I have a 2005 Nissan Altima I replaced the fuel pump and crankshaft position sensor and car still won't start. Has anyone had this problem before? When I purchased the car every once in a while when it starts the motor would start shaking like its coming from the floor and it would make like a knocking sound. Recently did a oil change. I don't know what else to do.
RepairPal Certified shops can diagnose and repair your 2005 Nissan Altima. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Hi this is Dusty, I'm one of the auto experts on RepairPal's Car Genius team.
I'm sorry to hear you're having trouble with your Altima, that's never good.
The shaking and knocking sounds are concerning, and it's difficult to say what's happening for sure, though a diagnosis from a competent, well-trained professional would be recommended at this point.
You've replaced some very commonly replaced components, known to be troublesome, with no discernable change and any other repairs without diagnosis would be wasteful, and only add frustration.
