can any one help me my 300zx after a major starting prob which iv solved, tends to take 3 turns on key to start even with that i have to give gas for it the revs to get up and stabaliz, it never use to its always been first key starter, this has only come on after the other starting prob which made the car totly a non starter,it turned out that the ign coil relay wasnt getting the earth from the ecu to trigger the coil,iv done a temp fix of direct earth from body that way the car starts, im not sure if its the ecu faulty or a broken wire from ecu to coil, also the other problem is that the car idles fine after the rough start but soon as i take it on road and boot it it just doesnt go, it goes then is just pulls back no power at all, but low speeds its fine, my dump valves wosh what can this be?? tnx

first of all try a ptu then check boost leaks etc and run through all the basic checks and go from there !
