Crank shaft sensor

Make sure battery has a full charge. Check the basics. Have a helper crank it while you check for spark at the plugs, where applicable. Check proper fuel pressure and fuel injector pulse. Usually with sensors, I try to check sensor wiring circuits before replacing, anything. Any applicable trouble codes?
Your year--make--model might be helpful? My database only covers vehicles sold in the US.

Hi, First replace your plugs. Second check ignition coil(s) one maybe bad. replace with new. If all else is good, have your mechanic check the computer codes. (code scanner) Many of todays cars and trucks have computers to run and control the engine. (management system). Good luck

This a code for ignition system The 3x pulse is not being received from the crank shaft 18x sensor Very complex testing to correct this problem. Ignition module and crank shaft and cam shaft sensors must agree for the computer to control injection timing and spark advance

With that much already invested, why give up now? How about the crank position sensor-was that replaced as well? For spark control and spark timing, the computer needs inputs from both the cam position sensor and the crank position sensor before it can know when to cut power to the coils for spark to occur.
Before proceeding any further, you should check for diagnostic trouble codes. You would need an OBD 1 type code reader or scanner for your olds. Any stored codes may help you find the problem.
You can test the ignition system by checking for spark on a spark plug wire when the engine is cranking over. Pull the plug wire off a spark plug and put in a clean spark plug into the wire. Lay the plug so the threads are touching metal on the engine somewhere. Have someone crank the engine over and watch for a spark from the spark plug. If you have a blue, snapping spark when cranking, ignition is good.
One last note: since it dies when driving, there is a possibility that you have a malfunction in the pcm-the computer.

Do you have spark?Just because you have the code doesnt mean its the solution,check you spark remeber the crank sensor signal is at the transmission and the cam is at the cylinder head,is the flywheel broken? is the cam and crank synchronized?check for spark take one plug wire out and leave a 1/4 air gap from sparkwire to spark plug when you crank it should have spark if you have spark do you get fuel injector pulse when you put you finger on the injector you should be able to feel it

check cam shaft sensor and crank shaft sensor replace them

No this does not affect the fuel pump. It will affect the spark though. Hit the gas tank in the center a few times. If it starts then replace the fuel pump. Unfortunetly pumps with a few yaers on them will die when ran out of gas. If it doesn't start pull one of the spark plug wires, insert a screwdriver and put it close to the engine. crank the engine and watch for a spark. if there is no spark then replace the crank shaft sensor. before you replace the fuel pump.

Your engine will also have a Camshaft position sensor too (P0340). This can sometimes make the Crankshaft sensor code come on (P0335). Your misfire could be down to a low oil level or faulty knock sensor. You have ruled out the possibility of it being a spark related issue. Hope this helps...

The first thing you should do is remove your new crank shaft sensor and clean the mount point with a degreaser and your connectors with contact cleaner and a wire brush. Once you do this you should put your crank shaft sensor back in and see if it works if not i would suggest bring it back to the shop you got it and trying to have them replace it because more then likely if it still dose not work you may have gotten a bad censer out of the box.

I hope this helped you.

Thank you,

maybe have autozone or equal scan the computer for codes. could be a misfire in the cyl. somewhere. give me a code number and i will try to assist you further.
