Rich Posted January 3, 2005 Author Share Posted January 3, 2005 we used a spark plug tester on it ,when you start the car it has a flashing led in it,we also tested it on his car just to make sure it was not faulty. Quote Link to comment Share on other sites More sharing options...
geoffvalenti Posted January 3, 2005 Share Posted January 3, 2005 So you put he spark plug tester between the coil pack and the plug? Surely there's not a lot/enough room? Did you test it on another Supra? Was the car running or did you test it while it was just turning over on the starter? (the "good" car, obviously not the one that doesn't start) Quote Link to comment Share on other sites More sharing options...

geoffvalenti Posted January 3, 2005 Share Posted January 3, 2005 tested it on a megane, we put the tester between the supressor and the plug and there was nothing If by supressor, you mean coil pack, and there's no spark, then the next thing to check is the fuses. Two, under the bonnet, are marked ECU, they'd be the first to check, but personally I'd check all of them to be on the safe side. Don't forget the ones in the drivers footwell Next culprit on the list would be the alarm/immobiliser, in all honesty probably the most likely candidate.

Rich Posted January 3, 2005 Author Share Posted January 3, 2005 thanks Geoff ,will check all fuses now and see if they are blown or not. Quote Link to comment Share on other sites More sharing options...
Rich Posted January 3, 2005 Author Share Posted January 3, 2005 right checked all fuses in the engine bay,which were all OK,couldnt find any fuses in the footwell,I looked high and low for these,what are they for?the ones in the footwell?all I could see was the traction control ecu,mines ecu,and trl fcd,blitz id III box.

geoffvalenti Posted January 3, 2005 Share Posted January 3, 2005 Drivers side footwell, on the kick panel. If after checking these, and the under bonnet ones are OK, I'd be suspecting the alarm. Matt H is your man for all things alarming When's the last time the car ran? Was it OK one day, and then it just wouldn't start the next?

Rich Posted January 3, 2005 Author Share Posted January 3, 2005 yeah ,hadnt used it for about a month,so the batterry went flat,which has happened before but started upok last time.This time once batterry was charged there was no spark but turning over fine,i'll get my torch out and try the driverside kick well.

Rich Posted January 3, 2005 Author Share Posted January 3, 2005 checked fuses in kick well and ok,so I guess its time to look at the alarm Quote Link to comment Share on other sites More sharing options...
merckx Posted January 3, 2005 Share Posted January 3, 2005 Does the alarm still work? Has it got a cat 1 alarm? If a cat 1 alarm was fitted correctly and was still armed it would prevent the engine from turning over! Saying that, I've heard you can have a few problems if the power goes dead on an active alarm!

Rich Posted January 3, 2005 Author Share Posted January 3, 2005 its got a clifford concept 500 on it,yeah the alarm still works,the red led whch flashes when its immobilised still flashes and then goes off when the alarm is de-activated,fuel is getting there ,the starter is turning,but no spark.

Matt Harwood Posted January 3, 2005 Share Posted January 3, 2005 Very unlikely to be the alarm. Not impossible, but the alarm installer would have had to really know Supra's specifically to have cut the ignition circuit alone. Did the Megane have coil packs or normal HT leads? - If the spark plug tester you used is designed to clamp around a HT lead, it won't work on a Supra. All you need is to get a multimeter or testlight and check the voltage going to one of the coil packs. It should show 12v whenever a spark should be present. (as your cranking, about once every 0.5 seconds). OR Remove a coilpack and a spark plug, lay it on the side of the cam cover, (making sure the thread of the plug is being pushed firmly against the cam cover, but not by hand!), get someone to turn it over and see if you can see a spark at the tip of the plug. You could also try unplugging/re-plugging in the ignitor pack. Quote Link to comment Share on other sites More sharing options...

OK, well your spark tester thing isn't going to work on a Supra, so don't condem the ignitor pack just yet, you may well still have a spark. Back to basics... Have you checked the fault codes yet?

michel lane Posted January 4, 2005 Share Posted January 4, 2005 sounds like an ignitor problem. else it could be crank sensor cant be a cam sensor because there is 2 of them . i had the same problem , turned out the crank position sensor had worked itself loose . that was bitch to fix !!!!! hope its not that . good luck Quote Link to comment Share on other sites More sharing options...
