Jonmurgie 2 Posted July 30, 2006 Having had the 1.6 running just the once since I put fuel in it we've been trying to get it to start again since! When we looked over it we realised the AFM was a 1.9 version and we had been checking other stuff to ensure it was all 1.6. Since then the cars not started since! So today I've gone over everything I can think of and have tried/replaced the following: New Dizzy Cap/Arm New Leads Cleaned Plugs (they were compleltey black, but may have been from over-fueling with the 1.9 AFM) Replaced Coil Replaced Ignition Amp Checked Dizzy Wire And after all those things there still seems to be no spark from the plugs So, where should I look to next?

Miles 331 1 Cars Posted July 30, 2006 Check the voltage at the coil, 12 +ve should be there when the ignition is turned on, Same goes for the amp a 12volt signal Share this post Link to post Share on other sites
pugpete1108 62 1 Cars Posted July 30, 2006 is the dizzy cap on the right way round?, may sound sily but i did this once and was scratching my head for hours trying to figure it out , then realised that the cap can be fitted upside down doh or the plugs will now be buggered surely? from fuel soak Share this post Link to post Share on other sites
Dan Ingram 1 Posted July 30, 2006 Go over the wire from the dizzy to the ignition amp again, I had the same problem and it took me ages to figure it out. Share this post Link to post Share on other sites
Jonmurgie 2 Posted July 30, 2006 I'll have to break out the Multi Meter to check the dizzy/amp wire as the Ign. Amp is on the drivers side just by the fuel filter and the wires from that run into the main looms, as does the ones from the Dizzy... I always thought the Ignition Amp was on the passenger side though?! Share this post Link to post Share on other sites

Just like Tesco at christmas!- sounds daft, but if you bought a pattern dizzy cap is the carbon contact/spring o.k in it- I had a new one once that didn't make contact with the rotor arm.

I always thought the Ignition Amp was on the passenger side though?! hmm ive never seen ignition amps on the drivers side before. usually there always on the passenger side by the expansion tank. you can put a spark plug in the end of the ht lead coming from the coil and crank the engine over and see if you get a spark. if you dont get a spark then your problem is either coil or ignition amp. if you get a spark then the problem is dizzycap, rotor arm, ht leads or spark plugs.

jonD6B 0 Posted July 31, 2006 Personally I'd check the connections on the coil. Not that I'm saying that you may have them on wrong though. Share this post Link to post Share on other sites
steve@cornwall 100 Posted July 31, 2006 (edited) Personally I'd check the connections on the coil. Not that I'm saying that you may have them on wrong though. just one multiplug on a ph2 isn't it? Edited July 31, 2006 by steve@cornwall Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted July 31, 2006 I always thought the Ignition Amp was on the passenger side though?! hmm ive never seen ignition amps on the drivers side before. usually there always on the passenger side by the expansion tank. AFAIK all GTi's post 1990 with inlet mounted coils have the ignition amp on the drivers side suspension turret, only the vey early ones with inlet mounted coil still had the amp on the passenger inner wings. Check the plug on the lead from the dizzy, if the car has been stood for a while then it could be full of white powdery rust that is breaking the contact & stopping the spark just one multiplug on a ph2 isn't it?Yes, All coils that are inlet manifold mounted are just one brown four pin plug.

Jonmurgie 2 Posted August 1, 2006 (edited) Thanks for all the advice/ideas guys... was raining all yesterday evening so not had a chance to try any of them yet though! Edited August 1, 2006 by Jonmurgie Share this post Link to post Share on other sites
Jonmurgie 2 Posted August 1, 2006 (edited) Right, have had a bit more of a play... this time I pulled a plug out and stuck it in the end of the coil wire as pug309twin40s suggested (hadn't thought of that!) to see if I was getting a spark from the coil... and I wasn't So, I dug around in my garage and found 2 spare coils and 2 spare ignition amps (at least one of each is known to work). I then did a comprehensive testing procedure with a combination of all 3 coils and 3 ignition amps but still no sign of a single spark from the plug :( I thought that maybe it's the wiring, I don't have a multimeter though, just one of those scredrivers that has a bulb in it. Anyhow, I stuck this in the coil wire that should be positive and it was... the other 3 wires in the connection showed no sign of anything happening even when cranked but I have no idea whether they should or not?! OK, so after that I checked the wiring diagram to see what was connected to what and this Tachymetric crops up. I've seen many other people have problems with this but I've never had an issue... until now maybe?! I was about to swap the realy out for the one from my track car but I ran out of time (and actually can't find it in my track car for some reason?!)... so that's where I'm at right now! As you will gather, I'm a bit of a clueless fool with electrics and it's been AGES since I've needed to ask questions like this... I feel most inadequate!!

Jonmurgie 2 Posted August 1, 2006 Another thought, any aftermarket alarms/immobilisers? Nope, nothing fitted to the car at all... and it did run/idle for a while... once... just the once... Share this post Link to post Share on other sites
pug309twin40s 1 Posted August 1, 2006 could be the tachemetric relay problem. your track car is is mi16 correct? so wont have a tachemetric relay on it. only 8v's have the relay. go get your self a multimeter. then you can test the tachemtric relay by connection the meter upto the wires to see if 12v's is coming out when the ignition is on.Off the top of my head the ignition coil/module wires are an green and a yellow wire of the tachemetric relay(i'll double check tommorrow), which should show 12v's with ignition on.
