Hello Forum,
Car turns over, but wouldn't start. Mechanic said it was Fuel Pump, and replaced pump. Car now turns over, with occasional rumble in rear. It starts easier when cold, but when HOT it turns over but DOESN"T start until given some gas with pedal....frustrated.....Thanks

filter,fuel screen, or wore out fuel regulator? I only buy pierburg pumps, not bosch

need to check fuel pressure. the pressure regulator is part of the fuel filter and may be bleeding off. a new pump SHOULD have gotten a new filter.

ok, it still needs a fuel pressure test. just wrong about the regulator placement.

yeah they loan them at advance, connects at scharder valve on fuel rail.
