Crank but no turn

[Roy]

hi thanks again for the reply !

ive ordered new plugs from sumo performance. in the mean time when we removed the plugs we cleaned with carb cleaner as per the guide on the forum, they went back in and worked fine

although they were very black when the were taken out

the miss is like a judder amd the exhause spitts flames, and sounds like a machine gun ! and feels like its holding back

the engine was rebuilt 500 miles ago

it idles higher and lower, sounds as if its about to stall but doesnt, then some times it will stall

I sugest you ring the engine builder and explain whats happening, it may be the case they will sort it out as part of the Warantee?? worth a try.

Just one to check, there is a Little black box with a Vac pipe coming off it bolted to the Bulk head nr the Throttles, This is the Map sensor, Have a good look at the pipe for any splits or damage (maybe a good idea to take it off put your fingure over the end and blow down it to see if there are any leaks, also check its not blocked as it has a little filter in the line), take the Electrical plug off and on a few times to clean the Conections. If all is good put it back together.

Just a word of warning though, Be carfull when removing the Vac pipe from the Map Sensor. (its only Plastic and they brake quite easy, I usaly cut the pipe off nd replace it anyway to be on the safe side but you knever know it may be loose)

thanks grizzly, i will give that a try as well, if you could get me a picture of what you mean that would be a great help.

aparantly when the loss of power first occured, my freind heard a pop, then the loss of power. could the pop have been a bust pipe whilst acelerating ?

[Grizzly]

Its possable, What sort of a Pop was it? Pop like a Miss fire or pop like pressure being let off?

if its loud enough to here inside the car it maybe a Boost pipe or something that holds Pressure?? But i know that an Fd will run without the IC pipes on quite well (smoothly at idle) It may have blown a gasket between the inlet manifold? (if you blow a gasket in the inlet betwen the Throttles and Engine it does odd things to the idle and makes it run rough? but you often here like an Exhaust Blow from the Turbo area too)

[Grizzly]

Just found this pic of where the Map sensor lives. (I hope the owner don\'t mind me putting it up in here

[Roy]

thanks for the pic, the pop did sound like pressure being let off ... i thought id poped a turbo ! lol

you can smell fuel in the engine bay area, but that might be because of the flood

just to help mate, ive just seen this vid and its exactly like mine ... to the T

Where abouts does it smell most? do you see any Liquid fuel about? I know when they flood they do tend to have lots of fuel about but if you get it running and up to temp etc the smell should go?

I\'m guessing the smell is strongest around the Inlet? it could be that its not running well so its overfueling but I don\'t like Rx7 Fuel leaks (the Fuel rail is right above the Turbo\'s)

[Roy]

right near the spark plugs, might be because of me spitting the fuel out when i was turning it over with no plugs in.

just want to sort it, ive only driven it once

[Grizzly]

Ahh ok. Lots of fuel came out then

[Roy]

[Grizzly]

Did you have a Look at the map Sensor?

[Grizzly]

I would say speak to your Engine Builder, There are so many things that would cause that you need to take it to some one that can see it first hand.
