I had a 2002 Dodge truck and I could turn the ignition over 3 times without starting and the code would flash. Then look on the net for the codes' meaning.

Just "Google" the code you are looking for and you should find the information your looking for.
On Google
how do I find the codes on a 2002 FLHPI
On the top of the battery look in the engine compartment directly above the battery.
It is your "check engine" light. It is telling you that something is wrong with the engine or engine controls. It could be minor or major. You will need to get the "codes" read to find out the problem. Use a code scanner to find out what is wrong.
turn the key to on and then off 4 times. any codes will appear in the mileage box. If there are no codes, it will read p done. If there are codes it will show P??? and then P done.
If the check engine light is or has illuminated, have it scanned for codes. They may help find the cause.
first off it depends on the year , the manual I have covers 95 thru 99 and there are no such codes in it !? Good Luck !
Yes, it is very important for you to find out the correct engine code for your car. Honda specifically posts these engine codes for cars to help you with your new car.
ford, chevy, or dodge?
The most common problem is a oxygen sensor. To figure out you have to read computers codes out, and find out the reason.
