Is fuel pump real loud? See if fiter is clogged> If not see if injectors are spraying. See if there is electric power at the injectors. Spray starting fluid {not alot} inthe throttle bank, this will tell if you have fuel problem.

2002 Saturn Vue died on freeway, colse to starting, just won't go.


There is no close to start ,something is missing spark or fuel pressure . If it died on the freeway the fuel pump quit working or something in the ignition system did . The engine spins when you turn the key to the start position ? Crank - no start No Start Diagnostic Basics EricTheCarGuy

Why wont my BMW 93 525 I wont start turn over but will not start


When you turn the key to the on position do you hear a buzz from the rear of the car for several seconds? If not possible bad fuel pump or relay or fuse. If you get the sound check the ignition coil for spark. Pull the coil wire and have someone crank the engine for you Observe if there is spark going to ground. You first need to know which system has failed.

Saturn sl2 turns over but no fire. it has spark. what else could cause this?


Go out and turn the key to the on position and see if you hear a whine coming from around the gas tank which is the fuel pump priming the fuel system. You should be able to hear it from your seat, but if not, have somebody get down and look under the car to see if they hear it. If you don't hear anything, then it is most likely a fuel pump or possibly the fuel pump relay. Everytime I have not heard a noise, though it was not the relay.

Hope that helps.

2003 gmc savanna, wont start, new fuel pump and ignition cylinder, I turned key to on position, let sit for 15 min and still wont start just turns over


Find fuel test valve in fuel rail on top of engine. Take cap off valve. Turn key on. Push down valve with screw driver. fuel should squirt out. If not check fuse fuel pressure relay and bad wires. If fuel does come out, remove a spark plug from engine. Connect plug wire to plug. Ground plug against engine. Crank over engine and look for spark.

2004 grand am stuttered then stopped working all together, wont start at all


Fuel pump? When you turn key to ON, do you hear the pump come on for 2 seconds to pressurize the lines? If not, you will need to have the fuel pump circuit checked for a failed fuel pump.

If the pump is working, start looking into the ignition system by checking for spark on one of the spark plug wires. If no spark, possibly the ignition control module or the crank position sensor.

I have a 93 s10blazer 4.3 vortec 4x4 that wont start. my fuel pump is working i replaced the ignition module, ignition coil, plugs n wires r good, distributor cap and rotar button. idk what it could be


First spray starting fluid in the air filter. If it starts it is a fuel problem. If it doesn't start then pull one of the spark plugs and see if there is spark. If there is not spark then it is an ignition problem.
If it is a fuel problem and the fuel pump is running when you turn the key on, then check fuel pressure. It should be over 35psi.
If it an ignition problem start by checking fire at coil.

My car runs great, but when i turn it off and try to drive it again in a minutes it wont start .i have to let it set for a while before it will start again


crank position sensor, camshaft position sensor or an injector with too many ohms resistance. when you turn the key to the on position you should hear the fuel pump come on for a few seconds. if not suspect fuel pump relay or fuel pump

you will need to determine if it's a no spark issue or a no fuel issue.

When the car wont start spray some carb cleaner or starter fluid into the intake and try to start. if it does start and run for a few second then the problem is with the ignition side

check for spark by removing a spark plug lead from a spark plug and putting a good spark plug in the wire, use a jumper cable and clamp one end to the spark pug thread and the other to battery ground. Turn the engine over and you should see spark.

is the check engine light on? if so get the computer scanned, autozone will do it for free

My 93 saturn sl turns over but wount start


what needs to be checked is spark and fuel. spark is easy, pull a plug and see if it arcs while cranking. if that doesnt happen i would start at the plug and work backwards.

as far as fuel goes first i would check to see if the pump turns on when turning the key in the on position (not cranking) and listen for a humming. if that is heard i would move to the fuel rail and check for fuel pressure by pressing in the valve on the driver side of fuel rail (usually covered by a cap, looks like a large tire valve)
