Just replace the bad stock fuel pump in a 91 Honda Civic with a Walbro 190. Everything seemed good for about a week, then it died on me.
The starter would roll over but no spark and fuel.
The main relay was not clicking and no power to the ECU.
After looking at everything, I found a blown fuse and replaced it. Turn the key on and it popped again.
Unplugged the fuel pump, replaced the fuse and did not pop.
Dropped the Check all the wiring and rewired the ground wire in the tank.
Does not seem to be blowing the fuse.
However, the pump does not seem to be getting 12v. It is pumping but strong.
