I HAVE A QUESTION IN REGARDS OF MY CAR MY WIFE WAS DRIVING IT AND IT SUDDENLY JUST QUIT I HAD WENT TO THE NEAREST PARTS STORE AND ASK THEM IF THE COULD HELP THEY TOLD ME IT WAS EITHER THE CRANKSHAFT POSITION SENSOR, OR THE IGNITION CONTROL MODULE. WELL I REPLACE THEM BOTH AND I AM NOT GETTING ANY SPARK, SO I REPLACE THE IGNITION COIL PACK. THINKING IT WAS THE PROBLEM STILL NO SPARK SO I RENTED A OBD-II TESTER IT SAID THE CRANKSHAFT POSITION SENSOR WAS BAD I REPLACE THAT AGAIN, STILL NO SPARK COULD IT BE THE (MFI FUEL PUMP RELAY)?

Trace the wiring harness for the crankshaft sensor and make sure it isn't damaged or open. This will also give a bad sensor indication with the code scanner if the circuit is open. Hope this helps

Suggested Repair

Inspect the crankshaft position sensor wiring harness for damage or an open circuit, which can trigger a false bad-sensor code and prevent spark.

Conversation Summary

A Mitsubishi cranks but will not start and has no spark. The owner replaced the crankshaft position sensor twice, the ignition control module, and the coil pack, and a scan still reported a bad crankshaft sensor. They also asked whether the MFI fuel pump relay could cut power. The expert advised tracing the crankshaft sensor harness for damage or an open circuit, which can cause the same scanner indication.
