Clutch problems please help

It seems like it does turn the engine the same way as before.

So, does your clutch system need bleeding .. ??

How about the clutch return spring ..... is it still in place .. ??

I only took off the 14mm I didn't disconnect any lines

Ok, then my money's on something else electrical. Are you absolutely certain you reconnected the ground wire? The black wire in the DIY pic that humfrz posted?

All the wires, for that matter?

I know you said you didn't mess with that encoder wheel but are you absolutely positive it is still installed properly?

Are you certain the crankshaft position sensor itself is not damaged? This is the most common issue with flywheel replacement that causes exactly the same symptoms you describe.

Yep, I'll go along with ol Ultramaroon, I'd bet it's something electrical.

I'd suggest you carefully check all ground wires and carefully plus check those connectors (make sure they are not plugged in backwards (tried to be at least)) by disconnecting them and re-connecting them.

Well, @MelvinKennyG ..... this old keyboard mechanic is going to have to turn in for the night.

Maybe ol Ultramaroon will hang in there ...... after all, he IS younger that I ....

Maybe in the morning, the morning keyboard mechanics will have some fresh ideas.

I checked all the wiring again and it all seems ok

hmmmm........let me think on that.

I reckon @Ultramaroon may have some more ideas when he gets home from work.

Meanwhile, who out there has some fresh thoughts ...... ??

@Tcoat is just laying around a motel room ..... maybe he has some insight ....

I'll ask another couple questions that may seem unrelated but trust me, they are.

1. Did you know to support the engine before you removed the transmission?

2. Was there anything at all about the job that did not go well? For instance, did the flywheel fit just fine, or did you have to force it?

[humfrz]

.........and another question:

Was the clutch and flywheel OEM or after market?

Really intrested to see where this goes. A buddy of mine did his cluch on his '13 FRS and everything was fine after install.

Just thinking out loud here.

If the engine is spinning over and it fails to fire, one or more of these conditions may exist:

* it's out of gas

* there is no compression

* both fuel pumps went bad at the same time

* all 4 coil packs/spark plugs when bad at once

* the ECU is not telling the engine to inject fuel and/or not to send spark

So, I'm figuring the ECU is not asking for fuel or spark.

Now, what is the "connection" between the flywheel/clutch/pressure plate/transmission and the ECU ..... ??

(I can't be much help, because that's over my pay grade ....)

I wouldnt be surprised if the clutch isnt making any or just barely not enough contact to fire up. Couldnt tell if OP said that the car clicks when he goes to start it or not.

Thanks, lizbrayan, for joining the ....think tank.....

Since the starter turns the flywheel and the flywheel is connected to the crankshaft ..... would it matter if the clutch was there at all ...... when it comes to the engine firing .... ??

As I recollect, the OP says the engine turns over but won't fire (is that correst, OP..??)

I think that the clutch might not be making contact how can I fix that?
