It just stopped … on the go

Lyrica order form I was heading home and my car started running rough then my car just shut off. Did my fuel pump die?

What Vehicle? 1998 Nissan 200SX

If you let it sit for 10-15 minutes does it start back up? No

My first guess was that the fuel pump or fuel pump relay may have quit.

Worn but still OK plug

Oily, but good spark plug

Final diagnosis:

The three basic things you need to get an engine to start are air, fuel and spark. So we start with those. I started by putting an inductive sensor on the #1 plug wire and cranked the engine. The sensor was picking up a signal, but it wasn’t at the regular rhythmic cycle that I expected, so I suspected something in the ignition system. I pulled the air filter to check and see if there was anything blocking it, but it was good. Air system is most likely not the issue. Next I pulled the plugs. Plugs smelled

of fuel, so I could most likely rule out the fuel system. Plugs looked normal except a little oily. I reinstalled them and worked up the ignition system. I pulled the cap and something fell out on the floor when I removed it. Initially I thought it might have been the carbon button in the center of the cap, but I was wrong. I looked under the car for the item that fell out and found a small screw. On inspecting the rotor I found that on this particular vehicle the rotor is held in place with a screw that comes in

Distributor Rotor was why the car just shut off

from the side and threads into the distributor shaft.

Solution:

Reinstall the distributor rotor and screw with a half drop of medium Locktite. Cleaned up the inside of the cap and the rotor contact. Reinstalled the distributor cap. Started right up.

Conclusion:

Now you have a start on how to diagnose a no-start situation when you car just shut off.
