It just started doing this a couple months ago. Cranks a long time before starting but seems to run fine afterwards. If it sits for a short period it starts better than when its been sitting for awhile.
Generally your problem can be traced to a faulty anti-drainback valve in the fuel pump. After sitting for an extended time fuel must be re-filled and pressurized before engine will start. Second primary cause is a leaking fuel injector which does the exact same thing from the other end of the system but, this is also accompanied by a puff of smoke after starting.
Other causes can be low comrression from engine wear, or, a weak ignition coil but these are far less common.
If the drainback valve is shot can you just replace the valve or do you have to replace the whole pump?
