hi, i have a 1991 camaro z28 sometimes in the morning it crank but wont start after several tries, then the rest of the day start as if nothing happen until the next morning when every thing start again, so if you can help me i will be gratefull. by the way i don`t speek any english so if you can use simple words it will be better

 

Try turning the key on/off so you can hear the fuel pump prime a couple times before actually trying to start the engine. See if that helps.

 

it really help, but how can i do to star just with one key turn.

 

Without some work and spending $$$ probably not.
Just turn the key twice when engine is cold and save your money

I am having this same problem. I have tried to turn the key on/off a few times before trying to start it and nothing it just cranks. If I go back out later, it will fire right up. I put new plugs, wires, cap and rotor on, no difference. I can hear the fuel pump turning on.
