crankcase position sensor ??

[red]

Got a 2001 Chevy 2500hd 8.1L
Close to work yesterday it started choking and trying to die if I touched the gas pedal. In the parking lot it finally died when I was trying pedal reaction in different gears, then would not restart. Towed to a nearby orielys and pulled a p0335 code. Crankshaft position sensor failure. I replaced the sensor and the truck still will not start.

Has anyone else had experience with this sensor? I've read that some folks have to do crankcase relearn by a shop or use a TECH II scanner, yet others don't...

I don't have a TECH II scanner and can't get seem to get a clear direction on if I have another issue or if it must have the relearn done before it will start

Don't know if it will work,but have you tried disconnecting the batteries ? Let it sit ,then rehook and try.

We sell a bunch of plugs for them..............

I'd try changing the fuel filter. Was your check engine light on with that code or did it just pull up with the scanner?

[easeup]

was the security system light on the dash?

Not familiar with a crankcase position sensor. Are you talking about a camshaft position sensor?

When you get ready to sell that truck pm me. I want your motor ��

My NISSAN has two Crankshaft sensors. One (1) I can replace myself and the other one (1) unless you have special tools and a lift ... difficult. The local mechanic only charged me @ $70 so not a bad deal for avoiding busting my knuckles.

Youtube your car model/make and the video was great at walking me through the process.

No errors on the dash, no other codes beside the p0335 crankshaft position sensor. I disconnected the batt just before I walked in to work. Same issue when I came out of work. Did have spark on the plugs. I installed a new fuel pump assembly and filter back in February.

It hit me last night that I didn't hear the fuel pump priming when the key was rolled forward, just before start. Power to the pump checked out good. I pulled the fuel filter and rolled the key forward....no fuel shooting out! Got a new fuel pump this morning, installed it and we are back up and running. It didn't hit me to really check the fuel pump since I had just replaced it a few months ago. and before replacing the sensor, the truck would idle while it acted up when the throttle was touched before it finally died. Had a code checker scan again and no codes, all clear.

Fixed and running great again!

Sounds like a winner

Good deal!

Crank sensor fault will occur if continued cranking and no start. Fuel pump is prob I bet and result is no start and crank sensor code. Jmo Robert
