Ignition Switch Replaced but Olds Intrigue Still Wont Start

Will not crank. Changed ignition switch. Still no crank all fuses are good. Do not know what to check now.

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

OK, you have a theft system problem.This is not the correct theft re-learn procedure you are doing. See this link below. It is for a Chevy Impala, but is the same for your Oldsmobile...

Theft Relearn Procedure

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.
