2008 Silverado P069e
OE module installed and programmed at dealer twice... Dorman module would clear set monitors randomly and while driving ... P069E still regenerates... Wiring, supply and grounds all check ok... ???
A P069e can be multiple problems. It’s just stating there’s an issue in the fuel system. Whats the fuel pressure at ? That’s the first thing to check with that code. How about fuel trims ?
PCM setting P069E? What's the DTC in the Fuel Pump Control Module or Chassis Module?
PO69E means there is codes in the Fuel Pump Control module that need diagnosed. Its the same code as a P0700 Trans Request MIL Illumination. Please let us know what codes are in the Fuel Pump Control Module. Then we can help you.
You just order the Dealer to replace FPCM? Dealer did diagnostic or just replace and program part? As others said, need more Diagnostic in the other modules.
Connector issues a problem with FPCM. Make sure the connector is snug and the seal is not to tight.
You hit the Jackpot Sr. It was corrosion in the connector, as you said. You are the MASTER!!!!!!!!!!
Nadda... The event still happens on the third drive cycle... 5v ref is steady ... Maybe a quick rewire from the rail sensor to the module...?
Yes how foolish of me.... P0191-00 Fuel rail pressure sensor circuit performances .... Replaced pressure sensor first ... then found 1 corroded pin at the base of the FSCM....
Hey at least you figured it out man.

Do not worry man. Once somebody brought me a Cruze, with FPCM problems, they replaced it already, and codes still present. I did a Diagnostic, and find a problem, with the GRILLE LOUVERS in the Front Grille, and they are commanded and actuated from the FPCM in the BACK of the car. Go figure.

Connect a 4 channel scope. Connect to all 3 wires at sensor. Connect last channel at signal at the Fuel Pump Control module. Connect a fuel pressure gauge to the rail. Now drive the car till it acts up. You will find it if you do that.
Thanks gentleman .... Your help and advice is regarded with holy reverence ... after all this the truck is going to wear farm plates... She's pretty corroded and humble in appearance ...Sometimes I'm the dog... Sometimes I'm the tree.. Cheers to all.. :)
