:crying: Hey guys
This one stumps me. I have an 87 rx7 and when I bring it all the way up to temperature.
I turn the motor off it will immediately start back up. When it sits for a couple of hours
It will not start until it is completely cool

Fuel pressure has been tested /volume/ pressure
It is getting spark during the period that it does not start
The spark plugs are not wet as though it is flooded

Any suggestions

How is the fuel pressure/volume during no start ?
Is it a strong spark, bluish white, or a weak spark, orangish, during no start ?

Just some thoughts

Pressure directly to pump 57 lbs
Circulating pressure 37

Here are the fuel pressure readings with the fuel pump connector jumpered:

1986-1989 ( Except Turbo) 64-85.3 psi

1986-1989 w/Turbo 49.8-71.1

To verify fuel pressure is to low to fire injector you could spray starting fluid into the air intake during no start.

Hmmm, do you have a stand alone or stock Ecu?

You need to get it compression tested as not starting when its up to temp indicates low compression.
