Question about Buick Regal
If the car turns over but does not start, try replacing the camshaft sensor and the crankshaft sensor. For the Crankshaft sensor, you may need a set of feeler gauges. This will be used space the sensor from the harmonic balancer. (see local auto parts dealer for details about these products).
If this is not the problem, have the coil pack(s) tested and replace any that are deemed bad (if equipped).
If your engine has a distributor, make sure the coil wire (center of distributor cap) is securely connected.
If this is not the issue, check the following fuses and relays:
1. starter fuse, relay,
2. ignition fuse, relay
Start with the cheapest, and smallest products first. This would be the fuses and relays. Also, see my tips for troubleshooting as well for more information.
Please let me know if you need further assistance.

Hello my name is Israel. First I am going to help you trouble shoo the problem. Be sure to have someone help you. You will need a test light or volt meter and a pair of wire strippers. Under the hood on the passenger side firewall, you will find some wires in a wire loom. Inside the wire loom you will find a thick yellow (some years purple) wire. Use the voltmeter or test light to see if there is +12 volts on this wire while the key is in the "start" position. If there is no voltage present, then you will need to get under the dash to the steering column. On the left side you see the ignition switch. Test the yellow wire here to see if you are getting +12 volts. Test the yellow wire just after the ignition switch. If you have +12 volts then the problem will be the black connected that is in the picture with the red arrow. If there is no +12 volts then the problem is with the ignition switch that is in the picture with a black arrow. Good Luck
