The engine will start and keep running for a few seconds. As soon as I give it some gas it dies.

I checked for codes, but no codes.

I has emissions removed and I rechecked vacuum lines and good.

Any ideas would be great!

Thanks!

 

Mass air flow or Vane Air Flow Sensor Connected? TPS Connected? Ect...?

Can it idle without gas? Sounds like a giant vacuum leak making it run way too lean.

 

Find the Circuit Opening relay, pic provided, located to the right of the steering column under the dash and jumper a wire from the solid Black wire to the solid Brown wire and try to start the car and see if it continues to run properly. Also, check for voltage on the Blue wire in the same relay w/key to on when the two wires I mentioned are jumpered. If voltage is not present then the relay is damaged.

 

test the bac valve

 

I have checked them. If weren't connected I should got a code for it.

I will give it a test tomorrow. Never heard about this. Did you have a similar problem?

I can hear it clicking when key is turned on

 

Circuit Opening relay controls the voltage to the fuel pump. When the car is initially started the AFM does not play a role in dictating whether or not the fuel pump recieves voltage until the engine climbs to 500 RPM and above, which at that point the AFM takes over as far as providing voltage to the pump. And I do not have this problem but have helped others diagnose a similar problem but the fact exists that your problem could be something totally unrelated.

 

did you have your injectors off,or take them Off to do the emission delete?
My car did the same thing and it was Switched injector wiring.

 

Oh, I see. I do have a fuel cut switch for my fuel pump. I had to rewire my pump because of the old wiring.

Honestly, not sure. The previous owner did the emission delete during the rebuild of the jspec motor.

 

Your fuel cut switch might possibly be the problem then. Try what I suggested and if that doesn't help you might want to temporarily remove the switch you installed and see how that goes.

 

Will do, I will test it out later today.

 

I had it unplugged when I did the rewire for the fuel pump. I test it out, jumped the wire and test the blue wire for voltage. The blue doesnt get voltage.

 

With the two wires jumpered the key would need to be "on" for it to have voltage and the wire jumpered to the Brown wire is "solid Black" and not Black/White or Black/Red.

If you jumpered the proper wires and the Blue wire doesn't have voltage w/key to on then check the Black/White wire for voltage w/key to on. If it doesn't have voltage w/key to on then check the 15 amp "engine fuse" in the interior fuse box.
