ok what are all the things u need to make a rotory start. i know fuel,spark,and whatelse. what r they the things that can make a turboII turnover but not start?? cause the car i got just keeps turning over but does not start up. sometimes after like 10 sec of starting it will start speeding up. what can cause that. even if the motor is blown shouldnt it start?? thanks

 

you probably flooded the engine. it depends how bad you flooded it. worst case you pull out all the spark plugs and disconnect fuel pump. then crank till no more fuel comes out. reinstall plugs and reconnect pump. crank again it should fire right up

 

i dont think that is it but ill try where do u disconnect the fuel pump at?? i mean what else can stop it from starting besides flooding. this is not a easy cause of flooding. this is alot worse. o also what does it mean if u have fuel in your oil dipstick?

 

Well, if your oil smells like fuel, you're probably flooding. Also, your oil's likely thinner, due to the gas in it. That will make your engine *more* likely to flood. Search for the unflooding procedure, as others have written it up better than I. As a start, pull your EGI fuse, then crank the engine for about 10-15 seconds with the gas pedal all the way to the floor. Then, put back the fuse and crank to see if it'll catch. If you've been cranking it for a long time, you might have to do this several times. If this gets it started, *change your oil*. The thinner oil makes it harder to get started, and is overall bad for your engine.

 

hmm ok well that sounds like a plan i will try that first thing in the morning. whats the egi fuse. the one in the engine compartment that is a 40 inj amp right.

 

It's the fuse closest to the engine in the engine compartment fuse block. If I remember right, it's labeled "40 egi inj" or something pretty close. If you've been cranking on it for a while, it's probably really flooded well. It's a common problem in FCs. The classic thing that brings it on is moving the car a short distance and turning it off, though there are a lot of other things that can cause it, like leaky injectors or low compression.

 

o ok thanks so much. but when i go pull the closest fuse to the battery out do i take out all the spark plugs before i turn it over?

 

Erp...closest fuse to the engine, not the battery. The "pull fuse and crank with gas pedal down" fix doesn't require the plugs to be pulled. Pulling the plugs is for if this unflooding fix doesn't fix the problem. You do the fixes in order, until one gets the car running. First, try the fuse pull. Remember to hold the gas pedal to the floor while you crank, it lets air in to blow out the gas. If that doesn't start it, then you get to try the fancier stuff like pulling plugs (you only really need to pull two to blow out the gas) Here's RX7.com's page about unflooding: http://www.rx7.com/tech/unflood-fc.html Ah, and the fuse is labeled "EGI COMP".

 

When I had my TII it got flooded really bad one time. I did all the un-flooding tips and couldn't get it started for 3 days. I finally gave up and had my friend push start me with his car, that got it going!

 

i unplugged the fuel pump. you pickup the rear carpet and there are four screws over a metal plate. remove the six screws. the just unplug it from the pump. crank till you don't see any fuel coming out the exhaust pipes

 

DONT hold down the gas pedal. That is only for 89-91 models. Just pull the fuses and crank it while leaving the gas pedal alone.

 

ok im alittle mixed up. on the procedure it says hold the gas down. and doesnt say about the years and some of u say dont do it. i have a 87 turbo II so which one do i do?

 

Im dealing with the exact same thing as you but Im also dealing with the rear rotor having low compression. Engine has 40,000 miles but the car was parked for a year. I rigged up a switch for the fuel pump...thats the easiest way to deal with it. We're about to go out and pull the car down the road and pop the clutch. That should work

 

Yes, you definitely should hold down the gas pedal. The only difference for 89-91 cars is that the ECU is supposed to cut off fuel when starting with the gas pedal to the floor, so for minor flooding, you shouldn't have to pull the fuse if you have an 89-91. If you spin the engine without pushing the gas pedal, you won't really hurt anything, but it will take a *lot* longer to get the car unflooded. If you want proof, listen to the difference in sound as you crank with pedal down and pedal up. Without pushing the gas pedal, the butterflies are closed and the engine is only pulling in a little bit of air.

 

k, rx7 is running...do what I did

 

i heard that your not supposed to touch the gas pedal at all for 89-91 from a guy that works at mazdacar in atlanta he told me to just pull the fuse out and whatever i do to NOT touch the GAS PEDAL let the engine turn for about 30 sec and repeat that about 6 times and if that doesn't work to bring it in and let him have a look at it but if im wrong someone please tell me other wise i haven't done that yet cause i need a new battery but im going to here in about a week i need more $$$

 

Apparenly the 89-91's have a built in fuel cut, that cut's fuel while cranking if you have your foot to the floor..... I don't know how this works though, bacuase I have a 90, and the car wil definately start if I have my foot to the floor... but it shoudln't because of a fuel cut?
Not sure....

 

For 86-88 (Series 4) RX-7's, do not touch the gas while starting unless you have the above-mentioned fuse out. After the fuse is out, floor the gas, and crank for a ~15 sec WITH the pedal to the floor. Put the fuse back in, and crank without touching the pedal. Crank for about 5 seconds. Don't stop cranking just because you hear the engine try to start, but don't crank longer than 5 sec or so. If it doesn't start, pull the fuse and repeat. If this procedure does not start your car at all, see the "Complex Unflooding Procedure" on http://www.rx7.com/tech/unflood-fc.html.

For 89-92 (Series 5) RX-7's, the fuel pump is disabled when the pedal is to the floor during startup, so removing the fuse is generally not necessary. The '90 GTU I bought recently has low compression in both rotors, so I do this sometimes to start the car. Crank with the pedal to the floor for a good ~15 sec as for the 86-88, stop, then crank without the pedal held. Basically the same as 86-88, without taking out the fuse. If this doesn't work, try the Complex Unflooding Procedure link above.

If you flood often and your compression is sufficient in both rotors, you probably have leaky injectors. Even if your compression is bad, you might STILL have leaky injectors making your flooding problem worse. You might try installing a fuel pump cutoff switch.

Good luck.

 

Interesting... mine will start with the pedal to the floor, but only if I've been doing the unflooding procedure prior and there is some fuel in the engine.

 

so does that mean i should put my pedal to the floor while trying to crank my 90 GXL
