Tested all plugs and sensors they all had continuity and 1ohm resistance
for the plugs so changed the (blue module) today and its gone away i got
got code 33
As early 94 probe turn key to on wait for airbag light to go off push immobiliser
button on fob start up
All codes gone
There must have been a fault in the module not (thermal fuse)
as all connectors run to the module

TIP FOR GETTING THE MODULE OUT
Take seat out remove kick panel etc once you locate the ( blue module) use a large screwdriver
or flat chiesl and prize the module off the bracket

Hope it my help a few people
