have 08 grand prix. sometimes in the morning it just cranks but no start for the first few min. then sometimes while im driving it stalls and wont start back up for about 20 min. no check engine light
fuel pump, tune up, crank sensor, and ignition control moduel have all been replaced and
the car is still the same.
Might try replacing your fuel filter, sometimes something so simple ends up being the problem.
