to me like your vehicle is cranking but not firing unless you pour gas in it. My first thoughts are fuel system. I'm assuming it can't be fuel pump because it runs once it fires. Perhaps the fuel pump isn't priming itself, or perhaps somehow air is getting in the line between the injector and fuel pump? Test the fuel pump first by turning the car from off to on (not starting, just on). You will usually hear a short buzzing noise coming from the engine bay that stops shortly afterwards, that's your fuel pump pressurizing the line. (Pro Tip: If you ever try to take your key from off to straight to start and the vehicle doesn't start on the first try, but does the second time no problem, try delaying at on for a moment before trying to start. This gives your fuel pump time to pressurize the line.) Assuming your fuel pump is charging the line, the next place to look would be at the path the fuel takes to the throttle body. When you crank it over and it doesn't start, are you getting any fuel? If you can't see where the fuel enters the system try smelling the exhaust while cranking without it firing, if it smells of fuel you're good and need to look at air flow and spark, if not it's a fuel issue.

Past that, I'll leave it to someone more experienced than myself, but that would be how I troubleshot my own vehicle.

2002 Ford Explorer ran out of gas put gas in and won't restart. replaced fuel pump and fuel filter still won't start. Cranks but won't start


Most Fords have a fuel reset button. When you ran out of gas you tripped the circuit. Most of the time the button will be on the passenger side by the kick panel. The exact location should be in your owners manual or your local library or auto parts store will have a copy of one for your specific vehicle.

I have 02 pontiac grand am and it wont start, it cranks over and getting spark and getting fuel, I replaced crank sensor, however i pulled spark plugs and didnt smell gas in the cylinders when someone else...


Attempt to start the car by turning the key to the Start/Run Position.
Observe that the vehicle fails to start and that the security light is illuminated. leave the key in the 'ON/Accessory' Position. (DO NOT turn key to the 'off' position.)
Allow the vehicle to sit with the key in the 'ON/Accessory' Position for no less than 12 minutes.
Turn key to off position and allow the vehicle to remain in the 'OFF' position for no less than 30 seconds. Then start the engine. This worked for me.

1988 toyota camry 2.0 turns over but won't start. Car has been driving like a champ and one morning wouldn't start. Turns over fine but won't fire. Tested for spark by removing spark plugs...


Fuel pressure at idle is normally 30-35psi. Start by taking the gas cap off, and putting it back on. That will De-pressurize the fuel system. Also, make sure you have gas in the car. I have seen gauges on these cars read wrong. I hope this helps.

2001 ford taurus with the 3.0 after sitting a few hours when i go to start will crank and crank and crank for what seems like ever, will start easily after that but when i go to start it for the first time...


Its not the oil, increasing temperature will thin out the oil. If it cranks easily but won't start it could be the spark plugs or the spark plug wires. When they heat up, especially if they are old, they won't perform well. Pull off one of the wires and hold it close to the plug, try to crank the engine and look for a spark. If it sparks them try removing a plug and check to see if it looks wet. If its bone dry it might not be getting fuel.

Car wont start


Hi,
If the engine cranks over normally when you attempt to start you car, but the engine does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION. The engine needs adequate fuel pressure, a properly timed spark and normal compression to start.


1) To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. If it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.

2)Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.

3)Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine..


Thank you !!

Fuel problem


wouldn't be that.. if you smell fuel, your getting fuel... prolly a spark issue, pull off a wire and CAREFULLY turn engine over and look to see if spark is arching.. if so, plugs are prolly fouled, remove, clean and or replace...
