Hot starting

[GTIR1000]

Done a search on here seem to find many topics the opposite way round to mine. But recently i have found that when starting the r from stone cold it turns over once fires up instantly but when warm it sometimes takes a while. Now i have read on here a few things to check and i have cleaned the maf sensor, compression shows 160 across all four cylinders, plugs look ok, i have put a new dizzy and rotor arm on. So would i be right in saying it could be fuel pump related i have just fitted a few minor mods ie filter and exhaust and it seems to be a bit worse could it need setting up properly,or ignition leads but it only does it when hot and im still running the small jap battery they come with when imported

i used to get the same on my fto. start first time from cold, then after stopping then getting back in would not fire. turn off then on again would fire.
i know on them there is the IFS (ignition failure sensor), but could be air in fuel line, lambda. never did sort it, few others had it too for years with no ill effect. could be overfuelling with new exhaust, thus flooding engine a little,..

could be a weak ignition module, they generally cause the car to play up when its hot starting

do i need a new coil and ignition amplifier/module. i had a look on here they seem expensive from nissan are these the same

ps did you manage to see if you had any of those parts/prices

still getting this problem is the above link what i need anyone or is this just a coil, or am i right in assuming it is easy to take the coil and module of to clean them both up a bit

I used to occasionally get hot start problems and stuttering when its really hot out. Then I added a heat sink from an old cpu to the power transistor and mounted it away from the motor. Took the idea from here http://www.gtiroc.com/forums/showth...Paste-on-Power-Transistor&highlight=heat+sink

Since then no problems starting or during hot days.

Mine is mounted like that too; I think I cable-tied it to the inlet piping just after the MAF. - I thought I had a picture, but not on this PC evidently.
