Timing belt

If the car starts at all makes me think it's not the timing belt. It sounds to me like a fuel problem. Started fluid starts the car then runs out and the cylinders are not getting anything to ignite. I wonder why you feel the problem is the timing. ( when it starts with the starter fluid does it run like it should for those 30 seconds or is it jumping and sputtering all over the place until it quits?) I use to say when working on my cars in the backyard, "It's got to be the timing or its got to be the water pump". I learned whenever I thought the reason for a problem I was having "had to be this or that" it wasn't. Issues with timing belts are either they are adjusted correctly or not. If not the car may start but does not run smooth like it should. Replacing a timing belt is more than just slapping on a new one. Even a belt that the adjustment is off just a fraction will cause issues. Anyway good luck and let me know how you make out.
