Question -
I have a 91 eclipse 1.8l auto. It has power to the distributor but no spark top the plugs, I bought a haynes Manual and can't figure out what the heck it's talking about... I changed the distributor and it made no difference, would the next logical step be the computer?
Answer -
Mark,
A problem with your computer is definitely a possibility.  Read this article for further information:

If your ECU is malfunctioning, it can cause the problems you're experiencing.  Your Haynes manual will show you where your ECU is located and how to remove it.
Good luck!

How do I know what computer to get since the cover is not on the one in the car...

Mark,
If you're looking to purchase another ECU, you can contact this group:

You can give them your car's info (engine, transmission, accessories, etc.) and they can match the ECU.  They may even just need your VIN to determine the right ECU for you.
Good luck!

Once more... I have changed the computer and the distributor what else could cause me not to have any fire? I have voltage going into the dist. but I have no fire. I ahve tried 3 different dist, caps and rotors and 2 ecm's and no luck. Any more suggestions?

Mark,
Sometimes when a distributor is replaced, the points don't line up quite right.  So, the spark and the fuel injector may be out of synch.  Hence, your car will not start.  You may just need to set the rotor in the distributor to a different position until it's correctly firing in the correct sequence.

If you have a voltmeter, check your spark plug wires.  They should only have 1-2 ohms of resistance.  And if your spark plugs look abnormally worn, you may want to replace them.  
Good luck!

Once more, is there a crank angle sensor that could be causing my problem? I replaced dist, ecm, plugs, wires, dist cap, and rotor. I also checked all fuses and links, bought a new ignition switch and battery. Still no fire.

Answer
Mark,
A misaligned or malfunctioning crank angle sensor can cause this problem.  If the ECU detects the crankshaft is not on the correct cycle (or angle), it can prevent the car from starting to avoid ruiing components in the head. Sometimes that sensor can detect the wrong angle due to a slipped timing belt.  If the timing belt has slipped enough teeth, the crank angle sensor could prevent the engine from firing.  It's worth checking out since you've already put so much effort into getting your car running.
Good luck!
