smighall 1 Posted April 26, 2006 Just finished putting cambelt on, filling up the coolant etc. Went to start it and it just cranks and cranks. I checked for a spark and that was working fine. However the plugs were dry. So i've looked at the tachy relay and it looks like the joins are dry. So i've bypassed that, hardwiring the fuel pump, and i can hear that running now, but it still won't fire. Anybody got any ideas, i'm all out? Sean Share this post Link to post Share on other sites

Sean Hello mate, I dont want this to sound like im taking the mick but i would definatly check you have put the timing back together correctly. It seems like it was working before you changed the cambelt, now you got fuel and spark tyes but is it sparking at the right moment. Just double check and let us know.

smighall 1 Posted April 26, 2006 Yeah i plan on checking that tomorrow after work, as it's the only thing i can think off. But having checked it about 4 or 5 times before putting all the covers back on, i don't think it is that. What else does the tachymetric relay control? As i think it's shorted, so i've tried hard-wiring it, by putting 12v into the 2 white cables, is that right? Share this post Link to post Share on other sites
sorr 0 Posted April 26, 2006 You sure the dizzy is not 180 degrees out? Share this post Link to post Share on other sites
smighall 1 Posted April 27, 2006 I haven't moved the dizzy at all, but i will try turning it to full advance and see if that makes any difference tonight Share this post Link to post Share on other sites
pip470 61 Posted April 27, 2006 I haven't moved the dizzy at all, but i will try turning it to full advance and see if that makes any difference tonight Dnt move the dizzy, the dizzyis connected to the cam, What he means it you can have the cam 180 degrees out. Its very hard to get the cam 180 degrees out if your carefull. Did you move any either the cam or crank between fitting the belt. What some times happens is the timing mark on the cam shaft jumps forward a little bit cause it was under pressure from the valve springs so you (because its the right thing to do and not moving the cam backwards) move the cam round 1 revolution to line it up but this of coarse puts the timing out by 180 degrees hence it wont start. Maybe some one on here cantell you how to set it up manually. I did the same on a corsa by getting the a set piston at tdc and then checking the valves were rocking on that cylinder ie exhaust just closing inlet just opening. Can any one add to that to clear it up? Share this post Link to post Share on other sites
Phil 0 Posted April 27, 2006 While cranking through an open window, hold the pipe to the fuel rail from the filter and see if you can feel it pulsing. If not (it is very obvious when it is) then the injectors are not firing. I think the tachy relay may have something to do with these as well. This will at least rule out any timing issues. Always worth a check is the plug over the gearbox that comes from the sensor in the dizzy. This has fallen apart on me before and caused the same problems.

smighall 1 Posted April 28, 2006 OK, yesterday i took the battery out and charged it right up. Put it back in, turned it over and it started and then stalled as soon as the fuel in the fuel rail ran out. so then i hard wired the fuel pump up again and it started again. It was very lumpy so i guessed the timing almost certainly wasn't right. I took the cambelt off again, redid it, and the timing holes now match up bang on, but now it won't even try and start again. So my thinking is that the ignition amp isn't working properly so the spark isn't strong enough, but when the battery was fresh from being fully charged, the spark may have been slightly stronger. Does this make sense to anybody else or am i just being thick? Share this post Link to post Share on other sites
smighall 1 Posted May 10, 2006 Right guys, it still won't start. I've just got a new tachy relay hoping that that could be the cause but no joy. Could the ECU be shagged? would you still get a spark if it was? Any other ideas for me to try before i get a mobile mechanic to come take a look.

iety2004 0 Posted May 10, 2006 Are you sure you have re-connected all plugs for the sensors, the thing wont start if it doesn't know, just a simple thing that we all miss sometimes, plus u'll save some pennies if it is the case Share this post Link to post Share on other sites
davev 1 Posted May 10, 2006 OK, yesterday i took the battery out and charged it right up.

It was very lumpy so i guessed the timing almost certainly wasn't right. are you sure that enough fuel is getting through? try cracking the nut just before the injector rail and get someone to crank it over. have loads of rag near cuz it should piss out. if it does then take the fuel rail and injectors out as one unit, lye them on the manifold with some rag just in front of them, crank the engine and make sure they spray a decent amount. hope that helps. dave.

Adam B 0 Posted May 10, 2006 I'd check the plug into the AFM - especially the wiring. This could easily be your problem as the wiring can become broken up or a connection loose in the plug. Check you've got the wire connected from the dizzy to the ignition amp. Check the connections on to the coilpack if an old type on the passenger wing. Check the earth connection on top of the gearbox - make sure its good, tight and clean. Have you deffo got the leads on the right way round? Could the dizzy cap graphite bit have dropped out in the centre? erm thats all I can think of off the top of my head. Go over absolutely everything, unplug, then plug stuff back in. Clean it if its dirty. Hope something in that lot helps! Share this post Link to post Share on other sites
smighall 1 Posted May 11, 2006 It started!!!! I cleaned up the ECT and AFM plug, as well as the butterfly in the throttle body, turned the key and it sprung into life! After starting it a few times it idled perfectly and it seems to be running spot on! So thanks guys for your suggestions! Sean Share this post Link to post Share on other sites
gats15 0 Posted May 11, 2006 I doubt its the ECU as it was working before & they hardly ever fail Share this post Link to post Share on other sites
