TRIED TO CHECK ENGINE LIGHT SRS BLINKS AND MY CHECK ENGINE LIGHT BLINKS MAD TIMES LONG ONES NEW VTEC OIL PRESSURE SWITCH TOO

 

In adequate oil pressure and coolant temperature can cause VTEC not to engage. Check your oil pressure, you can also back probe your coolant temperature sensor with a ohm meter to ensure it is working properly.

 

how do i check my oilpressure

 

uhh try to get it tuned...running that setup with a stock p72!! not smart at all...your killing your motor

 

To check oil pressure you need either an external oil pressure gauge used to monitor the pressure or there is a oil pressure gauge tool that screws into the existing O/P sensor location on the back side of the block.

BTW what code was it giving you?
