300zx TT cannot get it to start correctly, Help before it bursts into flames!!!!

I will try and explain this problem and everything I have tried to fix it.

1. The car will not start but turns over.

2. Occasionally between starting attempts the car makes a cough as if its going to start then continually turns over with nothing.

3. Fuel pressure, Compression, Spark, Injectors, Airflow meter, Ignition Amplifier all changed and fault remained.

 

These next two point may enlighten someone to recognize this problem.

 

4. I remove the intake pipes from the inter cooler to the throttle flaps and spray some easy start into either of the flaps then attempt to start it the car starts purring perfectly and runs with no problem obviously until the easy start burns off.

5. If I block both intakes off completely after spraying a little easy start into the plenum and I take the throttle position sensor off and turn it fully to simulate full throttle then start the car it will run at 1500 rpm perfectly and until I switch it off...?????

 

I hope someone can shed some light on this problem

 

Many Thanks in advance

Ellodave thanks for the offer for Wednesday, im a little pushed myself for Wednesday, any other days in mind?? thanks for the offer...

ALso I do have a pressure regulator fitted its the unit with yellow pipes on and I get correct fuel pressure reading on the gauge, if I block the return to tank obviously the pressure goes off the scale and the car tries a lot harder bit obviously it would with the extra fuel being delivered.

I have an alternative option, I have a LWB auto with a perfectly good engine I bought for spares, an engine transplant might be called for. Does and auto engine in a manual car make any difference?? because this problem engine came from an auto too

Hay sorry been flat out over the last couple of days. Maybe one day next week if your about?
