Hi all Here's my story : I bought a 93 fd a year and a half ago knowing it was low on compression. I took it home and it started handy enough but it sounded like there was no compression. I used a piston compression tester and found it was very low in th rear so i pulled the engine and found it had lost a tip. I rebuilt the engine and now it's back in the car. I dont have the master cylinder hooked up so there for no clutch. The car started nearly first time but reved up to 3 thousand revs and stopped. I found a loose pipe on the air pump which is why it reved up I think ??? now I cant get it to start again. Its just on the verge of starting, when I turn it over it, it smokes at the back box slowly and smells of petrol ( I dont think it's flooded because I injected 10ml of 2stroke oil into the UMI via the boost gauge line port and still no joy ). Alot of condensation has built up round the engine since i tried starting it. Is there a clutch cut of switch on jap models and does this sound like a bad earth ?? if so maybe i've missed one, how many is there and where are they ?? How do ya test a relay ??

Thanks in advance

That actually does sound like it's flooded. But there is a clutch cutout switch on the clutch pedal itself. If it's bad your car won't crank at all though so I don't think that's your problem.

If it was flooded would injecting oil into the UMI not solve that problem ??

Also my plugs are constantly soaked in oil from the build. Is there too much oil in the housings ???

where are the main ground wires or how many should there be ??

thatpoorguy 01-16-2011 10:49 AM

There shouldn't be that much oil in there. Deflood it, then change the plugs and it should burn all of that out of there unless you have an oil seal leaking

FCme 01-16-2011 01:09 PM

Thanks man It's oil from the build because i was extra generous with it when i was doing the build

But because its flooded with a mixture of oil and petrol the spark plugs cant get sparking so by deflooding do you mean removing that fuse and turning the engine ?? what exactly does that fuse do ??

phinsup 01-16-2011 01:38 PM

If you really think there is too much oil in there I would crank it with the fuse in, put as much fuel into it as possible, if you wash away oil eventually, then change the plugs, pull the fuse and unflood the fuel.

FCme 01-16-2011 02:55 PM

does removing the fuse stop fuel and spark ??

i think it only stops fuel, it will still spark. Thats what it does on an FC, not sure if its the same for FD's

thatpoorguy 01-16-2011 09:28 PM

Yeah, you're supposed to pull the fuse or relay for the fuel pump so you can crank the engine without adding more fuel to the already flooded engine. Use the old plugs to deflood it, then swap in the new ones to start. You may want a battery charger as cranking it to deflood can drain the battery

Thanks for the help boy's I got her running today

She sounds good but there is a random pop in the exhaust and I'm putting that down to a leaky manifold I'll go at that tmw

Thanks again

Glad you got it going.

But if it ever floods again, IMO it helps some to pull the EGI fuse and crank it a few revolutions WITHOUT the leading plugs in place. It will eject some of the fuel out the plug hole. You can let it sit for a half-hour or so and then squirt in a little 2-cycle oil (some use PS fluid), reinstall plugs and crank to start.

FCme 01-23-2011 02:15 PM

Thanks signal thats exactly what I did and have it running smoth but it's my turbos that are leaking I'm expecting them to be fubar as when I opened the engine 3 tip pieces where missing and the only place they could of went was into the turbos I guess I wont know for sure untill the engine is run inn

FCme 05-29-2011 08:18 AM

Ok I refitted the turbos as they were leaking as well as the master cylinder and abs and now the car wont start

When i turn on the ignition the dash lights up but when I turn it to start nothing happens apart from the abs light goes off

Is there a clutch switch on jap models ?? i havn't bled the clutch or brakes yet

I have 12 volts at the starter but it wont turn and my earths seem fine

where do i go from here ??

thatpoorguy 05-29-2011 02:37 PM

Yes there is a clutch cutout switch right in front of the clutch pedal. When mine went bad I did a hillbilly trick but it worked. I suspected it of being bad so I unplugged the harness and stuck a paperclip in the plug. Boom, car starts so I know that switch is bad lol

FCme 06-11-2011 12:49 PM

I found the problem. The starter solonid on the starter was jammed. But the feckin turbos are still leaking. I cant understand why, I refitted them with the correct sealer and fitted everything to the correct torc. There is no reason why they should be leaking and it's worse than befor i refitted them. After the car is started for a few mins smoke starts pouring out from somewhere round the turbos and i cant see where it's coming from. however it doesn't smell like exhaust gas. Has anyone ever had a problem like this before?

This is a great place to vent my hearthake https://www.nopistons.com/forums/pub...R#>/violin.gif

thatpoorguy 06-11-2011 05:28 PM

Start the engine when it's cold and check the oil and coolant lines. If they're leaking it will burn off the turbos and smoke. Once warmed off it may be burning off at a rate that you don't even see any leaking, just the smoke

I think it was just excess sealer cause it seemed better when i started it today Anyway here's a pic I still need to give it a top coat of paint

thatpoorguy 06-17-2011 09:54 AM

Not bad! Is the hood popped a little or is that latched? When I first put my vented hood on it was like that so I had to massage the latch bracket with a dremmel
