Hello Peter, It doesn't look good but I found this. •Fuse #7 under the steering column powers the SKREEM module and the horn. If you have a "start error" and the horn is not working check this fuse.
•Sometimes a dead or low battery will cause a "start error". If you have a low battery, disconnect the negative battery cable, charge your battery, and then reconnect and try starting again. Leave the battery disconnected for a length of time before reconnecting.
•If your van will not start and the engine cooling fan starts running as soon as you turn on the key, this usually indicated a faulty engine computer. If you try to scan the engine computer you will find it will not communicate. Replacement will be necessary.
