I have recently attempted to change my filter and after removing the part and reinstalling it the car will no longer start. The fuel is going up the line to the engine however I think that it is likely not sparking, although I have not been in the engine for the swap. However, I'm unsure and have ended up here. The car has been serviced fully up to this point (160000kms) so im not sure why anything would be wrong.

Things I have currently done to try to get the car to start,
-Manually powered fuel pump
-Checked Fuse box for any faults and didn't find any
-Had the battery hooked up during start attempts

Any help would be appreciated

 

The model is 07 1.5L VTI
