Hey guys, I hate to bother you with this, but Im having issues with my heavy hauler, but its not a square body. I cant find any info elsewhere, so I figured if anyone would have any ideas, it would be here. Its an 01 C3500HD crewcab with the 8.1l engine. What its doing is randomly dying. No codes, no warnings, just dies. I can turn off the ignition, wait a few seconds, and it will start right up. It may run another week without doing it, or in may not last 5 miles. Its very random. Ive had issues with the 8.1 in a previous 01 I had, but it would at least log a code for a few minutes, then it would go away after it restarted. Turned out to be a crank position sensor but only the factory diagnoatic reader would pick it up, and then it only showed past events. Replace the sensor, and never had another issue. On this one, I cant even get a code, check engine light never comes on, and it wont do it long enough to determine if Im losing spark or fuel. Any ideas would be greatly appreciated.

my buddys 90s chevy work truck would do that due to a bad ground, prob aint your problem but a suggestion

I assume nothing else happens when it dies? You don't lose power to the radio or dash lights etc.? My father in law had something similar and it ended up being the fusebox clip making a bad connection on the ecm fuse. He took his fuses out one by one and cleaned the terminals and bent the connectors slightly tighter. That solved it.

The engine light doesn't come on for the bulb check either? Did you have the crank sensor recall done yet?
Subject:
Product Safety - Crankshaft Position Sensor Engine Stall
# 06083 - (12/11/2007)
Models:
2001 Chevrolet Silverado, Suburban
2001 GMC Sierra, Yukon XL
Equipped with 8.1L V8 (RPO L18 - VIN G) Engine
Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2001 model year Chevrolet Silverado, Suburban; GMC Sierra and Yukon XL model vehicles, equipped with an 8.1L V8 (RPO L18 - VIN G) engine. Some of these vehicles have a condition in which the crankshaft position sensor can fail intermittently or permanently. If the sensor fails intermittently, the Service Engine Soon (SES) light may illuminate and the vehicle may run rough. In addition, the engine may stall, and if so, may re-start immediately or after a cool down period. If the sensor fails permanently, the engine will quit running and will not re-start.
Correction
Dealers are to replace the crankshaft position sensor.

Customer Notification - For U.S. and Canada
General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin).
Customer Notification - For Export
Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the sample letter.
Dealer Recall Responsibility - For US and Export (US States, territories, and Possessions)
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Dealer Recall Responsibility - All
All unsold new vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is shown in this bulletin for your use in contacting customers. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for service in the future, ,you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

Thanks guys. When it dies, the only thing that shuts off is the engine. Nothing else changes.
Vile, I appreciate your reply. The check engine light does work for the bulb test, but thats the only time I see it. I didnt know about the recal, but I will be following up on it now. Thanks again guys, you are lots of help

my first thought was crank sensor. my wife's cherokee did that frequently. It would just die at an intersection or driving slowly. Turned out the crank sensor was faulty, telling the fuel pump to stop pumping. it's like it was in an accident, when the engine stops, the gas stops, preventing a catastrophe.
since Vile discovered there was a recall for that, I'd definately check that.
-
I have changed a million cranksensors in these trucks.
It's really really fun to get to. ;)
Just pray it doesn't break. You have to remove the crank to get at it from the bottom.
-
It looks like I'll be doing it myself. The dealer said there wasnt a current recall for my truck.
Where is it located? I cant find a service manual for this truck, but I have heard you have to remove the starter.

It's located on the very back of the engine near the bellhousing. Just slightly towards the driver's side.

Thanks again Vile, youre awesome

Glad you figured it out. The dealer said there was no recall? Typical!
-
He said it wasnt recalled because it was classified as a commercial vehicle (11,500 GVW)

What a scam.
