Hi lately my fd3s on stock twins is struggling to start when hot. It starts first time when cold and warms up fine etc.
When i stop somewhere to get fuel etc i try to start it hot and it just turns over tries to fire and if i leave it turning over for about 10 seconds and pumping the throttle it starts up and then runs fine again.
i have done a compression test and it all came back fine with good readings i have only done 1000 miles since the last rebuild and has only just started happening.
Only other thing to add the battery is a dry cell battery located in the boot and it has started happening since that didnt know if a bad earth could stop it from starting hot does it use more power to start when hot?
Thanks all.
Out of interest what were the results of the comp test and was it done using a rotary tester
Agreed. Also how fast does your starter motor spin the engine
A rotary tester will give an exact compression value for each face and give you the engine crank speed as well.
That\'s a good point it wasn\'t a rotary tester a normal one make shift. Can\'t remember the results i remember they were nearly 100 think it was about 98 and one was a little lower. Where can i get a proper rotary tester from.
Thanks for the replies guys.
Proper Mazda tester is lot of money. Best option apart from spending loads is get to a specialist or call out jit
Definatley jump it connected to a good power source and compare crank speed to another car before getting to involved,
sometimes a hot starter cranks slower then a cold one so maybe compare the two,
unfortunately hot start is one of the most common signs of low comp,sticky seal or something,have you given it a hardish run?
Haven\'t given it a thrashing for a while now. Its all apart at min so going to get fuel injectors tested then sort battery out give it a test and if still no hope will get a proper test done
may just be a sticky seal then mate,when its back together open it up n a longish drive you may find it clears it.
hi cush not seen you on here for a while,
Hi mate i haven\'t been on for a while. Bought a house so the car had to come of the road but now its time to try and get it running well and back on the road as i miss it. How are you
im good m8, my rex got hard to start when hot and then just before xmas it went bang so its on drive dead at moment
Wonder what percentage of fd`s are dead on drive compared to those on the road.
Hay fokes mine is the same!!! Not had a re-build yet so hoping its not that!!! Just putting her back on the road for the summer!! So think she might need a good thrashing and changing the plugs might help!!
Just out of curiosity what size of battery is best!! I\'m thinking that the one I got give ain\'t strong enough!! Where is the best place to buy one!!??
Are these cars on pfc or standard ecu? It could be crank settings, I also have a compression tester if one is needed.
Standard ecu for mine!!! Dose start eventually but I really hope it\'s a spark problem!!! Starts good cold tho!!! Confused.com
I also have standard ecumenical. And starts perfect cold also its annoying
Bloody phones and predictive text. Ecu not ecumenical.

Lol predictive text is quite funny tho!!! Lol it\'s really annouying when warm or been running for a while!! Changing the plugs and that tomorrow so see if that helps!!
