When I go to start my car and "bypass" accessory on my ignition my car has a very hard time starting, if at all. If I put my ignition on accessory I can hear a odd "noise" coming from the rear of my car, about far back as the rear wheel. The "noise" goes away after 2-3 seconds. If I wait for the "noise" to stop my car would start up. Now the problem is getting worse, even if I let the "noise" go away my car is still having a hard time starting. I remember my dads van doing this and it ended up being the fuel pump. Just want to semi-verify before I buy the part.
Car has about 127,000 miles on it.
