Will not start

Been too 2 different mechanics so far with no luck. Engine will turn over but will not start. First mechanic said it was the ingition Igniter, replaced it with no luck, 2nd mechanic said it was the ECU, replaced it with 2 different ECU's (used) with no luck. Sometimes the car will start after sitting a couple of days, when it does want to start it runs real rough (cant even drive it) and after idleing for about 5 minutes it smooths out and runs good. Checked it for spark, no spark. When the key is turned on I dont hear the fuel pump. I disconnected the fuel line from the filter and I get fuel only while cranking the car over. Vehicle was at the dealership for almost 2 weeks and they dont have a clue. Please. Can you help me?
Thanks

Like I posted in my question. There is no spark. Changed out the Igniter, coil packs and ECU. Still no spark.

Its called the igniter, not a coil from what I'm told you either have one or the other, my car has the igniter, its mounted on the firewall. Its also distributorless. Thanks for your reply.

Last running, had to pump accelerator to keep running. Replaced fuel filter & then fuel pump.
Have fuel to filter
Have spark
compression 1-4, 80 / 80 / 60 / 70
checked timing, crank at TDC compression, cams marked in time.
At first turn over, sounds like 1 or more cylinders try to fire. Then motor just spins over by starter.
I am not familiar with EFI systems

This car has sat over a year, I got too frustrated with it.
Today put a new battery in it, checked everything as before.
I cranked it over continuously, while pumping the accelerator A LOT.
Eventually the motor fired weakly, then began to gain power. I was able to maintain revs and even control rpm as long as I maintained revs well above idle.
As I let off the accelerator, the power died and the motor eventually stalled. I can fire it up by pumping the accel furiously, but the motor will respond only to accelerator way above idle.
What to check / test next?

Hi I have a95 Toyota tercel dx, when I turn the key it sometimes starts everyother time you turn key it does nothing no sound or even a click but if you push in clutch turn key it starts right up no problems. Next time I stop same thing. What could I check for? And does this car have a relay switch? Thanks for any help suzieq

Hi thanks how would a thanks suzieqgal like me check that?

Sorry, how would a gal like me check for the switch is bad or good? Any help? Please thank you so much.

I have a 1995 toyota tercel and for two years it hasnt been use. When it was used I never had any problems but because it has been sitting in my drive way not touched or ran in two years, im of course having trouble starting it now, ive changed the oil and put new gas in it but I dont know much about cars, im not sure where to start fixing the problem it will crank up but wont start. Plz help!

Would you no where I can find a diagram for the switch I want to see if I can change it myself? Thanks and bless you for your help. Suzieq
