Hi guys need some advice on how to diagnose why my Z32 won't fire. I have replaced the crank angle sensor as it had no spark at all. Now it had spark but won't fire. I'm getting fuel to the engine but not sure if the injectors may now be the issue. Any suggestions would be appreciated. Thanks
How do you know you are getting fuel to the engine? If your injectors are the issue then you are not getting fuel to the engine 1. take out each coilpack 1 by 1 and hold it near a bolt. have some one start the car and you should see an arc. if all coilpacks arc then they are fine. 2. Do the same thing but with each spark plug in a coilpack. hold the spark plug against a bolt to ground it and check all 6 plugs get spark at the tip the same way you checked in 1. 3. Unplug all injector connectors. turn the car off and make 2 1 meter long wires. Solder the ends so they have a good tip to connect with the injector pins. put 1 of each 1 meter wires you made up on each battery terminal. Avoid touching the plenum with the wires and put each wire on a pin each on 1 of the injectors. you should hear them 'tick'. Do this on all injectors and if 1 or any injectors dont make a tick noise then they arent firing. 4. solder a wire to each terminal of a small bulb. Place a wire in each of the 2 pins in the injector connector. The bulb should light up when the connector gets its pulse signal. If a connector doesn't light the bulb then you have no signal to tell the injector to fire. Those 4 steps should rule out a spark or injector problem. If it's not either of those then you have to search deeper for your problem.
