Well after a new fuel pump and UIM my old GP is running pretty well. However when I shut it off and go to restart it (warm restart, 20 or 30 mins later) it does alot of cranking (10 to 20 seconds) b4 it starts.

Sometimes I can smell gas, and the oil level has risen about 1/2 a liters in 2000 kms.
This car has 265000 kms on it, Just wonder do injectors go bad and start to leak? (familar with this in Diesel mechancal injection) How does one test them and should I change them all?
