so a couple weeks ago i started running into the problem with my car where it wouldnt turn on when i tunr the key so i figured it was the starter. then it started getting hard to pushstart as in it would hit 50-100rpm and i would bob the gas and it would barely cut on. know it is at the point were no matter how muhc i bob the gas it will not start after it hits 50-100 rpm. then lastnight i was driving down the road and i put my car in nuetral and it cut off and i was going about 30mph and when i put it in 3rd to pop the clutch it wouldnt start...... . then i let it sit for about 30min and it still wouldnt start after push starting the car.... does anyone have any ideas on what could be wrong with it .

Are you getting fuel,ignition,was the car smoking,whats your compression,fuel pressure. Have you checked any of these.

Start with the basics and work your way up from there. Verify and replace all vacuum hoses if necessary. Check your IACV, it might be dirty.

Make sure your fuel pressure is up to par and definitely verify your compression. All you need is fuel, spark, and enough compression to run a car, so something in there is missing or going bad.

i no it has spark cuz wen i push start the car and the key is turned it tries to start the car and i know there is fuel cuza wen i get it to around 50rpm i bob the gas up to 100 and normally i can bob it from 100 to 900 or soo and it will start idling fine and have no problems but i know there is a guy that lives somewere around me that told me he had some gaskets a couple months ago and when i asked him for my money back cuz he couldnt find them he told me if i bothered him he could cut 1 wire in my car and i wouldnt ever know what was wrong with it and it just started doing this like 2 weeks after...... i know my 3000gt would cut off on me going down the road when i put it in nuetral wehn my alternator was bad but idk if that is the problem with this or not and i dont have any machines to check the compression on the engine but if i can get someone to check it what should it be like 180 across all cylnders

there was no smoking or anything im pretty sure someone i know messed with it and broke it . becouse i was at walmart and i live literly 5min away and i was on my way home in my neighborhood and it just died,. there was no smmoking or anything i know i have a exhoust leak at my turbo to manifold but i dont think that is what did it becouse it is a small leake.

I'm pretty sure he's BS'ing but check your wiring harness. Just strip it down. I stripped mine like 3 times when I did my swap and I caught something twice. I mean it won't cost you anything to strip it down and check for all the wires.

Did you check and see if you are getting any codes to me it almost sounds like the ecu is not getting a signal from the CAS sensor
