no start problem
 

at the shop that i work wit we are having a problem with a 93 mazda rx7 with a greddy t78 turbo set up, we are getting no pulse from the injectors, we have changed the crank sensors and the igniter, the engine cranks over and there is spark, the injectors are spraying but there is no pulse to them, the compression in the engine is good cuz it was tested, is there any other reason that this engine would not be starting, any information is usefull and apriciated so if anybody has any ideas please let me know, my sn is j2ntense4ya and my email is rx7bout@yahoo.com so please get bak to me asap

EGI fuse/relay?

what do you mean they are spraying but not getting a pulse. how does that work? are they getting power? how are you checking the injector driver signal?

im checking pulse wit a noid light

ok so pull the noid light and see which is missing the power side or the ground signal from the ecu...
