1998 Mitsubishi Mirage
Stopped while driving, no start

Car is a 1998 Mitsubishi Mirage LS.

Driving down the highway the engine just died. After stopping in a safe place the car would not start. I had it towed back home, away from the noise of the highway and noticed that it did sound good when I tried to start it.

We thought that maybe fuel did not get to the engine, looked for a kill switch that might have tripped and looked at the electrical diagram for the fuel delivery and electrical system.

We were able to confirm that the fuel pump worked by connecting connector A-53 directly to +12V and hear it start.

Next we turned our focus to the MFI (Mutiport Fuel Injection) system. Here is the electrical diagram.

Starting at the top we checked for Fusible Link #7 and found that it was opened. We replaced the fusible link and the car started. So we had found the problem but not its cause, something made that fusible link melt.

Since fusible link #7 deals with injectors and a few other sensors I decided to look around the wiring harness in the engine that were going to the fuel injectors and noticed that one of the wiring harness was rubbing against the engine lift bracket to the point that it had puncture the plastic protection.

Jiggling the wiring harness produced a few sparks (shorted to ground).

The culprit was found and repaired.
