Yo sup My friends got an 88 GTA (we call it the Ghetto Trash Automobile cuz its such a ****). Anyway, hes got the timing way advanced (16* base timing showed on his neighbors diagnostic computer) I told him that probably why his car wont sart when its hot and he wont believe me because his "ASE certified" neighbor says that it needs a new starter, even though the current starter isnt even 6 mos old. Please prove him wrong guys... BTW we already wrapped the headers and replaces the neg. batt cable in case it was a bad ground, but still no luck...

 

does it click when it's hot... if so, shield the starter solenoid, too..

i would think of the car was more advanced it would start easier when the motor was hot, start easier, period..

Too much timing can make a car difficult to start. For your GTA, if it is mostly stock, you should try to have no more than 8 to 12 degrees advance timing (I think stock timing is/was 4 to 6 degrees).

hey, its my car your talking about, and what i want to know is what corrilation does timing and starting hot have?

 

haha, yo sup ghetto trash automobile. You sure you're from NJ?

yeah, im sure, and im sure thats my car, so can anyone tell the what the two have to do with each other?

 

Why not just set the timing back to stock specs and see if your hot start problem goes away? It would cost you nothing.

The farther advanced your timing is, the harder the car is to start. I had my distributer off by a tooth, and the starter wouldn't even turn the motor over. Anyway, when your car is hot, so is your starter. When your starter is hot, it is much less powerful. When the car is hard to start to begin with because of the advanced timing, the addition of heat soak can make it impossible to start.

The answer is yes, reason is you begin to ignite the mixture in the chambers too early and too low of an engine speed, there isn't enough engine speed to continue the piston through TDC, and the "pre-ignition" of the mixture causes the piston to stall.

Now is 16*BTDC enough to cause this? Maybe, maybe not. The easiets way to eliminate this as a cuase is to do as mentioned above, and set the timing back to a more reasonable setting.
