Okay, now can confirm after testing it all and found out that the new oil pressure sensor for VTEC has failed and snapped off, replaced it and now VTEC works.

Been having a lot of other dramas with my engine since I've had a lot of rain in the city i live in, and minor flooding. The car seems to stall and die out then hard to start, i have to let it sit for about a minute before it will fire again, can sit there and crank it though. idles really low sometimes. Only does this once engine is warmed up. Then other times it runs like a treat.
Ive check voltages and readings from all sensors and they are fine.

Also park/cluster/tail fuse keeps on blowing, no matter what fuse i put in it, fuse is fine until i turn the lights on which makes it impossible to drive at night. Ive checked all bulbs and they are fine, even the cluster bulbs and dash lighting. Also have checked dimmer switch.

Any help would be much appreciated.
