this mornin and every time i start now its hard to start ..plugs? lp? pmd? im not sure where to go first ...

 

93s dont have pmd.and i highly dought its the lp.test all your glow plugs first

 

When is it hard to start?
Hot or cold or always?
After it sat overnight?

Do the LP test anyways-while the engine idles safely in park open the water in fuel drain TEE valve and observe results-does it stall or keep running?

 

it sems to be all the time now ..

 

Check the glow plugs for power and function-pull a few and energize them and see how far they glow-any less than 3/4 of their length in a few seconds is not enough-be carefull they get real hot!

What is your cranking speed like?

You may need to check out the starter and batteries if it is a bit slow-too slow cranking speed combined with a worn IP means hard starting.
