I just changed my clutch and everything now my car will not start. Before I did the work myself I took it to Mazda and they said they had to jump my neutral switch to get it to start at the dealership. Well now that im ready to start my car it dosent want to start. It seems like there is no compression. I turn the key the motor spins but wont start.

 

It could be related or it could be coincidence.
Read the the starting issues start here sticky found in the troubleshooting subforum and do a checklist. Failing still, report back what worked/ didn't work.

 

Did you fix the neutral switch issue? It didn't go away on its own


Could be flooded as well.....

 

I got the it to start cranking but it sounded like complete ****, it was really rough and it never fully started

 

Soo... have you done any troubleshooting?

Neutral switch is my first guess, as you mentioned there was an issue with that already. But you need to eliminate other possible causes as well. We can't help you if you just say "it wants to start but doesnt".

 

OK so here is where it all started. My throw out bearing basically exploded inside my transmission. As I rolled to a stop and was slowing down. My motor choked out really hard. Well I had it towed to Mazda they told me it was my clutch and what not. They also said that they were able to get my car to start by bypassing my neutral switch. Well now I have replaced my clutch, throw out bearing, pilot bearing and seal, and my slave cylinder. After I got all of it put back together my car will not fire. It spins but will not crank. After a while of checking my plugs, the battery and any possible wiring that could have been messed with it still will not crank. After fooling with it for a bit I got it to where it will try to crank but will not fully start. I'm going to check fuel pressure tomorrow. I've cleaned my plugs and my coils the battery is fine

 

I have also tried deflooding and jt didn't work. I also noticed that every time I try to get it to start I smoke out the garage

 

Oops

 

Definitely flooded as smoke is normal from an engine not starting but wanting to. You followed this procedure? Is your RX8 pre 2009?

 

I literally have the same exact problem and don’t know what to do ... any tips? I have an 04 Rx8
