i have seen this problem in a few 13B non turbo engines. the cause is usually leaky injectors or bad seals. one way around this is very simple but does not fix the problem as it will usually lead to ruining the engine itself. here is what you do. from the off or acc position of the ignition. try to start the car for one second, then turn the key off again and wait till the engine and starter both stop. this prevents the fuel pump from engaging. do this repeatedly until the car tries to start about 10 times. finally start the car but do not let off until you know it i will stay running or 15 seconds as to not overheat the starter. you may have to give it enough throttle to rev at about 3k to keep it running afterwards to remove what is called a carbon lock before it will idle. this has worked flawless for me untill the engine finally went cuz i was to ignorant to fix the real problem (please do not be this ignorant, costs a lot of money to fix)

 

Oops. You're right. My bad.

 

oh..i also used this trick on a motor that sat for 8 months and worked first time

 

Its easy to get confused between the S4 and S5. I do it all the time

You can buy a ECU code tester on E-bay for about $35. It has two LED light that blink out the code.

Or you can build it for about $2.50

I tried the atf about 20 times with a car jumping it, but it still wont start. I did hear more sound coming from the exhaust that normal after doing it about five times but it just wont start. How many times do you think I need to do this or what else can I try?

 

I have the same problem on my 86, which is the same as your 87 is. If you have compression, fuel, air, and spark, the you are talking about leaking injectors almost EVERY TIME. First, don't just think there is enough compression because you hear some....do a comp test. If that's good, then go on to the next thing--air....you said you were testing the CAS before. Do the same with your AFM. It's the metal box that's right under your air filter box. I am not sure about the numbers from memory, so check FC3S.com for the factory manuals, and you will find it in there. After that, check spark. Pull one of your plugs out, reconnect the plug wire to it, and place it so that the electrode end is close to metal in your engine compartment. Then have someone try to start it. Watch the plug, and if you see spark, there you go. We know you have fuel, since you said the plugs had fuel on them. So, then I would pull the fuel injectors and look at those. They have O-rings on them that wear out, and must be replaced. But while they are out, I would have them cleaned and serviced. You are looking at about $100 at the most, and there are several companies that will do this. In the process, they will put new O-rings on. When you get them back, re-install them and see what happens. Before you do any of this, I would also get a Haynes Manual from the local auto parts store--12 or 13 bucks, and read the hell out of it.

 

I tried the spark again and there is no spark, the plugs are brand new and the coils resistance is fine, what else do I try?

 

Do you have a timing light?

 

Someone on another thread had a blown main fuse...might want to check that out...its the 80amp fuse next to the drivers side front strut tower in the engine bay.

 

IF thats blown, his car wouldnt even turn over.

 

i wouldnt spend a dollar on an automatic, unless i sold it right away for more money

 

Brillant statement for your first post...

jarrett

 

whats that supposed to mean?
i have a deep passionate hate towards automatics....

 

OH HO, so if you can't find em grind em huh.

 

well, lets see.... Your #1 post here in the rx7club was...

Not exactly on topic, or helpful in any way.

But I can say that I do agree with you....

I also just bought my 84 rx7 a while ago and this is the first time I have had this problem and it sounds very similar...but all these unflooding methods are said to work for a 2nd gen will they work for a 1st gen or not because it aint fuel injected....

 

The ATF probably will work for a 1st Gen, but I don't know how you would kill the spark and the fuel pump, I gues you would have to ask somone in the 1st Gen section.

 

i am curious if anyone has tried my post. i have done this on 4 2nd gen rx7's and has worked every time

 

Send 'guru' a PM. He runs a shop that does a lot of FB work and he may be able to tell you what you want to know...

 

if you ever get it started remember if you do the ATF trick to get your oil changed! hope you get the car started dude!

 

oh yeah and make sure you changed your spark pluggs cuz after all this they will be fouled with gas and ATF fluid.

 

how can I tell if my igniter/s is bad? The coils resistance are within limits and the plugs are new but the car isnt getting spark.
