Well not knowing what kind or year of vehicle it is. I'll take a generic stab here. If you've changed the pump and filter, and you're not running a mile of rubber line on this vehicle, then I'd say go after your fuel pump regulator. (easy way to check is if the vacuum line going to the FPR has gas in it when you take it off then the FPR is probably bad. Another thought is (with some helping hands) start the vehicle and while its just starting to run rough like it's going to die, press the scheader valve on the fuel rail and see if it has a good volume of gas coming out of it. if not then trace backwards to the FPR. it could also be the fuel pump relay under the hood, you should have 2 or 3 relays that are identical, try switching one around and see if it stays running. Hope this helps.
I Think Your Problem Is Still With The Fuel Supply,Have You Changed all Fuel Filters,Follow All The Fuel Lines Make Sure There Are No Kinked Fuel Hoses,Some Times You Find Small Filters In The Top Of The Fuel Injectors. Hope This Helps
Need year/make/model/mileage of vehicle to provide a more specific set of troubleshooting steps.
When was the last tune up? Hard starts when cold are usually caused by fouled spark plugs, worn plug wires, or weak ignition coils. Fuel systems are not as effected by temperature changes as the ignition components.
Have your temp sensor checked. It may not be setting off a code but a sign of a failing temp sensor is hard starts, rough idle, until the car heats up. It sends a code to the ECM to help adjust fuel mixture. If it sends gals readings, the computer will adjust the fuel-air ratio and cause vehicle to run too lean until warmed up. Some people have had to keep pumping the gas pedal to keep it going from a bad temp sensor.
try checkin your idle air control. most of the time it is a vacuumn line going into intake.pull it off and if the car revs up dont worry, it wont hurt it. if it does simply put it back on, if it dies you have a bad vacumn.
seem like you got the same problem as my scion xa, check the fuel pressure regulater. bad regulater some time smell like leak gas. auto zone might cause you about $80.00.
try a good service as been standing a long time
