so..i have a 1.6 liter 1994 civic..i was having rough idle about a month back..figured would get to it later..then my car did not start one day..was an old battery..so replaced that and replaced all the ignition components too..caps..rotors..wires..spark plug..

now my engine doesnt start in cold weather..and i live in MN so..i'm thinking one of my injectors is fouled as last time it flooded the engine and i had to use a hair dryer to dry it..also i used to get bad gas economy..around 15miles to gallon...do you guys have any idea what is happening..is it the fuel regulator..or the fuel pump itself..or how do i test all those to find the culprit..in need of serious help..

thank you

 

take the main fuel relay out and inspect it for hairline cracks in the soldering points

 

sorry its a 1995 civic..also could you tell me where the relay is..is it in the fuse box??

could it be a fuel pressure regulator problem??

 

its under your dash on far driver side.

 

also..my fuel guage doesn't give accurate reading..it fluctuates..all the time..

 

ok will try that..

 

do i need to replace that or resolder it..

 

you can spend 40$ and replace it or spend 0$ and resolder it... up to you
