what you are describing is normal. it's the pre prime feature and LP will start running again when cranking the engine

Yeah, i'd be worried if it ran as long as you left the key in the ON position. It's perfectly normal as stated above. The same goes for almost every vehicle with an electric fuel pump nowadays. Worst thing is that it makes these hard to diagnose when you don't have anyone to help you, you only have a few seconds to test for power to the pump LOL

I spoke with him today, I suspect another dead Flight Systems POS. I told him to find a NOS Black Stanadyne. That solved my problems with my Burb. His lift pump appears to be functioning normally, he just didn't understand the way the OPS works. He tried the spare I gave him with the truck but it was a questionable unit as I had removed it form my Burb because of no cruise so it could very well be dead. He is running again. Truck started after sitting. He may also have IP issues. The IP is about 2 yrs old but he ran kerosene through it and it immediately set an IP death code so I told him to run heavy dose of D911 and 2 stroke and pray. So far the code has not returned. I think the pMD is to blame it is a 1st gen DTech I got from Leroy. Unfortunately it is over a year old IIRC. I had bought it after the getogether with TD and Matt and CTChevy. Don't remember when that was.

Our GTG was last summer when I was up there going thru the steam field engineers school @ Schenectady & had a weekend off probably June or July ??? as I graduated the course in August.

I think on these models the LP runs as long as the glow controller cycles.
It does on my 98

You are correct, also on when the lift pump run jumper has +12v applied to it. Post #9 this thread http://www.thetruckstop.us/forum/sh...t-Pumps-amp-OPS-operation-and-troubleshooting from the TRL has a picture of the lift pump run jumper point.
