Dadaluma Posted February 6, 2010 Share Posted February 6, 2010 Hello everybody I am currently trying to put a vg30 in my 72. I have the engine from the z31 out of the car with harness attached, the engine ran great before i pulled it out of the car. Now even with everything attahed the engine cranks, fuel pump primes, engine rotates but will not fire. I am just looking for suggestions, as i have been chewcking wires for 6 hours with no results. does anybody have any suggestions? -cheers James Quote Link to comment Share on other sites More sharing options...
Mikez31ss Posted February 6, 2010 Share Posted February 6, 2010 First suggestion is DL a factory service manual. Second is check the power transistor circuit. Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted February 6, 2010 Author Share Posted February 6, 2010 ok thanks i will try that, sometimes i think it is best to step back think about it. power transistor, is that near the coil? Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted February 6, 2010 Author Share Posted February 6, 2010 nevermind I found it, does this increase the voltage of the spark?. one more question if i have been cranking the engine over and over without it firing should it smell like gas?(no exhaust equiped) because it doesnt could that mean injectors arent firing?

Mikez31ss Posted February 6, 2010 Share Posted February 6, 2010 Yes it is and your motor requires it to be able to run. I'll look through my shiro and 85t pics to see if I can find a good shot of one. Oops forgot I had coil packs on the shiro but you can just see it in this pic. And you can dl just about any Z FSM here: http://www.xenonz31.com/reference.html Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted February 6, 2010 Author Share Posted February 6, 2010 thanks for all the info I did find an fsm. I am going to pull a plug and see if it is firing there. Quote Link to comment Share on other sites More sharing options...
