i had something like that happen but it was a easy fix one of the injector wires wasnt covered up very well andgrounded out and blew the i/e fuse but i doubt thats your problem

Okay so first off are all the grounds hooked up- tranny,thermostat etc.Second is there power at the main relay located by your feet on drivers side?You have voltage in the solenoid wire at the starter when cranking?You try a different ecu or one that is known good.You need to start a list a work through it step by step.What did you do to "hotwire it".More info is needed.What is currently going on you have no spark but you have fuel?Are you positive your injectors are opening you need some test lights or noid lights available at a parts store they plug in the injector harness and light up when there is a signal for the injector.

all grounds good been over them to many times took out the main relay followed the test steps clicked for all. i know the injector did work for alittle while cuase i smelt teh gas(exhuast end mid car i took it of to weld) had spark stuck the screw drive in the plug and crank spark jump it was strong too. heard the pump prime. it was coughing and what not so we figure we fouled the plugs trying to start it with wd40 .but now im back to only my starter working and no codes,i dont have a diff ecu and dont really got another 50 bux to buy one

i test the relay clicks for all(out of car 9vbat)
in car no click for any key movement but have power at one wire only thing that gets power after relay is starter. i have 3 realys can they all be bad for real,one came in the car and i drove it home
