need help with an 02 sunfire that won't start unless it feels like it.
ok so when you turn the key on the fuel pump relay makes this strange humming clicking noise and the car won't start, if it doesn't make the noise it usually starts, so i tried replacing the relay but that did not work same thing happens.i checked and cleaned battery connections they look fine no other fuses or relays seem bad. but i was able to get it to start and drive it back to my place from where it was which was about 10 minutes away and it drove fine but now it doesn't want to start again.
anyone have any ideas on where to start next.

 

Better consult the dealer.
