Hi all,

Stumbled over this forum, you guys appear to know your topics smile

Have a problem thats got me good!

Detroit 50 application on a Bus

Batteries are new / Starter is new.

Ignition when switched one does NOT light up the CEL or SEL lights! (They work on the test fine) (they should light up for 5-7 seconds on ignition).

The Oil pressure light is lit at this point (from what I've read the OP will not stop the CEL OR SEL from being lit)

Engine will crank, just about fire up and then go back to cranking only.

One day it just started doing this, everything pointed to low batteries but replaced them, grounds look good, ECM is getting voltage.

From What I can tell the oil pressure sensor is via the ECM but at this point I have no idea if the ECM is good or bad.

Any suggestions?
