I have a check engine light and i took it to Autozone, but they never gave me the code only the problem. So i was wondering if you could help me decide what OBD II scanner/reader would be a good choice. thanks in advance

I have a 1996 Ford Mustang GT with a 4.6 L V8 and Autozone didn't give it to me because he never looked at the code only the problem.

What is the year and model of your car?
And is there a reason Autizone would not tell you the code they usually do.

A OBD scanner will only set a code for the crank position sensor only if it sees it is electrically malfunctioning. If in resistance, you can't determine it without a o-scope as someone said. Ford crank position sensors will be intermittent sometimes but very rarely go down without setting a code. Cam sensors also govern fuel and will sometimes fail at higher RPMs without codes But no fuel spray and intermittent spark worries me. But many things can cause those symptoms including a fuse being blown (powering the PCM) but the crank is usually checked by Ford techs with a thing called a break out box and a a/c voltmeter (the break out box allows the tech to "go between" the PCM and the vehicle harness to accurately gauge what is going on. You can check the tooth ring on the crank pulley and if extremely worried , change the crank sensor and retest but without seeing the vehicle, I can't tell you (BTW, are you sure he is getting 12 volts at the fuel injector on the red wire and that the other wire is pulsing when cranking?) Also the fuel pump will run for a few seconds when you turn the key on independent of the crank sensor... so if after 5 turns of the key, if you don't have fuel pressure, it's time to look elsewhere and almost all tauruses use a timing chain that I'm aware of (only some of the older SHOs had a belt if I remember)

If you live close to an Advance Auto Parts store, take it there and borrow the OBD II tester..depending on what the code reads they will be able to look it up in a book and tell you.. if it's not in the book you'd have to call a dealer. At Advance the OBD II tester is between $50-$75. Sorry can't remember which.

The little $50 you can find at most auto parts stores will do the job.

Go to Harbor Freights. They have one for $40 bucks and works fine.
