Sr20det no spark or fuel

[Funtakie]

Hey guys need a little help, I reasently ran into a problem with my Sr not wanting to start, I have checked every possible thing I could think of and can not figure it out.

I figured it might be the Cas so I checked the signal wire for voltage, and got 5v, getting the 12v on power wire, however when I plug it into the cas and spin by hand I get no signal, I already tried another cas and same prob

Anyone get any ideas of what it might be?

As far as spark goes, which ecu do you have? I know I have a J4 ecu with a blacktop harness which caused some problems at first.

Ya I have the same setup, been running it like that for years, then I decide to upgrade the turbo and change to a blow through maf setup which worked great till my hose from my wastgate popped off and I blew a cup right by the maf causing the wires to short and fry the ecu, so I bought a new ecu same part no and replaced the burnt wires now no spark or fuel

Update I tore the wire harness back out of the car and found that one of my ecu grounds had pulled pulled out so I fixed it and will be throwing it back into the car today, hopefully this fixes my problem
