I have a 1988 Mazda Rx-7 non-turbo and not all the time but every now and then when i go to start it it cranks but wont start. Is the engine flooding or is it something else?


I always start my '88 RX7 with a 2 start procedure. First start is short about 3 engine revs...second time it always starts.
If I don't do that it cranks & cranks.....try it.

1987 RX7 Turbo cranks but does not starts. Was not getting fuel to system so, I jumped pump and works ok but, still not starting. Power in coils, ignition and pump OK. ?????? Need the car ASAP! Any HELP...


I use to run my own switch for the fuel pump. Leave the power off to the pump for about 10 mins. Then power it up then start engine. If this doesn't work use a little starting fluid. If that doesn't start the engine check to make sure you are getting spark to the plug. If you are check the compression.

I have a 1989 mazda rx7 convertible automatic with the 13b rotary engine and im going to swap the engine and tranny for the 13b turbo engine and manual tranny,and also have ecu.is it hard to swap and how.


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.

Suddenly started running rough like on one rotor as i was driving. heat gauge come on but was not overheating,no oil loss oil pressure fine spark fine no smoke, its a 1990 rx7 series5 13b turbo


ALL RX Engines are a 6cylinder as they have 2 triangle rotors with apex seals and 4 spark plugs but both rotors in both cylinders fire 3 times each and you have 2 rotors 2x3=6 ..Now if you are running on 1 bank which is 1 rotor then the other rotor isent working due to either the RED rubber seal band on either the front or centre housing OR the centre housing or the rear housing, has a leak and it must either be water or oil UNLESS its in the inlet manifold gasket leaking air in or the plugs on that rotor front or back , if the plug gap has closed up or oiled up .as there isent anything else i can think of .which could cause it.
Ihave built a few of these RX motors and they are without a turbo a lovely engine and go like s--- of a shovel get it going and dont get booked for speeding.. Let me know how you get on Ron

Leakin anitfeeze down by the spark plugs why?


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.
