Theft light on? Flashing? Also, if you can't afford to rent a scan tool, how do you plan to get the trouble codes? It's like asking a Dr. to diagnose you but refusing to get lab tests. If you want to fix it yourself you need the proper tools.

SOURCE: 2002 Kia Sportage will not start.

p0560 is system voltage problem. open or short between the battery positive and the ecm.CHECK ALL FUSES. dosnt matter what they are labeled under dash and under hood replace any that are bad and retry to start. no start then check voltage to ecm grounds to. i dont have a wireing diagram to give you but for a small fee or free the dealer can make you a copy.make sure all the wires that go to battery terminals are not corroded and are making good contact [verified with volt meter]. if after all checks ok then replace ecm. as a side note i havent had to change one ever.

Testimonial: "Thank you for the help. We will continue to check all fuses and wires."

SOURCE: have a ford explorer 2005 xlt having problem

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.


Have you hooked a scanner to the computer and checked the oxygen sensor(s)? If they are bad they could lean out the engine. The MAF Sensor can cause starting issues. Check the filter side of the MAF Sensor for any debris. I have found feathers, leaves, rags, etc. in them.

Remember an engine needs three things to work properly...Air / Fuel / Ignition(Spark)

SOURCE: PASSAT WONT START ALL THE TIME. NO CODES

sounds like a Crank Position sensor. It's hitting at random instead of in tune with where the crank is at any given time. So I say "Yep" to your question "Maybe a new crank sensor?" : )

Testimonial: "Turns out it was camshaft sensor plug not connected"

2003 ford explorer sport trac cranks and wont start,ive replaced the a/c compressor,serpentine belt,battery twice,and fuel filter

If the fuel pump is good, you have spark, and air...And you checked all fuses, including the crank fuse. Id move into checking crankshaft position sensor and camshaft position sensors. The two sensors communicate with the computer to tell the top half of the engine and lower half of the engine the sequence that they are in if one of them isn't working correctly the car won't even know it's trying to run.

Technically even with starter fluid you should get some type of combustion, regardless though I would move on the checking of solenoids.

1998 Ford Explorer. 4.0 liter. SOHC Good fuel pressure. & good fire on plugs. Changed crankshaft sensor . Still wont crank, No fuel is getting thru the Injectors.

Car cranks wont start

run fault codes to find the faulty sensor that is not allowing the injectors to work. It may be a cam position sensor . Check that the cam shaft is turning ( broken timing belt.)

I have a 2001 Explorer Sport Trak and it don't want to start. We have checked all the sensors (crankshaft, cam trigger, fuel pump pressre is 65). What is the tank fuel pressure sensor voltage reading. ...

The first thing to check would be spark. This can be done by connecting a spark plug tester to a plug wire while the engine is cranking. The tester must be grounded to the engine block for a good electrical connection.. Your fuel pump pressure is OK.
The problem should be electrical so check
1. No voltage to the fuel injectors (blown injector fuse or bad relay)
2. No pulse signal to the injectors from the PCM (no crank or cam sensor input to the PCM, or a bad driver circuit in the PCM, or a wiring harness problem)
3. A shorted fuel injector (robs voltage from the other injectors so none will operate)
