Hi, any help with the issue will be extremely appreciated. I have a 97 Integra GSR with a T3/T4, 650inj, and s300 tuned by inline. The car drives/boosts fine, but when I turn it off and let it sit for a couple minutes it wont start. It'll crank fine, and if I wait for it to cool it'll start and run fine again. Sometimes just sitting in the sun for too long and the car wont start. Just looking at some values, inj. duty cycle is at 0% during failure. I definitely have spark but cannot hear/feel injector(with stethoscope) operation. Going to try to borrow some inj. diodes to test ecm signal, any other ideas or advise? BTW, fuel pump always primes with key on, main fuel relay was swapped just in case.
