Thanks, I found that a couple of the plug wires were in the wrong orderon the distributor. Now it half way starts as long as I keep the key onstart, but if I let it go it dies down and stops with a burp up throughthe throttle body. This could be timing? The bolt on thedistributor clamp is so tight I don't think it was adjusted when thecap and rotor were put on. (I didn't do the tune up) Or can thesesensors really keep the car from starting? I looked at theplugs, they are brand new but were carbon fouled and when they sparkedthey had more of a yellow spark that went across to the side of theside electrode, not straight out from the tip. From reading other blogs it seems starting is a MAJOR problem for these 4.3 V6's, and no one has a ready solution. Not to mention that just getting in there to work on it is a royal pain. I do appreciate the help, I need this thing to run, it's my only transportation.

Re: Still won't start
In my experience, when a vehicle runs only with the key in the "spring loaded" start position, it has been a faulty ignition control module. which is in the distributor i believe. could produce the poor spark youre seeing.

Reminds me of when a friend of mine had a car with carbon tracks on the distributor cap. I wiped it clean and it worked perfectly. Are the plug cables going to the correct cylinders in the correct order? A hanes service manual actually put the wrong order down in a mustang manual.
I owned the SAME CAR. Love it except when the Distributor went south. You can not tell if the spark is good enough... you can have a Spark on the outside but the compression will require a much stronger spark.
If they put the Distributor in wrong, then you will have an issue.
IF the Timing Belt was moved, then you are going to be fighting this for a while. Best to Start from Scratch with a Good Mechanic and see where it leads you.
If you spray Ether into the Air Box, does the car start? No Start, you have a SPARK ISSUE. STARTS, you have a Fuel Deliver Issue
THE DISTRIBUTOR's are KNOWN to be defective,... Mine was intermittent but when I finally dropped the $225 on a distributor, all of my problems went away.
Did they cross the Spark Plug wires and that is causing your issue? Check the Firing Order.
You have problem with you timing or did you ever label all the high tension wire before you unplug it. it might be re arrange the firing sequence. 1342 firing order. And the timing position of the distributor were at original place.
If all you did was replace the distributor cap and now it won't start. Either the cap is the wrong one, or it is faulty, take it back to where you bought it and have it replaced for another one. Make sure it is the correct one for your model.
When you took the cap off, did you remove the rotor button also? If so did you remember to put it back, don't laugh it is a common mistake.
Something else to check is that all the plug wires are snug in the distributor cap. Test this by pushing down on the actual wires and not the caps. Some times they don't go in far enough.
A couple of other things to check in the cap is for 'tracking/arcing' you will see this by taking the cap off and looking inside it and if it is tracking you will see a what looks like a hairline crack, this is from the electrical charge arcing out.
Check the little carbon rod that sits in the top of the distributor cap make sure it springs in and out and isn't broken.
pull number one spark plug and put your pinky in the hole, rotate the engine with the starter solenoid and when u feel pressure at max u are near or at number one cylinder top dead center, bring the timing mark to 10 deg BTDC and then pull distributor and point the rotor to number one plug wire terminal.
I thing that the main problem turned out to be a bad ignition coil. On '93 Corollas, you can
remove the ignition coil without removing the distributor. (You only need to
remove the distributor cap and rotor.) you mention that u already replace couple of parts but i suggest to get the original part from Toyota spare part
