I have this problem some ppl had this solved by adding a 1 way fuel line attachment since the problem some ppl say is that there is a leak in the gas line and the fuel would back up towards the filter leaving an air bubble in the line. and by puting this one way valve thing it would solve the problem by not allowing the fuel to back up. it helped a bit but it still takes like 2 to 3 seconds of cranking before it starts from cold. once i drive it for a bit it starts up good. and i remeber this being a very cheap part i think it was like $5 its basically a hose and a one way valve attached to it.
I've had the same problem sorta...my car has had the relay, the sensor, and fuel pump changed...and everything cleaned...when i bought it...it started up great...now it cranks for ever...what is the deal...my dealership has no idea...PLEASE ANY POSSIBLE FIX...every possible problem tell me...its embarrassing to start this car in front of a girl...let me know
see my other post on hard starting as well...I know there is someone out there that knows there stuff backwards and forwards
