how can i check my efi base relay

Hello, replace the relay and recheck operation -- if that's what you think has failed. You have to realize that bypassing the relay doesn't necessarily condemn the relay. Testing per workshop manual steps is required, but if you're in a position where "guessing" is diagnosis, then replace the relay and recheck. It's not an expensive investment, at least, and if it doesn't help, you know you have to go further.

Mine is doing the same thing, turnes over but won't start? Did u find out what your problem was on your car?
