Hot start problem


Recommended Posts

When hot my glanza seems to take a while to start and sometimes idles weird and cuts out my forts are fuel pump as I've got td04 on it atm with 0.5bar of boost any one else had this? Before td04 swap it would fire instantly and when cold it does

the standard ecu fuels fine with 0.5 bar on td04 so the problem could be plugs? you running iridiums?

does it drive fine? any hesitation or jerking at low rpm?

It's got fuel pressure reg as well to help with fuelling, the car drives fines boost fine screams fine dumps fine but just cranks for about 10seconds to start instead of 2 seconds and idles low till I drive it, I do have iridium plugs in it, I know it's probs due a service but only started doin it since td04 swap which baffles me

Have the spark plugs been replaced recently? It's one symptom of tired plugs.

Not for awhile last time they went down it misfired like mad that was about February time actually so may need changing , I will whip them out in the morning and take a look at them

My also does this occasionally and I've got about 4 month old iridiums in there, could using the wrong heat grade cause it?? Would like to know what's causing it tbh.

Proper ennoying ain't it it mine use to start 1st attempt now takes ages when hot
