Does the yellow check engine light come on when the key is turned to the on position?

Customer reply replied 3 years ago
No. This is not original engine. Assume check engine light be on the tach or odometer.
Technician: Cat Man, Cat Engine Expert replied 3 years ago
Normally there is an independent yellow light on the dash. It should come on then go off every time the key is turned to the on position.

I will call in about 2 hours. Terrible phone reception where truck is located. More info - checked all fuses and all are good. Checked all electrical in battery box and all good. Truck chassis manufactured 11/90. Think engine is a 92 model.
Customer reply replied 3 years ago
Ok maybe I can try later. When cranking engine oil pressure is not moving. Could this be problem. Know there has to be oil pressure for injectors to open.
Technician: Cat Man, Cat Engine Expert replied 3 years ago
Oil pressure will not cause a nonstart.
You may want to check power to the engine ecm.
