Just checked power to ECU, and it lights up like a Christmas tree...definitely power to ECU.

Do you still think it's my coil when I'm not getting a pulse signal when cranking,

did u get a new one ? and did u check your EFI RELAY its your main relay and your ignitor might be bad the only other this i could think of is your timing is off or your ecu is bad call tweak today and talk to him about it he might tell u to send the whole harness and ecu him because theres one wire and iif its lose nothin will work its purple pink or brown or black comin from the efi relay and goes in to the euc trace your wires from the coil to the ecu make sure they are lighting up tweak will fix your harness for free if its messed just send it back to him but i would tell him to check your ecu to if you got a new coil and still nothin it has to be your ignitor or your wires are wrong somewhere or your ecu or a relay is bad ............................................................
................. is your car turning over ?

yes, my car cranks very strong, and i have two igniters, i have tried both....nothing, had a friend check relays when turn key on, and both EFI and ST relay click, but even if my timing is off, wouldnt i still see a spark??

Well,'just finished installing new coil.....tried cranking again n nothin......this reappoint SUCKS!!

yes you would see a spark even if the timing is off umm man the only thing i could think off is the ecu or tweaksss wires but i really dont think its the wires but u never know how do u know its not e=gettin a spark did u stick a screw driver in there and let it light u up lol i kno it sound crazy but thats what i do lol call tweak if i was u i would send him my ecu and the wires let him go over it and make sure its good there find the ground to the ecu like u did the power see if your ecu is getting ground i think u are having a ground problem if i was near u i kno i could fix your problem but not being around the car is kind of hard lol i know how to make a car start when its not getting a spark but like i said im not near u so lol i have to go off your info does all your dash lights come on then u turn the key i kno this sound crazy but sometimes these cars get a short mine had this problem the check engine light wont come on when u turn the key that means some where those wires i was tellin u about has a short your car will turn over but wont start its a purple wire a pink wire and the other one is either white black or brown i cant remember but we had to e run that wire because it was trippin i know the prolem u are having because my car use to do it
