Having problems with your 1993 Cadillac DeVille ?

My 93 Cadi Devile will not start after having a new cathlytic converter installed due to the stock one going out on me on the freeway. The engine lost power and shut down and would not start back up. Took it to a shop and they did a diagnostic and said there was some how 50lbs of fuel pressure at the fule rail and there is spark going to the plugs and can't figure out why the engine won't start. They then told me after further checking that the timing is retarded or has jumped and is the reason

Thats kind of weird how you would have a cat failure and then as soon as it was replaced, your timing is off.. It doesn't make any sense, actually. If you can give some more details about this problem, I'd like to help more. (For example: when you turn the key, does it crank? If it cranks, do you hear any abnormalities in the revolutions? Etc)

To answer your questions: It is a pain in the neck to change the timing chain and gear. Its a lot of work. Even if you have air tools, you're still looking at several hours of experienced labor, just to get to the chain. Is it worth it? Thats a personal question that you must figure out, based on sentimentality, finances, etc.
You dont mentio if you have the northstar motor it has three chains.its probably your computer.
