Here are two possible options, One you should check on the flywheel and make sure there is a tiny block of metal alongthe rim of it generally on the top but it does move, this is the Crank Sensor Pin and if it doesnt have that then theres no way its going to start, Second, you might need to replace the Speed reference sensor, Its the grey sensor on top of the block, because those combined with the crank pin wont let it start, another one you might want to check even though you say it cranks, is check the Ignition coil

If you have any questions email me, and I can try to help (Had these same problems with more.) The.Squall1@gmail.com

I have a 2002 Chrysler town and country. I have replaced the fuel pump, fuel filter, coil pack, plugs and wires but still won't start. any ideas on what to check next?


I saw what you replaced. What testing have done? Generally, if it cranks good but won't start, have a helper crank it while you check for spark at the plugs, if spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. If your missing everything, I'd check for rpm signal. A lot of Chrysler makes and models, the computer has to see proper signal from cam and crank sensors or it won't ground the asd relay. The asd relay supplies voltage to several systems, including ignition coil and fuel injectors. Engine cranking, do you have primary voltage to those two components? Use a test light. Any applicable trouble codes?

2003 chevy silverado 5.3 will crank but not start and has no power to the pcm1 fuse


What make vehicle ? You need to find a power distribution chart an see where that fuse gets it power . Some vehicles have a relay that powers up the vehicle . ford has power hold relay , gm on some models has a run / crank relay , Chrysler has ASD - auto shut down relay , Asian vehicles have a main relay etc... But as long as there is no power to the PCM it's not going to start !

EF ford on gas cranks but will not fire have changed coil pack and have power to the main loom (plug) to coil pack


Check crank position sensor or cam position sensor if applicable. Is it actually sparking? If so either its not being told when to fire or there is something else telling it there's no fuel etc. Check the relay box for fuel relay etc.

05 c240 turns over won't start


most likely you have a bad crank sensor or fuel problem you need to check fuel pressure ,if you have enough pressure ,most likely you need crank position sensor,if you don`t have fuel pressure ,it might be your fuel pump relay or the pump, i would start with the relay first very unexpensive. you can also hear the pump if it`s working by cranking the engine and listening rear of the car for a humming sound .
good luck

Where is the main relay in 02 dodge neon


I didn't see main relay listed? If it cranks good but won't start, I consider the asd relay, important, under hood fuse box.
You can check the basics when problem is ongoing. If it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
Ask your friend, "what does that relay control?"

Engine cranks over but no fuel being pumped plus no power to fuel pump. No spark to the spark plug. I put new crank positioning sensor, new cam sensor, changed computer, checked fuel pump relays. Car...


Did you check your coil pac? This supplys power to all parts of your auto. I would check and see if your getting fire comming from your coil , Good luck to you.

1995 CRYSLER LHS,WONT START AT ALL,TRIED CHANGING SENSORS,FEUL PUMP,COIL PACKS AND COMPUTER BOXES,JUST WONT START?ANY IDEA?


If it is cranking with out turning over I would check the fuel pump and ignition relay, crank and cam sensors.
Basically you need to figure out if you have a spark issue or a fuel issue. (as long as you didn't have a serious overheating problem). One way to help you figure this out is by spraying in some starting fluid while cranking the engine. If it starts you have a fuel problem, if nothing then you have a spark problem (assuming you didn't blow the head gasket from overheating and was running normally before this happened).
Based on what you've already done here are my recommendations:
No spark: check ignition relay
No fuel: check fuel pump relay (aka shutoff relay, aka fuel pump shutoff relay), crank and cam position sensors, fuel filter.
There is also one other possibility, that the timing belt snapped. You would need to remove the timing cover to check this.

93 honda del sol will turn over but wont start. It has a new time belt, distrib, and the main relay works.


Is it not getting spark or gas? It needs both to run. Both main source. If no spark in any cylinder, then ignition module or crank sensor is likely faulty. If no gas, then fuel pressure regulator or fuel pump or fuel pump relay is bad.

Got s,reg nissan mirca turns over but wont start never had prob before any ideas what might be wrong batt fine ,spark good


fuel pump, fuel pump relay or fuse, or crank sensor.

the crank sensor is located near or behind the main bottom pulley on the front of the engine. it is a very likely problem and is usually an easy replacement, but the fuel pump and its fuse & relay could be the next most likely problem.
