Hello,
Replaced Fuel Pump for previous problems starting car. Pressure readings with new Fuel Pump in correct range (41 - 47) when replaced.
Now 1 month later having same issues with starting after sitting for a while.
Took to shop and fuel pressure readings are as follow:
Key to ON position- pressure shows 45 for the 3 seconds the fuel pump runs, then drops to 41 and holds.
Start engine and fuel pressure reads 35.
Turn off engine and pressure drops to 32. After 15 minutes it reads 34.
Checked FPR at idle and no signs of leakage.
Could FPR be bad and not indicate so with idle test?
Any ideas where to look?
Thanks,
