What I mean is I'll come out in the morning and when I turn the key the engine cranks once and immediately starts up. At the very most 3 cranks. The car is an 86 gt. my question is why don't other cars do this? Is there a way I can make them do this? My 88 formula doesn't start up as fast either.

my machine shop guy says it's all in the heads! I've freshened up the top end of 2 Honda Goldwings and one 3.4 Fiero. He did the valves and replaced seals on all 3. Just barely hit the starter or turn the key and they start. Doesn't seem like they've even spun a revolution. 5.9 Jeep is another story.

So just a valve job would do it?

in his mind that's what does it. LOL. I really don't know. I'm sure it doesn't hurt, but I wouldn't say it's a cause and effect.

Oh man.....do not pull off your heads and get a valve job in hopes of having your car start on one crank! If your car takes several cranks to fire then inspect your ignition & fuel systems. Make sure you are getting good spark and your plugs & wires, etc are in good condition. If that checks out then check your fuel pressure. A faulty fuel pump or pressure regulator (as well as leaky injectors) may cause a hard start situation. After all that (or before all that) check your ignition timing and reset it to the proper specs. If it still won't start right away then deal with it....it's just one of your cars little idiosyncrasies.

Do both engines crank fast? As suggest above, likely just a gummed up cold start injector or a poorly seated connector for it. Try re-seating it a few times.

My '88 Formula starts instantly from stone cold, even after several days. A 'warmed up' start takes a second or two. Intuitively, seems backwards... My '84 & '86 2.5L always take a second or two. (All are manual trans.)

Fuel pressure might be draining back to the tank, next time try turning the key on and wait 3 seconds before you crank and see if it fires up any faster.. It could also be a leaking injector flooding a cylinder or a sensor giving inaccurate readings.

That makes a lot of sense...the cold start injector has a switch that is temperature sensitive. If the car is cold, the injector works, but if the car is over a certain temperature...( I can't remember the number), the injector does nothing. The engineers figured that the engine did not need extra help if it was warm.

Thanks! As usual, knowledge trumps intuition... Is that only on the 2.8L?
