Hi everyone,

I'm having issues with my FC, it cranks, but it won't start... let me give you the details.

It's my daily, one of those weird NA FC's with GSL-SE style dizzy. Engine's streetported, and had DLIDFIS ignition, you can find details on my build here, in case you're interested.

Anyway, back to the issue at hand... today the car started, cold, and while it was warming up, all of a sudden revs went up by themselves to about 3500rpm for a second (not because of the accelerated warmup thingy), and the engine died.

Tried to start it again, and nothing... the engine cranks, but the the tach is all over the place, while you can clearly hear it's rotating at a constant pace -- check out the following video:


(btw... car doesn't start, what you hear at the end of the video is a car passing by)

You can even hear the buzzer go off for a sec... problems with the tach signal?

I know what a flooded engine sounds like, and this isn't flooded at all.

Would issues with the tach signal lead to the car not starting at all? Could this be caused by either a failing Trailing ignitor, or a failing Trailing coil?


Thanks in advance for your feedback!

 

check your cap and rotor first. then check all your ignitors. yes, the tach signal would come from the trailing

 

Checked the dizzy cap and rotor, they are perfect.

Still need to check the ignitors and coils.

Now, something I find weird... when I turn the key to the "ACC" position, sometimes the tach's needle goes up and bounced for a second or two...
