2002 Buick Century Custom start issue?

If the problem (no start) only occurs when the car is hot, it may be a failing coil or ignition module.

Could also be a bad crankshaft position sensor.

I suggest you get the car started and take it to the nearest auto parts store and get them to pull the codes so you have a place to start in diagnosing this problem.

I'll give you a couple of ideas, but this is by no means a thorough diagnosis.

Bad Ignition Coil – Symptoms & Testing

No start

Black Smoke

Rich Mixture

Loss of Power

Limited Acceleration

Rough / Sluggish Running

Temperature Sensitive (May take time to cool Prior to Starting)

Bad Ignition Module – Symptoms & Testing

Power Loss

Rich Mixture

Engine Shaking

Engine Stuttering

Random Shut-down

Poor Fuel Economy

Shut-off After Warm Up

Strong Smell of Gasoline

Hi, I assume WOULDN'T GO and WONT CATCH, you mean cranks but wont start? To Begin with the mechanic that you take it to should know what to check for. First you check for spark at the spark plugs, then check for pulse at the injectors, check fuel pressure, pressure regulator, and compression. This tests will tell a mechanic where to start looking for the no start problem. On a no spark at the spark plugs, problem could be at the coil, inside distributor, pick up coil, wires, rotor, ignition switch, cam or crank sensor. On a low or no fuel pressure could be a clogged fuel filter, bad fuel pump, fuel relay, bad pressure regulator, improper fuel gauge registering fuel when there is none.No pulse to injectors, could be a bad distributor sensor, bad ECM ( computer) relay. Low cylinder compression could be, depending on engine, out of valve time, wore out rings, bad valves, blown head gasket. This is very doubtful that your engine has major problems. possibly fuel or ignition.

Could be the fuel pump. Sometimes if you give the fuel tank a little kick it will get the pump going again.. But if it goes drive it straight to the shop without turning it off as it will happen again and completely die

Have him check the the solenoid that pushes the bendix on the starter motor.The tend to stick sometimes when they are hot.Try tapping the starter motor with a piece of wood or a plastic hammer.But not so hard that you crack the starter motor housing.Good luck.
