Hei module /injectors

Post by dnw3576 » Fri May 08, 2020 3:18 pm

Hi members, I am having an issue getting my firebird started, I have an 83 daytona 500 firebird with the 305 lu5 crossfire injection, s code, been trying to track down the issue that is preventing the engine from firing to life, got fuel to both injectors but no squirt , got spark, according to the manual the problem should be down to bad hei module, is there any way to verify the module is broken? , tested pin 2 on the ecu to dizzy (pulse reference) no short or cut, is there any thing else other than the module that can stop the injectors firing? Also at the rear of the engine I got a black square connector labelled wire 2 on one side and wire 3 on the other side, off the connector is a black wire with a loop terminal, looks like a ground, is it?, many thanks and best wishes for your time to respond
