Hello,

My dad purchased a 1993 Mazda Rx7 last summer and have had nothing but bad luck with it. It will start fine when it's cold then when it warms up it floods out, so he was advised that it was computer trouble and that he needed a new computer, so he put one in......still floods. So next he's told the motor is bad, the dealership tested it and said he needed a new motor. He takes it to a second dealership, they come back with the same thing...need a new motor. He replaced the motor....it's still doing the same thing and the mechanics at the dealership don't know whats causing it to keep flooding . Any suggestions??

Thanks Bill

 

isn't that a problem with the injectors? How exactly did they determine that the motor was shot? did they do a compression test? hopefully they didn't replace the motor for nothing.

 

I'm with Snook. Have the injectors cleaned and flowed at a place like RC Engineering or Marren Motorsports.

The computer was never the problem. Leaky injectors can cause flooding, this flooding can constantly wash the oil off the rotor housing, leading to low compression, which in turn leads to harder starts and more flooding. So the motor might have been bad like they diagnosed, OR the gas washed all the oil off the rotor housing and gave a false low compression reading.

You have learned an important RX-7 lesson: never take your car to the dealership for work.

Always have a rotary mechanic do it, or just do it yourself.

 

Thanks for the suggestions, I printed your replys for him so he is going to take the info to the mechanic and hopefully this will solve the propblem........thanks again!

 

Ok, My Dad called today and said they cleaned the fuel injecters and checked for leakage, they said the injecters were fine, they also did a compression test on the fuel pump to see if that might be the trouble I guess that turned out to be ok as well, if anyone has any other suggestions it would be be appreciated!!

Thanks

 

I think you should start a new thread and try again because someone on the forum has to know what else it could be.

For now when you think it is going to flood because it's warm floor the gas all the way down while cranking it over. This should stop it from flooding. BTW this is what I have to do to get my car with no compression to start.

If nobody gives you an answer here soon you really need to take the car to a rotary specialist. Isn't there someone anywhere near where you live? They will figure out the problem immediately. There is a reason why they are expensive...because nobody else knows their *** from a rotary engine.

I really hope you get this fixed I know it sucks

 

It sure does!! Thanks for your input I appreciate it! I'll try a new thread

 

Recommend you contact Dave at KD Rotary.... here's a link to his web site.... drop him an e-mail or give a call.... He's a good guy and knows his ****!! http://www.kdrotary.com/ He may be able to assist you with a long distance diagnosis or even suggest a rotary specialist in your area.

Don't even go to a Mazda Dealership.. those mechanics, and I use the term losely don't know the square root of **** about rotary's. You'll only "walk" away fruastrated

 

PM me if you need more info
