[QUOTE="chodrick, post: 1992126, member: 9569"] The high pitched noise is just the electric throttle body motor doing a self check. There should be a 1 wire connector near the cowling on the firewall above the brake reservoir. I think it's a yellow with a brown or gray trace wire. That wire goes directly from the TIPM (glorified fuse box) down to the starter. If it's disconnected it won't start. You should have power on one side of it when the key is turned to the start position and you should be able to apply power to the other side and get the starter to crank the engine. I would run a jumper wire from the positive side of the battery to the starter side of the connector, if it cranks then it's not a starter issue. If it's a TIPM issue you may be able to get it started by having someone hold the key in the start position while jumpering the starter side of that connector. I have seen many bus communication problems cause a no start but I'd do the above checks first. Also the trigger wire connector down at the starter is suspect once they get hot and the TIPM needs to 'see' a certain amount of voltage to continue cranking the motor. Make sure you don't fall below 10.5v at the TIPM when it's cranking or it may stop the process. [/QUOTE]
