oil pressure switch OPS

 

Cool,i seen some where with all the abbreviation's but couldn't find it.Would the OPS from my 1993 6.2 liter fit on my 1994 6.5? So if it does fit ill swap out both parts from my 93 to my 94 and hopfully it will cure the problem

 

not sure if 6.2 and 6.5 inner changeable

Checked it out and its the same oil pressure switch # so im good to go.Ill try to fix that today and tnx for that auto site very easy to get around

 

Well i changed the OPS and still the pump wont start up unless its jumped at the fuss termanal.It was the old switch out of my other truck but every thing ran fine on that truck,as soon as you turned the key the pump started and shut down when the ip was primed.ill go back and read some more i guess,.

 

is your glow plug system working right i know LP will say running in till the relay shut off then after truck start then LP start up again when see oil pressure and then when you shut down truck it stay running in till oil pressure drop to 3psi

 

Yes its working fine,i turn the key and the lits comes on for about 20 to 30 seconds depending on how clod it is out side then the truck fires up,coffs a bit then evens out and runs fine but i never hear that dam pump run,.The only time i hear it is when i jump it and i can hear it clearly .

Im going to take a video of the truck starting up and put it on youtube then post the link,maybe you can get a better idea ?

 

well one way tell if it working is start the truck open the T-Valve see if fuel coming out and if the truck stay running if does the LP should ok

 

Ok as soon as i get a chance ill try that.I started it this morning and after running for a few miniutes it stalled,i restarted it and took a fast spin,let its sit running for a bit then took off and made about a 1000 feet and it stalled,ugggg.Restarted it and made it home and now i gotta work on the loader so ill try that later on when i get a chance Crazy...im starting to think i was Crazy for buying this truck,.

 

That also sign of PMD going bad
