I have an 86 Rx7, and it turns over but will not start. I've checked most of the things I can think to, I've got spark, fuel, and good compression. I've gone through a few pages of trouble shooting, but still haven't figured out the problem. The car was running fantastic, then the next morning, it just wouldn't start. Please, if you have any suggestions or ideas, I would really appreciate any help I can get.

 

Tried the deflood procedure yet? Pull the green 40A EGI fuse from under the hood, crank the engine for a couple seconds, replace fuse & try to start it. For badly flooded engines, 2 spark plugs can be removed when cranking w/out the EGI fuse.

 

I have tried the deflood procedure, but with no change. I will try this again though, because I didn't take any of the plugs out. Thank you.

 

I went through the deflooding procedure, and it still doesn't start. I've checked numerous things, and am now pondering the timing. I'm unsure of how to work that out though, because the car wont run....

 

Take a look through this thread: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/rad-exploded-now-wont-start-o-rings-compression-fine-s5-na-883779/. The OP tested just about everything related to starting to track the problem down. This was for an S5 NA though, so some things will be different. The S4 FSM will give you the equivalent tests.

 

Thanks a bunch. I've looked through a lot of that, and have done quite a bit of testing, I'm still coming up empty handed. Right before my car went down, it got bumped on the front end by one of my neighbors, so over the weekend i'm going to go thru it again and start looking for anything loose or unplugged also.
