ka wont start

[s14fbs]

i had my built ka-t out for a rebuild due to fried rings and a bunch of other shit

i put the motor back in started up fine ran perfect no misses normal air fuel ect blah blah while letting the car idle for say about 20 min bleeding the coolant system the car dies i start it back up runs fine for about 15 more min then dies again and would not start

i checked spark its good
checked grounds there all clean and tight
all connectors plugged in
tested my fuel pressure have pressure

i check my fuel injectors pigtails with my noid light set and i have no fire going to the injectors
check all my resistors there all fine
so i buy a new harness and replace it still no start
replaced the dizzy still no signal
opened up the enaplthy tuned ecu and there are no burn marks in it or any sign of damage
i have checked the ecu pins and there all fine not bent good connections
there brand new rc injectors ect
i have tried to use a stock s14 ecu and that does not

so anybody with wireing experience have any ideas what it could be i have checked and replaced everything i could think of

its a
95 s14 ob1 with a s13 ob1 ka ecu

If your getting no signal to the plugs to the injectors then its some where between ecu and plugs. Ohm test the wire from ecu and plug see if there is a rating that's where I'd start

yeah im puzzled cause its the same thing with both harness

im going to test the ohm on the ecu injector pin tomorrow when i get a tester

Your not going to want to ohm test the ecu your gonna want to test for power coming from the pins. You might damage the ecu if you ohm the ecu

Ever find the problem?
