When you turn the key to the start position does the starter spin the engine ? The engine cranks no start ! Or nothing happens when you the key to start position ? no crank no start ? Is the anti-theft light lit on the instrument cluster (SECURITY) ? If the starter spins the engine does spin slow or normally ? Is there spark , fuel pressure ? Testing these thing's would be the place to start if the engine spins ! Videos on youtube showing how !

Engine acted like it was going to stall, then tachometer(rpm) and speedometer jumped up high, gas gauge dropped to empty level though there was half tank of gas acted like it wasn't getting gas pumped gas...


Ignition or fuel problem probably . When you turn the key to start does the engine spin ? Crank no start or nothing happens NO CRANK - NO START ?
If the engine spins an does not start an run you need to test to see what's missing Spark or fuel . Pull a spark plug wire off a spark plug an stick a screw driver in the end an hold it near ground (metal) and have someone try to start the vehicle ! Is there spark ? Spray starting fluid into the engine , does it start then ?

My 1995 jetta gl wont start


The first step is to check and see whats not working, when you say it wont start then do you mean you turn the key and nothing happens then you may have a bad battery or starter but if the engine spins and spins but wont start then you will need to check a few things. First is to check the timing belt, remove the upper timing belt cover and have someone trun the key and make sure the cam spins and the belt is tight if thats okay then the next thing to do is try sparying starting fluid into throtlebody , have some one hold gas pedal to floor then yoiu spray the starting fluid into throtlebody for about 5 sec, then release gas pedal and then try to start. if the car starts then dies after a few seconds then you will know its a fuel problem. if that doesnt do anything then remove a sparkplug wire and stick screwdriver into the end of the sparkplug wire and place it about 1 inch away from a metal part of engine and then have someone try to start car while you watch and see if the screw driver or wire sparks, this will tell you if its getting spark if theres no spark then you may have a bad control module or bad coil, start with these tests to find out whats the reason for no start.If the battery is good then the engine should spin over and the only thing that may be missing is spark or fuel or the timing belt broke, good luck.

98 malibu,cranks no start,good fuel pressure,good spark,pulled valve cover and rockers are moving,starter seams to spin to freely like there is no compression


may be flooded. hold down gas pedal all the way and crank the engine, after a short time the engine will start to splutter and sound like it will fire. ease the gas pedal off slowly, while cranking, enough to get the engine started it may take a couple of goes. it may blow grey smoke when you get it going this will be raw fuel. holding the gas pedal down all the way, the engine will go into CLEAR FLOOD MODE and the injectors will not deliver any more fuel, until you ease off the pedal. check for dribbling injectors and the shop.

1980 318 dodge truck, engine spins over and doesn't start. I've heard its "the running system" switching from starting to running mode??? I've replaced electic moduel (on firewall), cap,rotor,...


Does that have the ceramic ballast on firewall as well? If so, use a jumper wire from terminal to terminal to see if that helps. (ceramic block about 1-1/2" x 3") usually was located on passenger area firewall behind engine.

Spinning sound when pushing gas peddle, sitting


try it with the belts off you can start it and see if the spinning noise goes away then it's accessory's like bad alternator or power steering pump but dont run it more than a minute or two or it will start to overheat. and if it still makes spinning noise make sure it's not coming from the transmission /use a broomstick against the engine block near each piston to hear the condition of the pistons if there scored real bad it makes noticable diff noise than a diff piston will make. check the front of the engin the water pump sometimes needs to be replaced because the bearing in it drys up and fails / there sealed bearings in a water pump than go make noise . good luck give you stuff to think about.

94 toyota corolla doesnt start


check battery first, if engine spins but no start then check for fuel, also remove a sparkplug wire and spin engine see if there is spark, may be a fuel pump if no gas or a disturbutor or its cap if no spark, if it doesnt spin at all then may be battery or starter, hope this is helpful.

Car won't start


If by "trying to start" you mean that the engine is turning then it isn't the starter that's bad as a couple have said. The starter's sole purpose is to spin the engine so it can start if, gas, spark, compression and timing are correct. If any one of those four are not available the starter can spin the engine until the battery dies and it won't start. If you don't know how to check for proper delivery of fuel, spark, timing and compression then I'd suggest taking it to a reliable mechanic.
