The mechanic should check on the fuel pump and the Idle of the fuel pump . if the fuel pump is malfunctioning then you have to repair it.Then also the throttle if the throttle is being worn out or malfunctioning then you have to repair or replace it.The Idle should be adjusted because of the engine is stumbling .the reason why the engine is stumbling or the car over heats is that the fuel pump is not functioning good or there is a problem in the fuel pump.and also it is the reason why the engine light goes off when cold because of the engine problem is in the fuel pump.such fuel or is not entering or going to the engine.

How do I know if my fuel pump is gone


Here is a quick test: Turn the keys so that the car is "on" but don't turn it that the engine crank. You should be able to hear a "buzzing" sound coming from the fuel tank for a few seconds each time you turn the keys to ON. The sound you hear is the fuel pump priming the engine.
If you don't hear any sound at all, it is an indication the fuel pump is not running. Check the fuse before changing out the pump.

Another indication is if you start and the car seems to start but then engine stalls. Even if you apply the gas, the engine still stalls, this indicate lack of fuel coming in due to fuel pump not working.

Starting Problem # 1: Engine Won't Crank At All

Scenario: You turn the key, but nothing happens: And by nothing, we mean there is no dash light, no sound, nada. The first thing you should do in this case is to pop the hood and check the battery. Either the battery is completely dead or there's a wiring problem in the starting system. Try jump-starting the battery. If that doesn't work, you'll probably have to call for assistance.

Scenario: When you turn the key, you hear a rapid clicking sound, and the dash lights dim. This is your classic low-battery symptom. Jump-starting the battery should get the engine to start.However, if you keep experiencing this problem, you could have a bad battery or alternator, or it could be some­thing as simple as a loose alternator belt. Take your car to a mechanic just as soon as you can.

Scenario: When you turn the key, the lights on the dash come on, but you don't hear anything. Make sure you have the shift selector all the way in park. Move it out of park and then back, or try starting it with the shifter in neutral. If your car has a manual transmission, make sure you have the clutch pressed all the way to the floor. If that doesn't help, you can try jump-starting the battery, but it probably won't work. There's a good chance your car has a bad starter or a problem in the starting circuit. That could mean a prob­lem in the ignition switch, neutral safety switch or starter sole­noid.

Scenario: The dash lights come on when you turn the key, and then go right out, and the engine doesn't crank when you turn the key to start, But, the lights slowly come back on when you release the key. This is another classic: the bad battery connection. When you turn the key to start, the starter pulls so much current that it breaks the connection. Then, when you release the key, the connection slowly comes back. The connection provides enough power to turn the dash lights on, but not enough to crank the starter. Cleaning and tightening the battery terminals may fix this prob­lem.

Scenario: When you turn the key, you hear a single, hard clunk. Turn the headlights on and try again. Do the lights dim slightly when you turn the key? If so, you probably have a bad starter or a seized engine. If the headlights don't dim at all, or just barely dim, there may be a connection problem between the starter solenoid and the starter itself.

Scenario: When you turn the key, you hear a loud, scraping or grinding sound like metal on metal. The starter drive is bad, or the ring gear on the flywheel damaged, or both. You may get the starter to engage if you try turning the key a couple of times, but let go of the key right away if you hear the noise again. If the car does start, you should drive it right over to local repair shop and have the problem fixed.

Starting Problem #2: Engine Cranks but It Won't Start

Scenario: The engine seems to crank normally, but the engine doesn't even sound as if it's trying to start. Is there gas in the tank? Gas gauges are notoriously inaccurate. If you have to move your head to one side to get the needle to move off empty, try adding some gas to the tank.

Scenario: When you first turn the key on, you don't hear the fuel pump run. In cars with electronic fuel injection, you should hear a light hum a few seconds from around the fuel tank. That's the electric fuel pump running. If you don't hear the fuel pump run for a couple seconds when you first turn the key on, try cranking the engine until the oil light goes out. That may start the pump running and allow the engine to start.

Scenario: The engine cranks normally, and it sounds like it wants to start, but it won't. You may have flooded the engine. Hold the gas floor and try again. (Let the gas pedal up when it finally starts). If it's raining out, the ignition system may be wet.

Scenario: The engine cranks unevenly in a repetitive-sounding pattern. You may have a bad timing chain or timing belt. Call a tow truck and have it towed to the repair shop.


Starting Problem # 3: Engine Starts but It Shuts Off

Scenario: The engine starts right up, but shuts off as soon as you release the key. This is the classic symptom of a bad ignition switch. A new switch should fix it.

Scenario: The engine starts and runs, but when you put the transmission in gear, the car lurches and the engine shuts off. The converter clutch in the transmission torque converter probably is engaging when it shouldn't. On some cars, you can bypass this by disconnecting the torque converter clutch solenoid; but unless you know which wire to pull, forget about it. Call for assistance.

Scenario: The engine starts and runs, but seems to idle slowly and stalls when you come to a stop. This probably is a fast idle problem. When the engine is cold, it's supposed to idle a little faster than normal to keep the engine running. You may be able to drive using two feet until the engine warms up: one on the gas to hold the idle up a little and the other for the brake. However, don't keep driving it this way. Take your car to your repair shop just as soon as you

2000 Eclipse GT turns over but doesn't start. Fires once in a while but won't run. Had timing belt replaced.


Hi, if the car turn over, and it don't start. Then it is like the engine don't get fuel. Or bad a spark plugs. Most common problem is the fuel pump going bad.

It could also be a bad fuse, but a easy way to check if the fuel pump is ok is to have someone stand at the back of the car when you turn the ignition. The fuel pump should make a buzzing sound for a few seconds. And if you don't start the car right away the fuel pump will stop.

If you don't hear any buzzing from the fuel pump/fuel tank then you have a bad fuel pump............

Can you tell me where the crankshaft sensor is located? Would this being bad make it not start sometimes? Sometimes it will start up, other times, not. Sounds like the fuel pump is not running when it...


the crank sensor is behind the crank pulley and must pull off the pulley to gain access to it and it must have the air gap set so the timing slots don`t hit it when the motor is running,this can cause your problem also if the wires rub through by the crank pulley can cause it as well.you say you don`t hear the fuel pump running when it won`t start then you need to make sure that is what is happening as this will cause an intermittent no start(pump works sometimes).do you get a 2 second run pump prime when the key is turned on and a no start then it could be the crank sensor as the computer looks for a crank signal from the crank sensor when trying to start the car.

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.

I have a 2001 Camaro V6 3.8L that stalled on the highway a few days ago. The car stalls almost instantly after starting, ive actually got it to run for about 20 secs a few times but still stalls. Plugs...


When you turn the ignition to on you should here the fuel pump run. If you aren't hearing it then it sure sounds like the pump. Assuming nothing has happened to the car to affect electrical connections. I don't think there is a fuse for the pump but worth checking also.
