I'm having issues with my car starting. I've replaced the crank shaft sensor and the fuel pump relay. I've had the fuel pump tested and it was good but when I turn the key it doesnt come on...... not sure if it's an wiring issue or what. Its been looked at two mechanics and both can't pinpoint the issue. Does this means I just need a brand new fuel pump?? could it be something minor like the fuel filter.... it pretty much starts when it wants to .....sometimes it takes me 30-60mins...sometimes sooner. Very annoying and frustrating. Has anyone been through this
