The new 2010 Fusion has what Ford calls, "one touch" start. If you turn the key to the start position and let go, the starter continues to turn. The ECM takes over the starting process and monitors the number of times the crankshaft rotates as it adds fuel and ignition for the engine to start. On 2010 Fusion's built before August 2009, there is a problem with the starting process. On occasion, the starter will turn the engine, but the engine will not start. The starter will not time out and the only way to stop the starter is to turn the key to the "off" position. TSB 09-19-1 is supposed to take care of the issue by replacing the ground cable with one that has a capacitor in it. Fusion owners with the no-start/intermittent start issue can go to their dealers with the TSB. I have tried to write down some simple tips that may help you to find out why your car won't start. These tips may also prevent you from being overcharged by dishonest mechanics - you will often be charged more at a garage if you look unfamiliar with the car mechanical aspects.
It's frustrating when your car won't start - this happened at least once to most of the drivers. I had situations when my car won't start many times. But no need to panic. The process that goes on since the moment you took the keys out of your pocket to the point where the engine is running is a fairly simple one and it involves few steps.


The engine computer uses the signals from the crankshaft and camshaft position sensors to know which cylinder is in the compression cycle. If either of the sensors is bad, the car won't start. Similarly, if the timing belt, chain or gears are broken, the camshaft won't turn and the engine won't start

The fuel pump starts running, building up the fuel pressure in the fuel injector rail. The engine computer alternatively opens electronic fuel injectors that spray short bursts of gasoline vapors into the intake manifold (or in case of the direct injection, straight into the cylinders). If the fuel pump is bad, the car won't start.

Ricks63toy, I believe that Ford still uses what is called an inertia switch even in the hybrids. This switch will shut off in the event of an accident shutting off the fuel pump. This is a safety feature built into the vehicle. Seeing that this is a newer vehicle I trust that you still have the manual. If not, the switches are usually located in the trunk. Look on the side walls of the trunk and see if you can locate it. It is usually marked by a sticker. When you find the switch, push the red button down until you hear a click. This will reset the switch and allow power back to your fuel pump. Good luck with this.

Escort won't start when cold and has the strangest solution...


no, not likely. And a dry hose is a good sign, but a hose wet with gas is a sure sign of a failed pressure regulator. Your problem may be the pump not priming the fuel system. Here's how it is supposed to work: when you turn the key to on, computer will signal the fuel pump relay to turn on for about two seconds, and without a cranking signal from the engine, computer will then turn the pump off. When key is turned to crank, the computer will then turn pump back on-when engine is cranking or running, the pump is on continuously. But just turning the key to on, you should hear the pump run for about two seconds, and that will pressurize the fuel system.
At those times when it doesn't want to start, you should test the fuel pressure to see if the fuel rail is pressurized. If no pressure or low pressure, diagnose the wiring at the fuel pump relay. The relay is very simple- 4 prongs, 2 on the power side, and 2 on the coil side. The power side has a hot at all times wire and then the wire going to the pump. The coil side of the relay has a wire from the engine computer, and the other coil side wire is a ground. When the coil side is energtized by the wire from the computer, the relay is switched on and will pass power from the hot wire to the pump. So if the pump doesn't come on briefly to prime the system, the computer may not be signalling the relay, or there is a wiring problem around the relay. Good luck. You might just try a different relay-maybe yours is sticky and not responding.

Why won't the fuel pump shut off


Fuel pump won't be the cause. Most likely the relay.

Won,t start after sitting for a short time, but will start fine when cold


Does it crank, yet not start? Or does it not even crank?
If it cranks and doesn't start, you could have a leaky fuel injector. Pull the plugs when this happens, and check them for fuel saturation.

If it doesn't even crank, it could be an intermittent starter.

Car won't stay running after sits overnight and runs good after you do get it started


In the morning, turn key to on position for 5 seconds. Do not crank.Then turn off for 5 seconds. Repeat this about 5 times. Then try to start. If engine starts right up, the fuel pump check valve is bad. Meaning all fuel in fuel line is returning to the tank when car sits overnight. The only fix is to replace fuel pump. If that doesn't work, replace coolant temp. sensor for the computer. About a 12.00 part.

It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

How do you test the fuel pump relay on a 1991 Toyota Celica 1.6 Car just died and won't crank. We changed the ignition coil and still won't crank. Fuel pump is working. Toyota place does not check...


If the car will not crank then you have a battery, cable or starter issue. If the car will crank but not start then the problem may be the fuel pump relay. There should be an electrical diagram on the side of the relay. Apply 12v to either side of the coil and you should here a click. Then check for continuity between the other two terminals with voltage applied. If you have no continuity then the relay is bad.

I Have a 2006 pontiac G6 gt with the 3500 engine, The battery was removed positive side first and now after it was replaced the fuel pump isn't working, everything else seems fine but the pump...


You can't fix it yourself. It takes a scanner at your Local Dealership to do it. People do it, (new battery) everyday unaware that doing so can and usually does, arm the theft system and either kills the radio or the whole car. To me it's just another built-in defect that requires dealer assistance. It's a buzzkill I know, and it probably won't be long until car owners won't even have access to the engine compartment. Sorry.

98 Chevy blazer won't start up but will crank ,,


Try giving it a shot of starting fluid. You don't say if it's actually firing. If it tries or runs for a few seconds off of the starting fluid then try changing the fuel pump relay. It's inside of the glove box on the left hand side behind the little door. If that doesn't work it's most likely the fuel pump.

I have a 96 pontiac grand am that doesnt start all the time


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

It won't die when pulling the relay because it has another power path to the fuel pump through the oil pressure switch .

Plus when it won't start ,don't guess or theorize ! Test what's missing ? check for spark , no spark check ignition system , coil's , ignition module , crank sensor etc... has spark ,do a fuel pressure test etc... don't think computer , when it won't start does the check engine light come on with the key on run not start . If light is lit ,nothing wrong with the cumputer . If want to fix cars you really should take some automotive classes . Test don't guess .Watch some other videos crank no start videos etc...
