ICM burn up 99 Olds silhouette 3.4

Unread post by rschneider » Thu Dec 22, 2016 5:29 pm

The van was fine, then a 30 mile trip turned it off. When restarted SIL came on then started flashing. P0303 code tested plug,wire ,coil all ok. Decided to test ICM it tested bad EST/Spout circuit is bad! New ICM installed, flashing SIL took new one for testing. Failed EST/Spout. How to test ECU, X7/X24 CKP, CMP sensors. Any other ideas? It's Mom's van and she is impatient! HELP PLEASE and Thanks
