1988 Mazda RX7 10th Anniversary from North America - Comments

I just bought it for 1100 and it needed tires and a battery and a new steering wheel which working at an auto parts store is fairly simple stuff. I know it needs a tune up normal stuff for a car that has been sitting. But I have a severe case of my car flooding which I guess is fairly common for the Gen. 2 RX-7 but it is so bad I can only drive the car once a day, and god for bid I should have to turn it off because it will take a whole day before it even thinks about starting again. it had a major coolant leak which I fixed what else should I do? I am getting ready to tow it to the scrap yard I can't afford a new motor and I am getting sick of it.

Your problem is leaking fuel injectors. My 87' had the same problem. It's a pretty easy fix if you have the right tools. And since you said you work at an auto parts store it should be easy finding the parts. Good luck.

The problem is flooding.

Try pulling the fuse for the injectors.

Its located under the hood.

Turn the engine over for a few seconds with the fuse out to clear the gas out.

Put the fuse back in and it should fire right up.

I have also had flooding problems with my 2nd Gen. Mine is due to short distance drives where the engine is not able to warm up to normal temperatures. I agree that your injectors sound leaky. Another good fix for this is installing a simply switch under the left side of your dash that cuts the fuel pump line. It is pretty simple to do and also acts as a theft deterrent system. With this switch, I just flip it when I'm about to turn my car off and it dies from the lack of fuel. This also insured that no flooding can possibly take place and relieves the pressure in the fuel lines. In my friends 91 rx7 if he starts the car with the gas pedal all the way down it cuts off the fuel pump allowing the engine to un-flood. I have heard this is only on 89 and newer, but it is not confirmed, you can give that a shot though. Best of luck...

All these comments are good, but there is one problem with them they do not in my opinion pertain to you. You say you drive it and are afraid to shut it off so that rules out the "typical flooding" problem pulling out the fuse may work from time to time, but in your situation I believe it will not fix or even work. The only way to get your car running when it does not want to is to pull start (pain in the ass) it well you will only beable to do that if it is a manual. Leaky injectors could be the problem or even a bad injector. Injectors may work cold, but not when hot. With my experience it is one of five things or a combination of all three.

1st: Check the injectors (refer to the workshop manual) Leaks, operation and Ohms.

2nd: Leaky intake, or vacuum lines way to rule this out is it should make car run rough when hot, but never hurts to check

3rd: Fuel pump and filter (check pressure to the injectors)

4th: Faulty coil or plugs

5th: Heat sensors.

With all this said there is still a strong chance that your engine is bad.

As you can tell your problem could be anything. Get the factory workshop manual and start checking. The easiest way to diagnose your problem is by handing it over to a rotary certified shop. It might only take seconds to check or it could take hours depending on where you take it. Most Mazda dealers could assess your problem in under 30 minutes most charge around 50$ an hour. If strapped for cash make sure you tell them all you want is it diagnosed and wait for them to finish then take it home and fix it yourself. Worst case would be a bad engine which I can find a remanufactured one for around 1000 to 1800 with warranty. Computer injectors can all be found for under 100 used. If you like the car this is not much to ask. You only paid 1100$ for the car, any car this old and this cheap you have to expect problems. Here is the link to the factory workshop manual check out other things on this site, but don't forget to click on your year manual and download all files for your vehicle if you just open them you will always have to go back to the site to view them just right click the link pages and choose save target as to put in on your desktop. http://www.rx7city.com/techconnect.htm
