Is it true that in all cases you hear the fuel pump run?
And in all cases you see only a dribble at the fuel rail? How about when it starts and it's running ... Still only a dribble or do you get a decent spray?
And the p1312 has not returned since you replaced the DIC, correct?
- P1312 definitely implicates the DIC, but if it's not returned since replaced I'd say you have solved that.
- a dribble suggests low fuel pressure. If you suspect low fuel pressure might be worth checking the pressure with a gauge.
- if the fuel pump runs in all cases I'd say you can rule out issues with. TWICE, fuel pump relays, ignition switch, CPS etc.
- if you in fact have low fuel pressure even though the pump is running i suspect the fuel pressure regulator or the fuel pump itself.
