Need Assistance with LMTV in Jacksonville, FL

[byrdman1312]

I'm having problems too,with LMTV's. I don't think anything like these. When I turn on the switch, I get power everywhere. When I push the red button, all I get is a "bump" of the starter. Will not turn over, just bump.
Tried to start it yesterday, hooks slave cables to a HMMWV running high rpms, just a bump.

Sometimes it may bump a couple of times and then start.

Anybody? Any ideas?
Thanks,
Keith

Starter, aux starter solenoid, start relay in panel or bad start button. I would start with the relay in the panel you can jump the contacts with the relay out and see what happens. Top to bottom should crank it.

Byrdman1312 sounds like you're not getting enough power to starter or you have a bad starter. You measure voltage at starter or pull starter and have it tested

 

[Suprman]

Some of the earlier style starters have a thermal protection that is known to go bad creating a no start condition. But its very easy to go step by step and diagnose.

Anyboby know how to get a sears riding laws mower to crank over???? No seriousy HELP

Troubleshoot. The first gen trucks dont have an engine computer.

It's not really a first Gen, though Not a second Gen, either

 

[Suprman]

The one with green pcb power panel is an A1 so second gen.

Can someone remove their h2o/ fuel separator and pto circuit breaker and see if their truck will start or try to start

Low battery voltage, or bad power relay.

Anyone? Will truck start without PTO/FUEL SEPARATOR Circuit Breaker?????

Try and use one from a non-essential circuit, like the crane CB

 

[Nearcoastal]

I have tried swapping them and Installed a new cb the problem is that there is something on circuit that keeps tripping the cb. I'm just trying to figure out if the truck will start without it to determine if I need to focus my time on something else to get engine running.

 

[Suprman]

Look around the drivers side of the trans thats where the pto goes its electric solenoid engaged. Maybe a wire is pinched and shorted somewhere. You could probably just leave it out.

 

[Nearcoastal]

Is that circuit breaker also for the winch?

Will a missing oil pressure transducer(sender) cause the engine not to start?

I don't think so but it will cause the alternator to not work.

 

[Suprman]

Interesting. You can jump the 24v positive from the fuel solenoid and go to the regulator 24v contact to make the alt work.

 

[Nearcoastal]

True about alternator but still trying to get ecm to tell injectors to inject.

the lack of oil pressure sender might be the culprit, at least it's one step closer to get her running
