Look for water but it will not affect the ignition and starting.
CLP/SSM= Central Locking Pump/ Security System Module.
I believe the pump/security module can and does at times prevent the engine from starting. The sirens batteries under the cowl goes bad, messes up the circuit board will feed back into the system in some way and prevent the car from starting as it is part of the Security System . The SKREEM is the Sentry Key Remote Electronic Entry Module. The CLP/SSM is the Security System Module which is the brain of the Anti Theft Alarm.
Why is it that people have removed fuse 9 and got their cars running again after Skreem symptoms; because the siren (bad batteries ruin the circuit board) had never been disconnected, fed back into the anti theft system, which locked out the start sequence. The anti theft system is more than just the SKREEM.
PS The CLP/SSM also activates the rear defroster from BCM input.
