Changed the crank senser on 1992 buick lasbre 3800 and car still will not turn over and start

go buy a service manual

You need a wiring diagram to join a yellow and an orange wire together? Most people who aren't attempting to steal a vehicle use the correct key. Or am I missing what you are trying to ask as there is so little information in your question?

go get a service manual

check the firing order to start with . Next see if the cam shaft is turning (broken belt/chain) Next check ignition timing is correct.. Check for spark as it may be the immobiliser is not working.

Does it have spark? Does it have fuel pressure? Was there a reason to change the components that have already been changed?

That would be an aftermarket part. Although I am sure that Standard Motor Products, parent company of BWD or (Borg Warner Division) probably makes some OEM items, if it is labeled BWD it is from the aftermarket parts division.

dont replace anymore til u know the cause--test for spark 1st-it may just be the ignition module--a worn coil--or bad distributer cap--battery cud be too weak and old-or alternator is------fuel pressure may be weak---------aftermarket electrics dont always work well either--a diagnostic scan can help at a privateshop

the motor is not getting enough gas. check the gas pipeline

You may end up spending a lot of money on parts you might not need. find a mechanic.

Try disconnecting the negative cable from the battery for a couple of minutes, then reconnect it. This will cause the on-board computer to reboot. It may then, recognize the new crank shaft sensor. It's worth a shot and won't cost you a dime to try it. Good luck! Hope you get it started. Bill
