I cannot start the engine because everytime I crank it, it seems that too much gasoline is passing through and flooding the engine. All 4 spark plugs keep getting wet with gasoline. Any ideas on what causes this ?

I dried them out and put some ATF in the lower hole holes and I got the engine to start. The next time I went to start it, the same thing, cannot turn on and wet plugs

I had the same problem, only it was not as pronounced...have you checked your injectors for leakage/cloggage
I would try an injector cleaner and if you are (very) lucky you might get away with it...else, you can have your injectors cleaned professionally, else you might have to change them...always assuming this is the case
Scuderia RX7 list a process for unflooding the car by the way ... I have tried it and it works fine

Get a compression check......sounds like your engine is low on compression.

If your compression is low, as badass7 is implying, and could very possibly be right, a way to get around it for a while is to fit the spark plugs of the FC on the lower two holes...however, you should not go above 200 km/h

I know I should check the compression, the only thing is that the car was turning on fine every single time even after I replaced the fuel filter, then all of the sudden it started wetting the plugs.

thanks

I never heard that this can be done? What are you talking about exsactly? The Leading or Trailing ?? what lower 2 holes?

Shouldnt go above 200KMs? whats that in miles and has anyone tried this theory before??

Spark plugs on the FC appear to flud the engine less, hence by putting two FD spark plugs on the trailing and two FC's on the leading you can get away with starting and not flooding engines with compression in the lower 6's. This is a common scam dealers use in Greece to sell FD's with bad engines...hell, before I bought mine I saw two such cases - hope this helps muzik3k

Riccado the 2 lowers are leading and trailing?
and then You said to put FC spark plugs on the leading. which one is it??

and what is 200 KM in miles

MaxRX7

muzik3k, there are 4 spark plugs.

the Top 2 are "Trailing", and
the Lower 2 are "Leading".

SpiritR

You sure about that?

Did you actually take out all 4 spark plugs, pull the EFI relay out, crank it for about 10-15 sec, re-assemble it and try to start it?

OR did you just take them out whipe them off and stick them back in?

Just to clear the confusion - I am always confused myself with the leading and trailing so supposing we assign numbers
12
34
You would put FC plugs on 3 and 4 (the lower two)
Also, 0-62 mph is equivalent to 0-100k/h so doing the maths a 200k/h is 124 mph

MaxRX7

yes

Okay i dont get it! can someone tell me for sure.

In the manual says that upper right is T and lower right is L, but it doesnt give me the left hand side.

On that picture above says
1:L 2:T
3:T 4:L


When i pulled the sparks out of my car the 2 lower ones were actually Trailing???

Who is right or wrong then???

SaulV

also the blue spark plug wires in the car are meant to go with the trailing and by looking at the wires in my fd. It should be
1:L 2:T
3:T 4:L

Can someone clearify this???
