Right having a problem with my n/a fc she has been a bit funny at starting lately (really have to pump the gas thru alot & keep turning the ignition) but usually does start eventrualy but she now won\'t start at all, she just wont fire up, she will try her best but it is just like there is no fuel getting to it, you can hear her turning over strongly & all the ignition system seems fine.... any help or advice please !?!
Help anyone am currently without a car :mad: took all the plugs, leads & cap etc out cleaned them up, plugs are dark & wet with fuel so think i may have flooded the thing, will clean out in a bit but if it isn\'t that im a bit lost, help!?!
Poor starting could be down to low compression :(
Unflood it first, and give the plugs a work over - you might want to charge your battery or get a jump start to help fire it.
Cheers for getting back to me, she has done 80,0000 could she be on the way out when you say low compression??
humm could be .. when i had probs with my egi , i used to cheat :D
clamp the fuel line with locking pliers - crank and wait for her to fire , then get out and unclamp the fuel line - and she should run just fine :D
if this does work - you might want to fit a fuel cut off switch - this way when you have finished with the car - leave it running , cut the fuel and just as she starts to die , turn it off
with this method - it shouldnt flood again
also - with the plugs out - remove the EGI fuse , crank for 10 seconds , then crank again , and then again - this should remove all the fuel in the lines etc... and get shut of any excess fuel in the housing
then put the plugs in , egi fuse in , crank the car - but do not touch the throttle - make sure the battery is fully charged at this point though :D
Arhggg good thinking, right out in the lovely weather i go need to get her running bad, thanks will report back soon!
:waveRight did all the above & still no joy! What was weird thou, was that no fuel squirted out of the spark plug holes just air!! So i take it my pump is naff!?!
doesn\'t the handbook say to just keep you foot on the floor when the engines flooded? My car doesn\'t like warm starts and i have to do this everytime i warm start.
the TII had a cut off on cranking with WOT - not sure about the egi though
OK - what happens with the EGU fuse in , plugs out and then crank ? does fuel come out the holes ?
Hi Mate,
If the plugs where wet as mentioned earlier i think you have fuel going in.
How old are the plugs ? might be wise to throw in some new ones.
Have you checked for spark at the plug make sure the leads are clamped on and check the main engine fuse box, Theres one called "Main" iirc if this is blown it could be the root of the problem.
If she was flooded badly you will need to the following.
Plugs out.
EGI fuse out.
Some cloth besides plug holes to catch excess fuel.
Crank engine a couple of times.
A small syringe with engine oil - squirt a small amount into the housing.
Pop into 5th gear and push the car back and forward.
You will get a good seal between the apex seal and rotor housing.
Put plugs back in and EGI fuse.
Fire her up.
I\'ve found putting oil into the housing aids in getting compression on start up.

Right gonna have another crack at it soon but as i am starting to llok around will a FD fuel pump work on my FC without to much fabrication, thanks for your help??
Right even with the fuses in no fuel was coming out, so must tbe something wrong with the fuel getting to the engine as she sounds like she is turning over really well but just nothing to fire up off!! Also have been looking into getting Walbro pump (is this wise or should i use something else) as having great problems finding a fc pump!?!
you can drop a FD pump in no probs - what you have to consider is that it might not be the pump - the FC\'s have really bad wiring to the fuel pump - so i would check that first
get someone to crank the car - and see if you are getting 12v at the pump
if you are not - doesnt matter what pump you put in - it wont work
have a look on net for the re-wiring write up

Fuel Pump! very important for turbo\'d cars.
It is critical that your fuel pump is getting all the voltage it needs. It takes 10 mins max to test the voltage to the fuel pump.
Get your multimeter.
First attach your positive lead to blue wire and the negative lead to a good ground. The Wiring harness plug is located on the driver\'s side rear shock tower.
The color of the wire going into the plug is blue. The color of the wire coming out of the plug (going into the fuel pump) is black with white stripe.
Lift the carpet that covers the rear hatch area, Remove the rubber/felt noise deadener mat. You should be able to see the wires that run to the gas tank.
A stock FD3S fuel pump costs about 20-30$ used, and has 10-15% higher capacity.
Thanks guys your being abig help, gonna go test to see if i am getting power to the pump!!
Well, looks like i am going to be doing the fuel pump relay rewire!!
Hmm but if the engine has run lean doesn\'t that mean a rebuild anyway?
it shouldnt have run lean at this point ( we all hope )
just get the fuel pump working and work from there

Anyone ever done this re-wire before as i am having problems with it as it is written with for the turbo model it is also a American write up so wire colours are different!?!
im just thinking cause if the car was ok, and then it started playing up it might mean it was ok and then the fuel pump decided to go..

Help, anyone done a rewireon a n/a before???
I would replace the fuel filter first, in case its blocked before any rewiring there as cheap as chips.
Paul
Checked both filters & there are fine, something is not right with the wiring everything else seems fine, has anyone else had this problem thanks!?!
Ok fuel pump problem is sorted, thanks for all your help... Now have another problem woohoo :wiggle my car is over heating the ADD COOLANT warning light & buzzer come on & the resovoir bottle is boiling the water.... gonna have a good look tomor morning to make sure it isn\'t anything obvious... anything i should look out for in particular, thanks???
i mate of mine had this problem - cheapest place to start - new rad cap !

Have you checked your hydrostatic fan is working correctly? They fail on a regualr basis as the cars get older and can lead to a nice little boil up :Nono!
Sorry to sound stupid .... my what fan lol, whcih fan is that thout i only had the one ???
Yeah - it\'s the big white one :Giggle
Ha thout i was being stupid but always good to check!!!
Thats fine :)
Should have some drag when its warm, and less drag when its cold. If it freely rotates all of the time when warm then it\'s shot, if its stiff all of the time it\'s also had it. :wave
Thanks maty will start her up tomor & check it out!
Right had a good look around the radiator & that, cap was a bit shot so replaced that & also made the air intake for the rad & oil cooler but more efficent..... took it for a drive (nice hot day today) all seems fine now & gauge is reading alot cooler. Thanks for your help :mmmm
glad to hear it :D
