Top 20 1987 Mazda RX-7 Questions & Answers

Give the engine some time to acclimate to the change in viscosity.

With the FC3S platform you first need to make sure the battery and wiring are good. If the lights dim when using the starter there is an excessive draw which would indicate a bad starter. if there is clicking or no clicking at the starter voltage needs to be checked going to solenoid. If starter works by bypassing the solenoid, it is a bad solenoid.

check if you have good clean fuel in the tank, has it been sitting for a while?

It would be a fuse or wiring issue not starter if there is no power to the ignition switch. Ignition switches were not high failure items. The 86/91 RX7 had electrical issues. Check fuses, grounds, battery cable ends(for corrosion in wire at connecter, swollen looking wire) look up all the TSB's for the car. If you like working on the car yourself, get alldatadiy well worth it. And go to foxed.ca to download the FSM. (mazda factory shop manual)

Sorry champ, you need to be more specific, what is wrong with your fuel system?

The side seals for the rotors are bad. the only thing you can do is pull the engine apart and replace the seals IF the side housings are good. If they are bad, you cant machine them, they are JUNK. Find a shop that rebuilds Mazda Rotary engines. Mazda may be the best place to get a reman engine.

if the starter is good then you could have a problem some of these had and that is the rotor tips stick to the cylinder wall due to different things.this does happen just the way you discribed your situation.you can try to put some oil into the plug holes and let it sit then try to turn the motor over,you can also try turn the motor over with a wrench or johnson bar and socket.if this won`t help you can try pushing the car and engaging the gear to see if it will break loose.these are some things that have been done by techs to get these rotory motors unstuck.

Hi,

Thank you for contacting fixya.com.

The best solution to this problem is to give your vehicle a little time. Prop up your hood and wait for a few minutes before you attempt to start your car again. This time, be careful of how much fuel you're sending to your engine system. In short, don't depress the pedal too much or too often.If this doesn't work, then you may need to actually open your vehicle's carburetor and you will need to use some WD-40 or ether-based spray to dry up the excess fuel before you can start your vehicle again. WD-40 and ether sprays are highly flammable, so use them with caution. And please don't leave your vehicle running and don't smoke while you use these flammable products. If while doing this you find out that your carburetor is no longer in good working condition, then do replace your carburetor with a high quality replacement part.

Have you checked your ignition fuse yet?

your engine is blown. either find a replacement engine, or have it rebuilt by a reputable engine rebuilder. sorry for your loss.

Hi

You say no electrical power to switch??? do you mean the car will not even light up the dashboard or just no ignition? it could be a number of things, did you have any battery lights on?? also does the car battery have good connections as a poor connection will cut the car out. make sure that the earth / ground end to the car body are secure as this is often the cause, poor battery terminals or poor connections.

Get back to me with more info

very hard you better think twice.

Hi,

Check the vacuum hoses and valves in your engine.

Sounds like the EGR valve, but but check the vacuum hoses, it is connected to all the valves in the intake system.

Then tell us afterwards if there are changes in the rpm!


Hope that helps you out!

See if you can find another engine, it takes a lot of expertise to fix your problem.

is it losing coolant? what does the smoke smell like? sweet? like burning anti freeze? if so it needs a new engine. I have found the dealer to have the best engines.

Well the most common swaps are putting in Small block ford's and Chevy's. The one I see mostly is the 5.0 Mustang motor swap. There are numerous kits for motor mounts and relocation brackets that make it a fairly straight forward swap. Do a little research and you will start seeing quite a few results that will answer your questions on How to's and so forth.

OK most stock engines for daily street driving use the NGK BUR6 and BUR8 spark plugs the 6's go in the Leading side so the bottom 2 spark plug holes. The 8's go in the Trailing side which is the top 2 spark plug holes.

Now as far as the plug wires. You have 2 coil packs one will have markings by the output tips that say L1 and L2 the other will say T1 and T2. its very simple L= Leading side, or bottom plug. T=Trailing side or top plug. 1=Front rotor, 2=Rear rotor.

Hook up everything that way and you should have no more issues.

The starter is mounted on the driver's side bottom of the engine.

1. Disconnect the negative battery cable.
   
2. Raise the vehicle and support it safely with jackstands.
   

Starter mounting-1986-89 RX-7

1. Disconnect the heavy battery cable from the terminal marked B on the starter solenoid (or magnetic switch on later models).
   
2. Disconnect the thinner ignition switch wire from the terminal marked S on the solenoid/magnetic switch.
   
3. On vehicles with automatic transmissions, remove the front starter motor bracket bolts and the bracket. Remove the two starter attaching bolts and remove the starter.
   

To install:

1. Support the starter by and hand and position it onto the flywheel housing. Install the two mounting bolts. On 1986-89 RX-7s, torque the bolts to 24-33 ft. lbs. (33-45 Nm). Install the front starter bracket, if removed.
   
2. Connect the starter wiring to the appropriate solenoid or switch terminals. On 1986-89 models, torque the B terminal (battery cable) nut to 8 ft. lbs. (11 Nm).
   
3. Lower the vehicle.
   
4. Connect the negative battery cable.
