for the past few months now, my car is realy hard to start when its hot. cold start is perfect and fires up straight away and idles perfect, but when the car is hot and i turn it off for about 15mins or more it takes along time to get it started, it just keeps cranking, then it goes to start but the revs are very very low and you need to continue cranking until finaly it starts, sometimes have to pump the accelerator to help it fire up !
ive also noticed if you turn it off, then back on after only afew minutes it will start first go, no probs :S so only happens when its sitting for about 15mins or more...
things ive tried/replaced but still no luck:
turn on the ignition and let fuel pump finish priming then start. still no different
new coilpacks/coil pack loom/spark plugs
Sard 280lp/h fuel pump with direct battery power feed
timing belt quadtriple checked and timing is spot on
compression test @ 160-162psi accross each cylinder
r33 gtr air flow meters, cleaned and tested
its realy annoying any help would be great !
tonight i went for coffee with the misses, got back to the car and it wouldnt start for ages, just kept crankiiiiiing seems like it could be getting worse
thanks guys
