where to get parts (LPL) for 2000 cavalier?

[rguzek]

My 2000 cavalier does not run on cng as it is supposed to. It intermitently fails over to gasoline when there is plenty of cng fuel. I took it to the dealer and they determined that "the Low Side cut out is bad". They said the part was $1000. I wanted to see if I could buy it somewhere else, but the parts store couldn't place the part numbers they gave me "52369516" for the "valve" and 52369517 for the seal (o-ring, I think). I have a 2002 maintenance manual and I could not match their part number or description either. I think this is the low pressure lock out solenoid, but I'm not sure. Does anyone have experience with this? Can anyone recommend a good place to order factory or equivalent parts?

The LPL P/N: 52368527
Dealer price $104
http://gmpartsdirect.com $75
From the manufacture price is coming. I have purchased one directly from the manufacture for ~$39 + shipping however I am not going to disclose the source until I have verified that it works. I expect I will be cuting the wires off the current LPL and solding the connector on to the new. The manufacture of the LPL said it could be 2 weeks before I get my part that was a week ago.

Thank you for your help. The description they gave me sounds like the LPL, but the part number is different, (Fuel Tank Meter Sender/Connector) I was able to cross it on the site you provided me. Have you ever changed one of these?

Thanks alot.

I have the manual I'll give you the LPL resistance to check it when I get off work tonight. Once you check the resistance that will tell you if the LPL is your problem. I think the dealer didn't get the part number right for the LPL. I haven't changed mine yet however it will be easy. Depressurize the lower pressure side and remove and replace.

That will be great. I have a digital multimeter. I'll wait before I order anything.

Thanks.

Sorry it took so long to reply I have been swamped every night. The manual tells you to disconnect the LPL and put a 12 Light in the pins of the cable to the LPL then crank and watch the light come "ON". Then check the resistance of the LPL is between 6.2ohms - 10ohms. If out of that tolerance then replace the LPL.

I actually never had to replace this component. The problem went away while I was waiting for the part, so I am just holding the part and hoping the issue never returns.

I am looking for a anternate fuel engine control module (AFECM) for a 2002 cavalier. This unit is behind the front bumper. PN IMPCO 52371446, you know I'd like a used one. Thanks Hooper
