Does any one know what this 10 amp fuse is for?? Its for the alternator solenoid valve?? It keeps blowing when I attempt to start that car. Would that keep my car from running? I have a 1990 civic dx hatch with OBD1 Ls swap. It was running fine and I was driving to work cruising at 55 mph and all of a sudden without a warning my car shuts off and I coasted down to a stop. It cranks but doesnt run. The fuel pump isnt working and I dont have spark. I thought it was the Main Relay and I replaced it but didnt fix anything. Anyone knows wat it is?

 

Fuse # 14 controls the following:
Voltage Regulator (IG)
Emission control solenoid valves
PGFI main relay
PGFI-FI ECU (IG1)
Fuel Pump
ELD unit
EACV

Is your fuel pump stock or aftermarket?
{Aftermarket have been known to blow the fuse}

You might have the alternator tested..
If it is overcharging,it will pop the fuse..
Also:Make sure all electrical connections are tight..

 

Something might be shorting out, when I swapped my D16A6 into my Civic it kept blowing that fuse because of the purge solenoid wiring. That might have also been the reason my ECU went all screwy too

 

i had this happen after my obd1 swap.i had the 4 wire o2 sensor wired incorrectly.

 

Wow really? Thanks for the info 99DXCRX! I dont know what fuel pump I have but I know its the same one since I bought the civic with the single cam zc. I have had the swap done last year fall. I drove it a couple of months and it sat from January of this year to about last week. So its been a while. The only thing I did was switch from a hydro gsr trans to a b16 cable trans. and then 131 miles after doing that my car shuts off.

 

not trying to thread jakc but, mi car only blows this fuse when i get on it or when i downshift, 88std, mpfi swap, relocated batt

 

only advice i have is to check all the wiring to the listed in the post above.
