First thing you need t poo do is determine if it is a spark problem or a fuel or compression problem.pull a plug out hook it back up to a plug wire and touch the bottom of the spark plug to the block or a bolt.Then have someone try to start the car.if it sparks then it's most likely the fuel pump.to see if it is a fuel problem get some starting fluid and spray it into the intake manifold then try to start it make sure you have put the plug back in first.if it runs then stalls replace the fuel pump relay if it still doesn't start replace the fuel pump

Best to do a fuel pressure test, pump might be weak and dosent show up until it gets gets warm. Best to do the test after it quits again when pump is at its hottest. If you havent done it yet chg. fuel filter too.

Hi
Need to know alot more info here?
What happened prior to no start?
Does the engine actually turn over?
Does the engine fire on some cylinders or none at all?
Ancient Technicians proverb says an engine must have 3 things to run.
AIR, FUEL, SPARK, has it got all three (I doubt it)
Once confirmed move onto more Tech things like
Ignition timing, Valve timing, Air leaks, Crank angle sensors, Cam angle sensors, the list is endless.
Last but not least was / has the vehicle got the correct FUEL in it?

My tercel keeps ticking when I try to start it.. Could it be the starter??
Maybe the antitheft system. Read thru this link

I follow your story and found it very interesting. Looks like as the vehicle was driven decided to get relaxed. For what you done up to now you spent quite good amount of money with no results. Has at all passed from your mind whether all that cause by means of immobilizer activation or any fuel pump failure? The Knock Sensor want stop deadly the car. It causes misfiring,stalling etc.Hope this help, Good Luck.
