Went for a quick ride.
The truck ran great until I looked for a parking place.
It was like turning off the key.
Usually it kinda acts like it's ran/running out of fuel.
Not today: I had a new GM OPS and put it in.
Nothing!!
I had bought the kit from Leroy and installed it.
Along with a New Bosch...
I've been afraid to go far!!
It died again today.
Tried a different PMD and it made no difference.
Changed to the spare(new) OPS and it started right up?????
Ordered the harness and relay from Leroy Diesel.
Should get here Mon/Tue.
Sure hope this helps?
Now would there be a problem in the...
Not sure where the ops was bought that was on the truck???
Very possible A.Z. or Advance.
There was a new one(a.z.) along with a socket in the glove box.
The PO told me about them going bad.
I replaced the original a while back.
I used the one in the glove box (from A.Z.)
It worked for a week...
Put in a new ops.
Runs!!
Why would it go bad so soon?
Something in the system to make it do that?
Is there any way to jump the plug the next time it goes?
I'm gonna carry a new one now.
The place the switch was plugged in was way deep down in the back of the motor.
Would it hurt to extend...
Did it again?
Someone mentioned the PMD
Would this affect the starting the same way?
I have a spare PMD just not sure it's good.
Any way to test it?
Thanks for all the help!!.
So what kit do I need to order?
I see kits on Leroy's page but need to know what to order??
This what I need?

What would getting the relay harness help??
When I first got the burb I did a whole lot of reading and working.
Po had replaced one head and not the other.
I did the head and the radiator, fan and injectors and lots more.
Seems to be FIXED!!!
Replaced the ops and it's running!!
When I bought the truck a year ago.
The guy said to look out for that problem.
He even included a new one and a socket.
I replaced it and it ran for a short time.
Then stalled again.
I'm guessing it was the wrong sender??
Or a cheapo. It...
The tank should have pressure in it?
The lift pump has good pressure.
I open the filter and lots of fuel leaks out.
The tiny petcock? Same there.
Gonna try the ops in the am.
Thanks.
I've jumped the lift pump and the filter is full and the drain has lots of fuel coming out.
I turn the key and it runs for a second then dies.
The injectors have fuel leaking out when I loosen the cap nut as I turn it over.(I bled the lines)
Sounds like a sensor or pressure switch or something...
Hi, I have 1995 Suburban 1500
It has the 6.5L Turbo Diesel.
Full tank of fuel.
Yesterday driving down the road it acted like it was running out of fuel.
Stalled and towed home.
No fuel at injectors.
The lift pump only works if I jumper the lugs in the board where the relay plugs in.
It pumps...
