injection problem..
 

Looking for a little help on this one.. 85 911 carrera turbo was brought into my shop with a no start. after some checking ive found no injector pulse. it has spark fuel pump will run.. Ive checked aldata pinnouts on computer all seem ok. checked crank signal.. has pulse. Now I need to know what this aftermarket fuel injection box is and if it could be the problem has the name " NEUTRONICS" lamda computer.. says for use with bosch fuel injection and is wired int computer harness under seat.. anyone familier with this? thanks in advance.......Mark..
