Motor won't run.

I have EFI issue.
Motor run for about 2-3 seconds then stops.
Keep cranking no go.
Then come back later motor run for about 2-3 seconds then stops keep cranking no go.
Have fuel pressure 44psi at the injector which all have been ultra sonic cleaned.
Have Spark.
 
Borrowed and change dizzy and ECU to see if any change nope same problem.
 
Does the engine start on the cold start injector only and then change over to the main injector as it warms up?
 
Checking the EFI Manuel there is a Start injector time switch.
 
Does this control the injectors when the main injectors come on or just switches off the cold start injector? I thought the motor would use the main injector with the cold start injector at same time on cold starts and then turn it off with the timer.
 
Need help
Been pulling out my hair over this problem. I feel like putting a bomb under it.
 
 
 

No, it like it's not getting fuel. I squirted some fuel into the manifold it ran longer. I think injectors are not getting a signal to squirt fuel. This is on my Red 92 Hardtop I have with standard ECU etc. I sold the Black Mr2 Rob.

EssDub
Circuit Opening Relay.

Does this not control the fuel pump? There is fuel pressure.

I have taken off solenoid resistor and checked it out and it's out off it specifications. Maybe this is the problem.

News update on my progress, retested Solenoid Resistor with an omhs meter on the right setting and it in spec and 
Tested on Carmikeys car and it ran for 15min. So it's not my Solenoid Resistor. My injector are not giving the engine fuel. I got a syringe and squirted some fuel into the intake it ran until ran out. I tested the dizzy it gives a voltage when spun so the ECU should get a signal, Maybe it's my ECU or faulty wires to or from the ECU. It not a  fuel Resistor or Circuit Opening Relay all tested on a mates cars and it ran fine. I will test the ECU on my mate car tomorrow, I hope before he sells it.
 
Does anybody have some insight on this problem?

Having thought about it a little more, I had a few more ideas (assuming the issue is fuel related):

• Buy/borrow injector 'noid lights' to test & confirm that injectors are getting the signal to fire.
• Fuel pressure does not necessarily guarantee fuel flow - it may be worth checking your fuel pump & filter if you have spares on hand.

Good luck!

Have you checked if the ecu will give any fault codes?
Agree with the person above you really need injector noid lights to check if the main injectors are even firing.
The ECU will provide a signal to the injectors to fire based on a number of different items in my understanding. I would disconnect coolant temp sensor, and also check earth for things like ignitor etc and body earths. The ECU will rely on a good earth from ignitor and other things to send the signal to fire injectors. Hence why you have spark but no fuel supply.. Just a theory based on **** that's happened to me in the past

In the first post you said you had tried another ecu but lower down you say you are looking for one to test with?
 
The ecu pictured is a late gen 2 ecu. Shouldn't be too hard to locate one if you want to swap it out.
 
Take the lid of the ecu and look for any damaged components inside like capacitors.
 
It's already been mentioned but have you confirmed that the circuit opening relay is functioning correctly? Sounds to me like this could be the problem if it runs for a few seconds.
