I just had an ACT clutch and ACT Streetlite flywheel installed on my '04. I went to pick my car up and it wouldn't start (the engine would crank, but not turnover). My mechanic said he just finished road testing it and everything was ok, but said that it was a little hard to start. We sat there for quite awhile trying to get it to turnover without any luck. After messing around with it for awhile, he plugged it in to his machine and determined that it may have to do with the crank sensor. We unplugged the crank sensor and it finally turned over. It was still a little difficult to turnover though. I got it home and bought a new sensor at the dealership. I installed the sensor and plugged it back in (it had been off because it was the only way of getting it to start). There was no improvement... I have since unplugged it and am supposed to go see another mechanic. As a sidenote: my VDC, Slip, and Service Engine Soon lights all came on. I reset the ECU with the ignition/gas pedal way and drove it around for a bit, but when I parked it and restarted it, the lights all came back on. You may be thinking "if it starts then just drive it without the sensor plugged in"... The problem with that is that it will not always start, it usually will but not always. I am beginning to wonder if the flywheel has something to do with it. This is driving me completely insane! Please, please provide any insight that you may have. Thanks!

 

Take it to an Infiniti dealer and do NOT tell them you installed anything. Let them tell you what's wrong.

 

I guess I will if I don't come up with any other results... I just kinda wanted to keep both of my arms and legs if you know what I mean.

 

Well I got some good news... I found out that my warranty is still in effect. What I'm wondering though, is if they determine the aftermarket flywheel to be the cause; am I responsible for all of labor costs incurred for diagnostics? I'm sure I would be responsible for the labor costs to fix it, but I'm just wondering about the cost of diagnostic.

 

Im not an expert on warranties. But I would assume that there are certain things that void a warranty. But you really have no choice but to wait it out and see what they say. Either way you need to know whats going on with your car.

Also, you dont have to tell them that this happened as soon as you put the flywheel in. You'd be telling on yourself. It really doesnt sound related.
