2001 mitsubishi Diamante - starting / timing issue

Hello everyone, kinda new here so just want to let you guys know in advance that any help will be really appreciated and if there is anything i can help anyone else with i will do what i can.
I have a 2001 Mitsubishi Diamante, the thing just wont start. I think that the timing may have skipped since i do have good spark, fuel is getting to the engine but there is no compression at all, i measured it and the gauge did not move at all ( the gauge was also tested on another vehicle to make sure it is working).
I did take the timing cover off and the belt is still in tact, looks old but on there, one thing that i did notice is that one of the serpentine belts is missing, not sure if that would have anything to do with the problem.
So i guess my questions are:
Could a timing belt that skipped cause no start and no compression problem?
Is there anything else i should check before i try to put a new belt on there?
Any advice will be very appreciated !

Trouble likely: Only Mitsu engine listed that is NOT an interference engine is the engine 2.4L SOHC. If it jumped just a couple teeth there's a chance otherwise it's engine damage that can be bent valves or more,

My information says that all Mitz engine except the 3.0 SOHC 12valve is an interference engine. The 3.5 in this car definitely is interference.
Since you mentioned the serp belt being off, I would double check the crank sensor to see if it was damaged by the belt coming off.

Unfortunately the sensor is good, dear god all the stuff i had to go through to get to that thing. So i guess only thing left is to get someone to check the timing. Unless there is an easy way for me to check it my self.

Don't even crank it anymore as you might be OK in that it didn't just break. Not sure how many teeth would give no compression before damage. I don't know why this regular accessory belt gave out at the same time unless in was one for A/C only and you didn't notice till now and that's a different issue. Before you go too nuts find out while that one is off if the pulleys turn or if one threw a fit.
If there's a goblin that cause both at once I can't think of it but possible.
Hammer - I got that info from Lamb's Auto site and if incorrect I'm ticked. Just checked again and it wasn't an eyesight problem on my part - that's what it said.
Site did NOT list change miles for this or any Mitsubishi so perhaps I need a better site for that info.
As said - there's a chance if timing belt is still on that no damage has happened mechanically to the engine. About the only ways I can think of to know is either a scope where you can look thru a spark plug hole or take the head(s) off,

The belt that gave out is actually power steering. All pulleys seem fine, whenever i did crank it i did notice movement through the oil cap which of course doesn't have to mean that everything is fine but oh well. At this point i think i will go ahead and get a new belt on there, get it timed right and cross my fingers, whatever happens.
Thank you guys so much, this is a great place to get some help. I will let you know how it turns out.

Don't try to change the timing using the old belt. If it jumped time, even by one tooth, then the belt is junk. If you go deep enough to move the belt, then by all means, replace it.

I already got a new one it was only $27. It would be kinda crazy to reuse an old timing belt regardless of the price, so i agree with you.
