Detroit 60 crank no start

Some have a little fuse on the wires near the battery for the ecm .

 

There’s a check valve on the back of the head that feeds the fuel return line. If the check valve is shot you won’t be able to get enough fuel pressure that the ecm has to sense before it will fire the injectors.
Also i had one that lost its fuel prime due to air getting into a fitting of one of the suction lines to the tanks.
A fuel pressure gauge would help in both these instances.

 

but is that possible after been workin Perfect, just next day don’t start. ?
I’m asking because I have the same problem right now

 

The TRS and SRS - if one is faulty it prevents start, if the other is faulty it prevents run.

What was the original reason you changed them 4 months ago?

I had the same issue a couple of years back - ether started it, I didn't shut it off till home, replaced TRS/SRS and never happened again.

Ditto the above advice on verifying fuel flow too.

 

Pull the timing sensor out behind the air compressor and see if there is any metal on the probe end. If so then you have something going out on the front. Does the check engine lights come on when you switch the ignition on? If not then there is no power to the ECM. Check the fuses and the wires in battery box to make sure they are not losing power. I usually take a headlight and run wires from it to the power connector that hooks into the ECM to check the grounds and positives on the power plug. If you have ECM power and the timing sensors are ok then I would look at fuel pressure issues.

 

Right on the money!!!
