Toucan Posted November 23, 2009 Share Posted November 23, 2009 Car was sweet for ages, fuel pumps were acting up so decided to change the relay that controlled them, no more issues with fuel pump, fired up an gave it a rev after I had finished to check that it worked, all was okay. Went inside for the night. Next night I crank an crank and it coughs an splutters but no start? Has fuel at rail and in tank, spark at coil, will borrow a plug socket tonight to check plugs, all other wiring is as it has always been, all relays click on when key is switched, tried various ecu's. Timing hasn't changed, cambelt is still in one piece. What am I overlooking, what could have failed overnight. Had builders in our house that day and the bonnet was up but nothing appears sabotaged. Diagnostics gives a single flash of the engine check light every 5 seconds. There is seriously not alot to check, the loom was cut right down to the bare minimum an im fairly familiar with it, it all appears sweet but still doesn't run, im truely stumped. edited for diagnostics Quote Link to comment Share on other sites More sharing options...
Steelies Posted November 23, 2009 Share Posted November 23, 2009 keen to follow this haha. injectors? Quote Link to comment Share on other sites More sharing options...
Toucan Posted November 23, 2009 Author Share Posted November 23, 2009 Not willing to remove them unless absolutely necessary, I have no tvis plate and intake plenum is real close to head and there is no room to get tools in between to get at them. I also doubt they would fail overnight. Think I'll buy new sparkplugs tonight incase, its had super 4's since I've had it, I've never had any problems but have heard they are shit Quote Link to comment Share on other sites More sharing options...
Ned Posted November 23, 2009 Share Posted November 23, 2009 I know you said you have fuel at the rail, but do you have pressure? I'm one to keep looking at the thing you changed before it broke to find the fault, even if it appears to be working Quote Link to comment Share on other sites More sharing options...
Toucan Posted November 24, 2009 Author Share Posted November 24, 2009 Yes Ned, it has lots of pressure. Got new plugs, will try again tonight Quote Link to comment Share on other sites More sharing options...
l1ttle_d3vil Posted November 24, 2009 Share Posted November 24, 2009 pull one of the plugs and clamp it onto the block and crank it to see if you've got spark. try some different HT leads. mine did a similar thing ages ago, left it another night and it all came back to normal. never worked out what was wrong.

Ghosts How are the fuel filters? Hasn't sucked up any crap which could be causing a block? Quote Link to comment Share on other sites More sharing options...
Toucan Posted November 24, 2009 Author Share Posted November 24, 2009 wtf. Looks like selleys all clear or hot glue on the electrode of the sparkplugs. New plugs and it fired up straight away Quote Link to comment Share on other sites More sharing options...

xsspeed Posted November 24, 2009 Share Posted November 24, 2009 +1, also would be hitting up the builders' boss(es) You or anyone didn't piss them off did you? sounds a bit suss/similar to many builders stories I've heard. When my uncle was younger they had this old bird who was refusing to pay for some of their work, so they went fishing one weekend, then nail up the Gib, with the fish inside the wall cavity.

Toucan Posted November 24, 2009 Author Share Posted November 24, 2009 Nah didnt piss anyone off. I don't know what builders were used and not gonna ask property manager, we have already had enough trouble and are on our last life with this place I don't want to go accusing anyone just yet, plus they seemed like good dudes when I was chatting to them. Fucken weird man. Might try do NMR on the shit at work and find out what exactly it is Quote Link to comment Share on other sites More sharing options...

Toucan Posted November 26, 2009 Author Share Posted November 26, 2009 Running like poos again, plugs are pretty black. Grrr Quote Link to comment Share on other sites More sharing options...
KKtrips Posted November 26, 2009 Share Posted November 26, 2009 If you had goopy stuff all over the tips of your plugs it would be a reasonable assumption that the same shit is all over the tips of your injectors - chuck some good quality injector cleaner into the fuel and clean your plugs with some solvent like isopropol. Throw them back in and give it a whirl. (if you can splash out - why not chuck in a new F/Filter while you are at it) I have found CRC (from BnT) and Wynns (from Repco) are the best choice injector cleaners (Redline from BnT is veeeeeery gooood but expensive) Quote Link to comment Share on other sites More sharing options...
Simon Posted November 26, 2009 Share Posted November 26, 2009 Maybe check vacuum hoses too? Quote Link to comment Share on other sites More sharing options...
Toucan Posted November 26, 2009 Author Share Posted November 26, 2009 Pretty sure vac hoses are sweet, theres only like 4. Mate is getting me some injector cleaner, its toyota stuff, meant to be good. Also got a pre pump fuel filter and new hose clamps to be installed. Repco were gay and didn't have high pressure filter that matched my one, all the threads were different? Got some crimps to redo one of the 12v feeds to the ecu. The bosch super 4's got cleaned with some ethyl alcohol and a wire brush, will keep them on standby incase I break down. Yahrgh should be smooth sailing by the end of today I hopes. Then wof tomorrow then time to fix bellett Quote Link to comment Share on other sites More sharing options...
forced Posted November 27, 2009 Share Posted November 27, 2009 If your plugs are black, then it's running too rich. A faulty O2 sensor will cause that, so will a few other things. Steve Quote Link to comment Share on other sites More sharing options...
Toucan Posted November 27, 2009 Author Share Posted November 27, 2009 Came right after a long italian tune up and a good drive, perhaps the ecu was unhappy with being unplugged, or the plugs were fouled, or the fuel was dirty, but whatever it was has come right. Passed wof second time, had to replace a bulb and do an axle seal, easy! Quote Link to comment Share on other sites More sharing options...
