Gordon Bayley Posted January 6, 2023 Report Share Posted January 6, 2023 (edited) Recently I've had trouble starting the TR6, and its getting worse, it used to start with the first turn of the key, I've been told it could be the Piranha electronic ignition conversion that's been on the car from the 1980s, I'm going to try putting the points back in next week . anyone else had this problem? Cheers Gordon. Edited January 6, 2023 by Gordon Bayley spelling Quote Link to post Share on other sites
roy53 Posted January 7, 2023 Report Share Posted January 7, 2023 look at the PI difficult to start posting further down the TR6 forum. Quote Link to post Share on other sites
Gordon Bayley Posted January 8, 2023 Author Report Share Posted January 8, 2023 Thanks Roy yes I've seen it but have a good spray from the injectors, its a quick test to see if it is the electronic ignition at fault as I've been told it does have limited life, I will have a full day on Tuesday in the garage.

Cheers Gordon. Are you getting fat, blue sparks with the existing plugs? I'd open an old plug to something like a 6mm gap and test for a spark- I'd expect the spark from a good ignition system to easily jump that gap in air. Quote Link to post Share on other sites
Harbottle Posted January 9, 2023 Report Share Posted January 9, 2023 How old is the fuel?. Just a thought as one of our club had same problem and after extensive searching it turned out to be old fuel. Paul Quote Link to post Share on other sites
Schnippel Posted January 10, 2023 Report Share Posted January 10, 2023 Hello, very often this is a lack of ground connection. Or the voltage when starting is not sufficient for the ignition system. Just measure the supply voltage when starting. The ignition systems are very sensitive to this. I wish you success Quote Link to post Share on other sites
Mike C Posted January 10, 2023 Report Share Posted January 10, 2023 Does this device use the original ballast resistor in the ignition circuit? If so it might have failed. Quote Link to post Share on other sites

If so it might have failed. TR6s use a resistive wire pink in colour in the harness which reacts with the voltage dropping down to 6 volts after starting. Bruce.

Bruce. Only on post 72 cars. This one is a J plate so it won't have a ballasted ignition system. At least that is what the schematics say and my 1970 does not have a ballast.

I found that that type of R/A failed very frequently with Electronic Ignition but that may have been because I had a Flame Thrower coil? Bruce. Quote Link to post Share on other sites
Gordon Bayley Posted January 12, 2023 Author Report Share Posted January 12, 2023 News so far, a mate came down to give me a hand so we looked at it yesterday, first thing we checked was the ignition and we were getting a good spark at all the spark plugs which I was surprised about. We thought we would check the fuel injection, taking them out one at a time, after a difficult start using easy start to aid the process. Taking each injector out one at a time we noticed differences in each one, a couple had a good spray, some nothing at all and some dribbling. Inspecting the injectors and taking them apart one by one we found all of the o rings had become brittle, causing different faults; I had some brand new o rings from years ago so we replaced them and then we started the car and it started straight away and it is running better than it has been for some time. Conclusion is after a difficult start, the suction from the inlet stroke of the pistons was drawing in the fuel that was dribbling in from the injectors rather than being sprayed. I am going to refurb each injector in turn with new o rings again, I just need to source a supplier, if anyone knows anyone, please let me know. Cheers Gordon Quote Link to post Share on other sites

Gordon Bayley Posted February 11, 2023 Author Report Share Posted February 11, 2023 Update I changed all 6 injectors and now the car start as soon as you turn the key, I had a problem will one of the fuel lines leaking so I had to cut back and refit. Quote Link to post Share on other sites
