[P_856]

My friend has a 93 civic (ex d16 vtec) and while she was driving it stalled on her she pulled over and the car wont start. Cranks but wont start.

I check the gas and and fuel pump and its fine.
Battery is fine and i even tried to jump start it with my car.
But for some reason there's no spark, whats so ever!
So i though it was the coil/igntior since hers looked kinda old bought a new one and replaced it still no spark. (spark plugs are 2 weeks old)
So i replaced the distributor with a new/reman one still no spark.
Cap and rotor looked good so i didnt replace those.
Checked all the wires and fuses and etc and everything is still good.
Opened the ecu up and everything looked good.
Only thing that i found was odd was the - and + terminals of the coil both had power when i used my test light.
I was reading online and it said something about the relay from the ecu and the map sensor not getting enough power i think it needs 5v im going to find my multi testers and test that tomorrow

any thoughts on what else it could be this has me stumped?
