i have 90 accord dx 4 dr, lately when i turn my car on, sometimes it won't start, it cranks but doesn't start..i have to wait about 1/2 to 1 hr or the next day and then try it again and then it starts. I took it to mechanic and he told me my fuel pump was good and that it was one of my wires connected to my pump that was burnt out, he replaced the wires. But 2 days later, the same problem occured, now he says that the fuel pump has to be changed. Some have told me its my starter others say that it's my relay that's burnt out-(related to fuel pump, under the dash). can someone please advise and assist??
