The common cause of the problem that you related.
Is the FUEL PUMP RELAY " Called MAIN RELAY.
Is located : left side under the dash.
Is a BIG relay gray colour. with a connector of 7 or 8 wires.
I recomend replace the relay.
And letme know if you solve your problem.
I hope this information work on your problem.
Thank you for use fixya.

If you replaced the fuel pump then there is a possibility that during the job then some debris from the tank and/or filter got loose somewhere into the fuel system and is in your lines. It could even be a very tiny speck of gasket material, old or new.

Replace the ASD relay,but first check the relays powers.One power feed battery and the other one is key on.
