Civic hybrid starts then dies
 

Hey how’s it going I have a 03 civic hybrid and everytime I first start it it rough idles for a sec and dies or it will just die I have to put my foot on the gas but after that it won’t die . I ran the codes and it has a misfire on every cylinder . And a random misfire . Anyone else have this problem ?thanks

If you leave the key on for like 30 seconds before you try to crank it does it start fine?

Multiple misfires should rule out anything specific to one cylinder.

So it's probably not
-injectors
-coil packs
-plugs

-most likely since you need to give it more throttle and you have no air related codes, like IACV codes, its fuel delivery related.

Check ignition pulse at the injectors and fuel pressure at the rail.


If these check out do a generic once over
-grounds/battery connections
-fuses/relays
-check for strong spark at plugs (white/blue)
-and of course we've already checked fuel pressure at rail and injectors for pulse.
