Crank or cam sensor. Have a OBD II reader plug into it and see if you have any codes.

Won't start


Year make and model. Is the security light staying on/flashing? Pull a spark plug wire and see if it has spark. That could be a coil/s or crank sensor.

1977 jeep cj7 will not start very well and when it does it turns over a little and then shuts down any answers ?? the fuel pump seems to be ok.


If I remember correctly that Jeep had a mechanical fuel pump attached to the engine. I suggest you disconnect the fuel line before the fuel filter and put a pressure gauge on the line. Crank the engine for at least 15 seconds and go see if you have at least 7 lbs of pressure. If not, you need a new pump. It that was good, now disconnect the line AFTER the fuel filter and see if you have a sufficient volume of fuel coming out. For that I suggest you have someone else crank the engine while you hold the hose in a pail. If the stream is weak, change the filter, reconnect the line and see what happens. If it still starts and stalls it could be a clogged carburetor.

Did you do a spark check by holding the plug wire away from the engine while someone cranks it? With a spark plug in the wire, hold it at least 1/2 inch from the engine while someone cranks it. That spark should be able to jump off the plug and into the engine. If not, you have a weak coil. If the spark is strong and you have the correct plugs installed, then it almost has to be the carburetor.

Good luck with that, I have fond memories of older jeeps.

Why my 2005 ba ford falcon wont start?


Its either no spark or no gas. Remove the fuel line and carefully crank it over..are you getting any fuel? If not possibly clogged fuel filter or bad fuel pump. If yes, are the spark plugs firing. Remove number one plug lead hold close to any metal surface on engine, crank over ..spark there..strong or weak spark? No spark check coil and associated parts.

1992 mercury sable will turn over but wont start


Make sure battery has a full charge. If it cranks good but won't start, check the basics. Have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure. I looked at info for the 3.8L engine, 35--40 psi. Also, after you build fuel pressure, turn off the key, see if fuel pressure holds for a bit? If the pressure drops like a rock, check for fuel pressure leak. Check the vac line for fuel pressure regulator, if it has gas in it, the regulator is faulty, or a leaking fuel injector. The pressure could also drain back through fuel pump.
Also, check fuel injector pulse, engine cranking. Any applicable trouble codes?
Smell of the crankcase oil dipstick, if it smells like gas, either you don't change oil and filter very often or the engine is running very rich for some reason.

2003 kia Sedona won't. start


If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.

Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.

The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.

I ran my car out of gas and after putting gas in it still wouldnt start. i got told to change the fuel filter...i did and still wont start even thou it wants to...it trys to turn over but still wont...


You don't pressurize anything
You didn't have to change the filter either

You need to check to see if the fuel pump
comes on at all,in the start position when cranking

If you have fuel pressure at the fuel rail on engine

If not then the fuel pump may have failed

Also, do you have a crank signal, spark,etc

Have it taken to a repair shop

Engine has spark also appears to be fuel pressure but wont start .winds over ok partly fires but wont start .was running ok but just stopped and wont go.all fuses etc appear ok.no engine management light...


Recheck your spark and make sure you are getting spark at each cylinder. Check the fuel pressure by popping off one of the gas line and see how strong the flow is, if you have a weak flow your fuel pump isnt operating properly or you have a clogged fuel filter. Give that a try and let me know if that works if not I will take you to the next step.

Turn key to start-engine turns and i have spark wont start


I would check fuel pressure so you can rule out pump. I had a bad pump right out of the box before. Also you may want to change fuel filter so you can rule out plugged filter. You have spark, sure seems like still no fuel.

Eengine wont start has gas and spark?


Does it sound like its spinning or turning faster than normal? If so could just be flooded. Try cranking engine with excellerator 3/4 way down at 10 sec intervals with 2 min brake in between. These cars have always seemed to flood easy. And the air intake system is so enclosed it cant really dry out easy. I try that 3-4 times if it does seem like its trying to start or getting better than Id say tow to mechanic. Possible coil problems too? But seen alot of them flood out.
