Question: Will not crank. Changed ignition switch. Still no crank all fuses are good. Do not know what to check now.
Answer: There are several things to check for a no crank condition. First, see if the security or theft light stays on after you try to start and it does not. When you release the key from the crank position- do not turn to off; the theft or security light should not be on or blinking. If it is, a common cause for this is the Passlock cylinder. Assuming the battery is good, next you need to use a test light connected to the purple wire on the starter and a good ground. Then crank the engine. The test light should light. If it does, then the starter is bad.
I replaced ignition when key is turned to the crank position then released the security light flashes.there still is no crank.I tried to leave key on 10min off 5sec 3 times still the same. thank you jim
If this does not correct it temporarily, the Passlock cylinder may need to be replaced. This is if the car does not have a non-factory alarm or remote start- these systems can cause problems with the factory system.
I Tried resetting the flashing security light with the cycle of 10 minutes on, and 5 seconds off for 3x. Security light stopped flashing after the first 10 minutes and just stayed lit. As soon as I tried to start the car after the complete cycle, there was no crank and the security light started flashing again.
Then you have a problem in the security system. Most likely the passlock key cylinder. This is why the relearn wont work.
I now have the security light to go out when turn to crank and release . Still no engine roll over and no power to the purple wire.
Well, if the security had a problem, now it does not, this is a problem. You now need a schematic to follow the crank circuit to find out why no power to purple wire.
