0m602 93 when I try to start it the motor turns over but I get a grinding stripped out sound from around near in the IP. What are the usual suspects?

Broken timer teeth, stripped IP splines, broken IP camshaft.

If that's it, serious repair or new motor.

Can I get to all that without pulling the motor? was wondering what winter project I was going to work on, guess I found it

You can get to the IP, but I think taking the timing device out is a big job.

The problematic vacuum pump interfaces with the Timing Device which drives the Injection Pump. Pretty easy to pull the vacuum pump and eliminate that as a contributor to what might be going on.

To accomplish that you need to remove the serpentine belt first, and in doing so you can verify that the belt or something it attaches to is not the source of your noise. Maybe something like the AC clutch of even the AC compressor is failing and making crazy noises.

I would be tempted to pull the vacuum pump first and see if its exploded and taken something out.. Either way you need to open it up and see whats grinding...

Is the engine cranking over at normal speed? If not an accessory could be seizing ad slowing the engine down enough not to start as well as be causing the noise.

cranks over at normal speed. I'll crack open a line and see if it squirts

The no start condition makes me think it's more than a failed vac pump. Grinding and no start, means the IP is not turning. Yes, removing the vac pump is needed to go further, so it's worth it to pull it and then have a helper crank while you look at the timing device.

Quickly separate the fuel line at the pre filter. If when cranking no fuel comes out then the injection pump is not turning. The lift pump is driven by the cam or crankshaft if you wish inside the injection pump.

That's a good idea. Pull the return line off and crank her over.

Why continue to crank the engine if there's a grinding noise???

Sixto

maybe it's just me but I don't understand how if something can be heard "grinding" repeating attempts to get the moving engine parts making more "grinding" noise is a very good strategy?

i'd be trying to understand what might have gone wrong between the last time it was running and it now not starting and making "grinding" noise.

A couple days ago the OP was commenting on the better mileage he was getting after a thermostat R&R, now after parking it something is "stripped out" in the timing/IP world? I'm not understanding how that could happen.
Another thing is the starter is on the driver's side of that engine, perhaps it's drive gear is not engaging or not disengaging and the "grinding" sound is emanating from that.

Something is turning and making a "grinding" noise, stop doing whatever your doing because more "grinding" is probably not helpful.

first thing i would do is release the serpentine belt tension and cjheck all the accessories for free turning, then the vac pump so you can eliminate that possibility, that allows a decent inspection of the chain, and the timing device. Then turn the engine over using the crank bolt(wire the Shut Off lever down!!!) that way you can get a feel if it's something connected to the crank, and you can get a look at the entire chain as it rotates around the timing device.

Then I'd pull the starter to verify it's not that, check its gear and the flex plate's ring gear for any damage or crazy wear. With everything external looked at and eliminated then with the vac pump off I would bump the starter just enough to see if the noise still existed with no vac pump and no accessories

If the noise still exists I'd check the flex plate through the opening in the oil pan used to access the bolts attaching it to the torque converter.

Then if all that checks out I'd start thinking about the IP and how that could be making noise.
