Hi, was the engine out of the car? The reason I ask is because on the back of the crankshaft the crank sensor reluctor plate is attached, if it is missing,installed backwards(I'm not sure if it's possible)or installed incorrectly you will have no spark .You can check if the plate is there by removing rubber cover beneath throttle body,let me know ,if it's there the teeth should face towards front of car,thanks

Ok . Car was involved in side accident , came to us runs n drive . Left for 7 days battery died . Jumped it . No spark no fuel . Changed Cranck and cam shaft sensor . No fuel no spark car crank . Ground to ecm is checked , j think it could be jumped wrong . Which fuse or relay protects it . And could be the main fuse box need replacing
Subaru Mechanic: tamaz, Subaru master technician replied 1 year ago

Hi,the main fuse in box in engine compartment would be the fuse protecting the circuit if it was jumped backwards usually,if this was the case you would have nothing ,no lights on the dash ,no crank,just nothing.Let me look at wiring and see if I could give you something else to look at

Ask Your Own Subaru Question
Subaru Mechanic: tamaz, Subaru master technician replied 1 year ago

Hi, please check all fuses but the ones in particular to look at is SBF-7 this is a 30 amp fuse in main box under hood ,there is a diagram on the cover to help locate it,in the car there is a fuse box and along the side of the box there is a additional fuse box check all fuses in this box also.If fuses are good inspect for voltage on brown/white wire on any coil you should have battery voltage, blue/yellow is ground and other wire is ground signal from ecm.
