Easiest way to check is with a scan tool.In data stream it should show rpms while cranking if it does not then the sensor isn't working.Is the fuel pump coming on? Usually you can clearly hear a buzzing noise from underneath the vehicle while cranking. Roughly 293 cubic inches is a 4.8L

Will crankshaft sensor make 2003 Buick century with 3100 (3.1) engine not crank?


Crank sensor only tells the ignition modual what position the motor is in. If it's not cranking you may have a starter solenoid or starter going bad, bad battery, or other electrical issue, could even be a bad ignition switch.

Why wont my 2003 bmw start


No gas, weak battery, crankshaft or camshaft sensor is bad, fuel pump bad, fuel pump relay or fuse is bad, haven't pushed clutch down far enough(rug caught underneath), fuel filter clogged, ignition coils bad. You need to give a hint as to what you have tried. Does it crank but not start? Does it simply click(starter) and not crank?

Crank sensor


let vechicle sit for a while could be flooded fuel injectors leaking.when fuel injectors become dirty clogged they will leak when you turn off the engine.see if engine restart if its sits while.if car still dont crank check for spark.no spark could be faulty ignition module or crankshaft position sensor and camshaft sensor.have vechicle code scan first before buying new parts.meant to say bad engine coolant temperature sensor will cause no start hot engine and clogged air filter.

Car cranks but will not start. stars for 2-3 seconds. full pump is good. would it be the crank sensor? no codes


It sounds like you need a new fuel filter. It runs until the fuel runs out and the fuel filter is preventing the fuel pump from reaching the correct fuel pressure. If the fuel filter doesn't fix the problem, you might have a bad crankshaft or camshaft position sensor, but this would usually cause the vehicle to die once it has warmed up a bit (when the timing starts to advance).

CHANGE FUEL FILTER CLEAN FUEL INJECTORS.MOST OF THE TIME IF FUEL INJECTORS DIRTY WHEN YOU TURN OFF IGNITION FUEL INJECTORS WILL DRIP FUEL FLOODING ENGINE MAKING HARD TO START.POUR BOTTLE SEAFOAM TO A FULL TANK OF GAS.IF CRANKING TIME TAKES 2 TO 3 TIMES. HAVE CAMSHAFT SENSOR AND CRANKSHAFT SENSOR CHECKED WITH A SCANNER.

The car cranks fine (good battery) but will not


Hey all. I've had my 2003 in twice for the Crankshaft position sensor. In Feb 08 it fixed everything. My car wouldn't start when it had been running for a while. I'd pull into a gas station, then go to start it again and it would just turn over. Same thing just happened in July 2010. They replaced the crankshaft position sensor again, but now it's still doing the same thing. If I let the car sit for 20-25 minutes, it will start and run just fine. However, this time around the check engine light is on and it has never come on. I'm open to any suggestions as to what to try next. What is the PCM exactly?

check your fuel pressure regulator. its on your fuel rail. after you have had it runningpull the vacum line off of the fuel pressure reg and if you see fuel there its bad and needs to get changed and that being bad will cause a hard starting problem
