2000 Pete won't start won't flash codes

[10whlrchick]

I have a 2000 pete w/detroit 60 series 500hp, cranks but won't start.
Before I shut him down both check engine and stop engine lights were on but holding diag switch would not get any response. now it will crank but not start.
can any body help?

is it possible to get a Read out when you just turn the key to Accesory position?
Might be your Fuel Pump if you haven't checked that out.

[10whlrchick]

With key in accessory position I get no loghts on dash. Already took apart fuel pump don't have a presure guage but with output line off fuel flows out when cranking, gears in pump seemed ok although there was significant play (up and down) in the shaft with the fixed gear that connects through the pump body to the drive gear

[pheobo]

um... maybe it's the secondary pump aka injector pump? Have you checked individual injector feed lines to see if they pump fuel when cranking?

If you're sure you're getting fuel to the injectors it could be injector signal is off for some reason - I doubt your injectors decided to go with no notice and all at once.

Is there any air in your fuel return line when you pulled it to check?

Seems like the kind of problem I like working on, good luck.

Where is the injector pump located?
Is there a way to check for injector signal when cranking?
Do you have a schematic for this truck?
If I knew which circuit provided the injector signal from the ECM I could backprobe at the connector on ECM while cranking.

pheobo if this is the kind of problem you like working on, then perhaps you might have a service manual that has wiring diagrams, schematics,
and especially a symptom/cause troubleshooting chart that you could scan and email to me :P

If your not getting anydash lights MY guess would be your problem may be electrical or in the computer.
The first thing I would do is see if there's an 800 number for Detroit. They probably have some kind of help line you could run your problem by. In fact a friend called a Detriot help line awhile back and was impressed by how helpfull they were.

Check just behind the battery box. My 2001 had a fuse holder that burned through. The engine would turn all day but not start. The ecm wasn't getting the signal the start.

[ChrisSai]

Behind the battery box there should be a large round connector. I have heard of them coming loose and not making a good connection. I would start there. Did you have the dash panel apart recently?

I can't find a fuse holder behind the battery box anywhere, I'm not saying there isn't one back there have many components mounted in that area (air tanks, etc... that prevent me from seeing or feeling any fuse holders.
could you tell me if it is mounted on the inside of the frame rail or ontop of the frame rail under the drivers door of the cab is it an inline bus type fuse holder if so haw many amps is the fuse.
Perhaps if I knew what circuit it was to the ecm I could check for power at the ecm.
I appreciate all of the help

If both your engine lights were on, it is also possible that you have another problem. Like low oil pressure or low coolant. The computer sensed something wrong, or a sensor sends the wrong signal to the computer and the computer is ignoring your desire to start the engine.

I had a 387 that would start when it wanted to start. Finally on a road call the mechanic said relays work out due to vibration. Pushed all relays in and truck started. I later spread open prongs on all relays and never had problem again. This was a simple fix to a perplexing problem. I hope your fix is this simple. Good luck!!

It saddens me that nobody has yet corrected this misleading post. 60-series Detroits have neither an injector pump, nor injector lines. Just so you know.

There is a in line fuse in the battery box near where the cables go towards the engine. also if there is an auto shut down hooked up there have been instances of the module on the starter that prevents it from cranking to long and overheating going bad. Bypassing it will allow engine to start.

If the cel/sel do not turn on momentarily when the key is turned to the run position, then the ecm probably is not being powered up.

Disassembling the fuel pump without a pressure test is silly ;0)
...you could cause damage to a system that WAS fine. Detroit has issues with the pump drive seals leaking, but not a lot of pressure problems.

You're asking where the injection pumo is on a s60... and, you're going to be backprobing a pulsewidth modulated injector circuit??? Wouldn't I love to be a fly on the wall of that service bay... LoL

You need to first verify that the ecm is powering up, then make sure the ecm is seeing the key-on sequence... you can backprobe injectors later ;0)

The ocp (over crank protection) thermal switch on the starter WILL NOT allow the engine to crank at all... when it fails.

Is there a diagnostic (diag) switch in the dash?

If so hold it on, and then turn the key forward to the run position... this should start flashing codes; A 25 indicates no faults, it would blink the check engine light like this; "blink" "blink" ...then a pause... and then; "blink" "blink" "blink" "blink" "blink" = 2 5 ...fault code 25! If it blinks anything other than 25, let me know.

Somebody already mentioned it, but make sure the coolant level is not low... this can cause a no-start.

AGAIN, if the "check engine light" and "stop engine light" DO NOT come on AT ALL when you turn the key switch to the run position, the ECM is not powering up (with VERY few exceptions).
