Very High Probability that the injectors are colgged. When a fuel injected motor is non operational for more than six months, The trapped fuel at the tips of injectors will turn to varnish (just like a caburreted engine) thus clogging injectors. No fuel can get through the injectors thus no start situation.

To test this theory, get a can of starter fluid (as well as a fire extenguisher handy) have an assistant spray some into the intake throat while attempting to start engine. If engine fires then BINGO!!

Solution 1 Professionally clean injectors which may or may not fully work.

Solution 2 Replace with new injectors.

Need to know why won't get no spark...changed ignition module, ignition coil, cap and rotor still not firing. ....any ideas


What make vehicle ? year an model too ! Before you replaced those parts did you check for battery supply voltage an check the ground for those components ? You need to get a wiring diagram an see what get's voltage an what is ground ! An see what all is involved , crankshaft position sensor , ECM / PCM -engine computer etc...! Then you need a DVOM - digital volt ohm meter to test ! Your looking for a quick fix an doesn't work like that !

Engine turn over wont start


Assume you have gas. BMW does not like to start or run if the battery voltage gets too low (for example sitting in the driveway unused. It does not take long with all the electrical drain(computer, security, etc.). A peculiar item about M cars is if the oil gets 3 quarts low, the engine wont start to protect the engine. Other less common camshaft sensor, crankshaft sensor, ignition coil pack, fuel filter, fuel pump. If it does not crank but battery is fine, check the starter. Turn the ignition to ON but not START then if you cannot hear the fuel pump humming, the fuel pump itself or a relay to it is probably bad. Using a rubber mallet, give a couple of sharp blows to the underside of the fuel tank and then try to start. If it starts, fuel pump is bad. Fuel pump is located under the back seat on the passenger side-easy to get to.

It turns but it wont start,it has gas and power


Pull off the coil ignition cable at the distributor and check for spark coming out of coil when cranking engine over. Use a heavy rag or glove to hold the wire 1/4 inch from a metal ground. Should see a strong blue spark when cranking to verify ignition is good. If no spark, check for battery voltage to coil on the coil primary. If you have current to the coil, suspect a bad coil, ignition module, crank position sensor, or cam position sensor, or pcm. The coil, ignition module, and sensors can be tested before replacing.

Wheres the inhibitor shiwth on a 2001 buick centry


if the car cranks it is not a starter or a battery problem. A car needs 3 things it start . gas ,air ,and spark. do you hear the fuel pump turn on when you turn the key to the start position. car you have some one spray starter fluid in the throttle body to see if you have spark..if you do not hear the fuel pump then that is the problem. if you have no spark. then you need to check a few things. crank position sensor,cam position sensor, ignition coil,

Gets gas gets spark but don't start. new fuel


1. does it turn over? if so, strong, or weak? 2. did you replace the fuel filter? 3. coil packs, or distributor (pack(s) can be tested) if distributed check cap and rotor, replace coil, but first check starter relay - 4. Check all ignition fuses, starter fuse - (along with relay{above}) 5. Check all connections from battery - positive, negative etc.
Please let me know if you need further assistance.

Wont start it cranks but nothing happens.wont turn over. put a new what you would call distributor. still nothing.


If the Starter isn't turning the engine over, but you hear a clicking sound, you may have a bad Starter.
If the Starter is turning the engine over, but you are getting no Spark, you may have a failed Camshaft or Crankshaft Position Sensor, or your Timing Belt may have jumped or broken(common on the neons).
If the Starter is turning the engine over, but you are getting Spark, you may have a failed fuel pump, fuel pump relay, or fuel pressure regulator.

Before you start replacing sensor, double check the Timing belt to ensure it hasn't broken or jumped, and check to see if you are getting a spark or not.

91 volvo 240 won't start after long trips/multiple short trips


If you mean that when you try and start it the engine actually turns over but does not start, then check out the following info (I had a similar problem on my 1989 Volvo 240. It would start fine sometimes, other times it would not start even though it would crank) . It turned out to be the fuel pump relay. 
When you try starting your car and you can not hear the fuel pump turned on (sound coming from the left underside of the car in front of the left rear tire), do the following if you think this is your issue (no cost for trouble shooting and takes 10 minutes to do):
The fuel pump relay is behind the access panel under the glove box. The panel is easy to remove - just unscrew each of the 5 panel knobs/fasteners a quarter turn and the panel comes out/down.  The fuel pump relay is a white plastic cartridge with a wire harness going to it. Just unclip it from the metal clip that retains it and leave it hanging there. When the car doesn't start and just cranks, lean over and tap the relay while you are trying to start the car (tapping it shakes the contacts inside that would normally switch over to complete the circuit when it is energized). If this is your issue and you can repeat the solution by tapping the relay when starting the car, buy a new one (I got mine at www.ipdusa.com for around $14) and kept the old one in the trunk just in case.
Hope this helps.

My s10 will turn over, but wont squirt gas through injecter


Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's
