Its possible that the pressure valve relay is bad, you can try that. I had to replace one last year because it was doing the thing your talking about. I hope this helps. Alvin

Start by checking fluid.If that is good it sounds like trans.is bad

yes! its the best time! and only time since the engine will be apart.

jack up the drivers side of the car, crawl under and look where the transmission bolts to the engine. you cant miss it :) it will have a big wire coming off of it ( power wire)

it seem to me that the park and dash light are on the same circuit, could be the light switch, or power to it

Fixing the clutch, I bet one of the lines had been leaking clutch fluid for quite a while. May top it off, and have a friend stomp down on the clutch to see if you can find the leak and repair it, then make sure to bleed your clutch back off. BTW, do you mean no compression as in the clutch has completely gone, or the engine has lost compression?

is there a tbelt or chain did you do comp test on cyls

its not hard at all. as long as your good with your hands. and know the basics of your rx7. other then that everything bolts in. you just need a turbo driveshaft for sure. or they sell a custom driveshaft on mazdatrix.com so you can keep your N/A differential.

I am assuming it's a standard. Your clutch and pressure plate are slipping. Check to see if the clutch can be adjusted , if not they have to be replaced

backfiring is a sign your running out of gas. You need to check fuel pressure to confirm. This is the first step. It could be another issue but without testing components its all just a guess

mmmm. familiar thing, get a compression test done, should read about 6-7bar of pressure, i had same thing when i got a second hand one, done test and one of the rotors pressure was down,

sounds like maybe your OEM fan clutch is wearing out and maybe also a stuck or bad thermostat!

maybe u should just give it to your cousin chris...

The Starter is most likely the problem. The solenoid in the Starter doesn't work so well when it's worn out and gets hot. That's why the solenoid works better when cold. Changing the Starter out should solve the problem.

You have a warped head,cracked head or blown head gasket.

I'm not very familiar with rotary engines but I'm pretty sure what you have is a gasket that needs to be replaced.
It is highly likely then that you are also burning it as well so don't run it until you change the gasket.
