ok i have a 86 N/A with racing beat exhaust am having a bad start up issue every morning! i try to start the car and i takes forever then when i fires it does the accelereted warm up process and then dies, i try it agian and dies, i tried keeping the throttle pressed and it studders then dies! if i can get any help it would be great!

 

another thing is when the car is warm it starts fine, it's just when the car sits for a long time.

 

Water thermosensors plug is off.
