Graeme Posted December 27, 2012 Share Posted December 27, 2012 As topic title really. Been having intermittent issues with starting for a month or so now, got the cause down to shagged fuel pump. Fitted a new walbro unit and all was good, started first turn of the key. The other night I was driving and I suddenly lost all power, this was due to the distributer working its way loose as my friend didnt tighten it fully when i had it off to check it on his car to see if his one was knackered. This morning went to start the car, fired up first time, drove 5 ft then car died, felt like when you run out of petrol but the car has fuel and is getting fuel to the rail as I took the fuel line off and fuel comes out when you crank the car. I took the spark plugs out one by one and tested in the HT lead, all seem to be getting a spark although it seems weak (spark was orange/yellow, been told it should be blue/white for strong spark), the spark plugs were black and soaked in fuel. Is there an easy way to check the EFI fuse without just fitting a new one? Anything else that could be the problem, I am really stumped with this. Cheers Quote Link to post Share on other sites
turbo Grant Posted December 27, 2012 Share Posted December 27, 2012 Bad earth would is what I'd be looking for. Seen some nice green earth points on starlets. The ones behind the plastics in the foot wells are usually the worst Quote Link to post Share on other sites
ryan lang Posted December 27, 2012 Share Posted December 27, 2012 you checked your ignition timing? Quote Link to post Share on other sites
AdamB Posted December 27, 2012 Share Posted December 27, 2012 you checked your ignition timing?X2, if the dizzy has come loose you will need to adjust the static igntion timing to 10 deg BTDC Quote Link to post Share on other sites
Graeme Posted December 27, 2012 Author Share Posted December 27, 2012 Dizzy was marked before it was taken off last time so just aligned back so the marks match up. Is there a how-2 on properly setting up? Quote Link to post Share on other sites
rmsnoel Posted December 27, 2012 Share Posted December 27, 2012 Black fuel soaked.plugs.dont.sound.good. Lad take.your.car to someone who knows. Parts arnt meant to.work loose so sounds like diy.isnt over your mates.head. No offence but.it.isnt safe for other roadusers Quote Link to post Share on other sites
rmsnoel Posted December 27, 2012 Share Posted December 27, 2012 Id be checkin the lead from ignitor.to.dis Quote Link to post Share on other sites
Graeme Posted December 27, 2012 Author Share Posted December 27, 2012 Im sure the carbon deposits are caused by the car running slightly rich and the fuel by attempting to start the car over again. My friend just didnt torque up enough seemed good when i got it back and worked for about 1 week, heat + vibrations worked loose, freak accident. Car isnt going anywhere so you needn't worry about other road users...Any tips on checking if timing is correct without getting it towed to a garage? Quote Link to post Share on other sites
ryan lang Posted December 27, 2012 Share Posted December 27, 2012 go out and buy a timing gun Quote Link to post Share on other sites
morgey Posted December 27, 2012 Share Posted December 27, 2012 You would need to borrow a timing light. I would try you friends ignition leads mate they are a common problem. If not them try the coil of of it aswel Quote Link to post Share on other sites
Graeme Posted December 27, 2012 Author Share Posted December 27, 2012 I'll see if i can borrow one from someone tomorrow. Quote Link to post Share on other sites

Graeme Posted December 27, 2012 Author Share Posted December 27, 2012 being a bit dense here but what part is that? Quote Link to post Share on other sites
morgey Posted December 27, 2012 Share Posted December 27, 2012 The thing the king lead (the 1 coming off the dizzy going to bulk head) plugs on to. Quote Link to post Share on other sites
Glanza Mac Posted December 27, 2012 Share Posted December 27, 2012 As above Quote Link to post Share on other sites
Graeme Posted January 4, 2013 Author Share Posted January 4, 2013 changed dizzy cap as it was looking a bit tired when i split it, timing checked, battery charged as it was a bit dead. Car turning over easily but still wont fire, where would i get an ignitor from if it turns out to be that when i take it off to check continuity, toyota? could it be anything else as this is really starting to annoy me now.

Graeme Posted January 4, 2013 Author Share Posted January 4, 2013 Could this be an injector issue, just pulled plugs again and they're fairly wet... Quote Link to post Share on other sites
ryan lang Posted January 4, 2013 Share Posted January 4, 2013 they will be wet because the fuel isnt being ignited. its spark you need by the sounds matetiming could be out if you havent already checked it? Quote Link to post Share on other sites
Graeme Posted January 4, 2013 Author Share Posted January 4, 2013 already checked it, every things lining up as it should. I've had each plug out and tested in the lead lying on the block and they all seem to be getting a good enough spark. Quote Link to post Share on other sites
ryan lang Posted January 4, 2013 Share Posted January 4, 2013 ignition timing mate Quote Link to post Share on other sites
Graeme Posted January 5, 2013 Author Share Posted January 5, 2013 Timing wasn't the issue, had it checked all was good. I threw a new set of plugs in it today even thought the old ones seemed fine, car is working again, although i cant work out why just happy it is. Quote Link to post Share on other sites
morgey Posted January 5, 2013 Share Posted January 5, 2013 Was the ceramic cracked on the old plugs? Quote Link to post Share on other sites
Graeme Posted January 8, 2013 Author Share Posted January 8, 2013 All intact mate Quote Link to post Share on other sites
jellybaby Posted January 9, 2013 Share Posted January 9, 2013 (edited) Moisture in dizzy cap ??? Mine used to stuggle after Heavy rain turned out to b dizzy letting water In also if the plugs was worn to a certin extent the electrode inside the plug would b broken down so would give a poor spark etc Edited January 9, 2013 by jellybaby Quote Link to post Share on other sites
