Please help me..car problem, Distributor Options

[94celicany]

My 1994 automatic celica is and always has been failing on me. i attempt to start the car and i hear the engine turn over for a second than it shuts off. My mechanic who is insanely hard to reach told me the distributor is bad. I just changed the distrubutor cap but it still does not work.
So now a few questions,

1. Do i need to replace my whole distributor?
2. If so, is this a hard tasks to achieve?
3. How much does a whole distributor kit for a 1994 celica cost?
4. If this is not the problem, any suggestions of what it could be?

Please, don't bash me or anything. My car and i are not getting along for the past 5 years. Any help would be awesome! Thanks all

Check to see if you have spark in each cylinders and see if there's any oil leaks into the distributor cap (gasket issue). Most likely will have to remove and install the whole thing. Roughly $30-$150 depending where you buy it from, local shops that reuses parts are cheap, but you get what you pay. Then you have the auto parts stores that will deduct a certain amount if you bring in your old distributor. Takes about two or three bolts that holds it down and twist it to come off.
