Q:celica wants to pulse when speeding up. Mostly when first started. Is this a sign of Pressure or maybe cap and rotor concern.
A:The fuel pressure regulator may be the possible cause of the problem. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.
Q:Would failure of the regulator keep the car from starting up, or would it idle rough?
A:Yes, a bad fuel pressure regulator can cause the vehicle engine runs rough and often stumbles and sputters, engine will not start after ignition, the vehicle becomes noisy at times.
