alright i read up on the main-relay problem...and found it in my car...seems like a simple fix.
but let's say that this doesn't fix it...the fuel pump would be next correct.

remember that the fuel pump does engage..it just takes some time for it to do some (more often than not)
if the car has been running or is still a bit warm..it takes anywhere from 5sec to 30sec.
but if i try to start it up from hours of sitting, it takes 30 sec to 2 min...so let me know
