need help on my n/a motor
 

well, i don't know where else to go, so here i am. I have a 93 audi and i get up to go to work around 8 am and the car runs fine, then when i get out 4 hours later (12) the car will just crank over and won't start. When i go back in the late afternoon the car will start right up. I think it has somthing to do with the heat being about 90 around noon.

Anyone have suggestions?

ground? does it crank at all? if it cranks, its a engine problem, and possible a electrical problem, maybe a fuel problem.

if it doesnt crank,(like a dead battery) most likely an electrical problem.

Fuel injected or carbed? if its fuel injected pull the ecu or efi fuse and crank it for about 15 seconds with the throttle wide open. Sounds like a leaky injector and its flooding

ya, its fuel injected and it does crank over

a friend with a celica gt-s had the exact same problem recently.
he replaced his starter and that fixed it.
check the battery terminals and grounds.
good luck.

I was gonna say the same, except the friend....part.

start simple. it might be something simple. I think it mgiht be something along the lines of a ground. start simple.*for the 3rd time* then check all the other connections, check your fuel pump, spark plugs. if it cranks, its either not getting fuel or spark. you say it gets hot, could it be humidity in your distributer...just throwin out ideas...

ya, its been pretty humid
but, like i said, i can go back in the afternoon when it gets cooler out and the car will start right up. This is like the third time it has done this. So i don't think its the starter

something similar happens to alot of Honda cars. cause = main relay, maybe will help you rule things out.

if it turns over, then its obviously not the starter retards.

sorry, but i HATE when people say "my car wont start, it must be the starter". Its RARELY the ------- starter, and if it was the starter, it would not turn over.
