Multiple occurrences. Clock resets itself. Turned key to start, no dash lights, no nothing. . I retried after a couple of minutes, it started. Fuel pump stopped working, no power to it I was told. Fuel pump was new 2/10/13. They replaced the fuel control module 4/18/2013. Connections were cleaned and reset. This all worked fine until 3/12/2014. Same situations started again. But as before it would always eventually start. Same diagnosis, fuel control module and a some other expensive stuff. 3 weeks ago it didn't start, would grind with no fire. Fuel pump isn't getting power. I'm dead in the water. One of my sons works as a carpenter, welder and shipping specialist for a classified government facility. This facility has top notch mechanics to do all their maintenance including autos, going outside of the facility is not an option. These mechanics have 7 chevy 1500s of various years they have to keep running. They've offered that all of their trucks had the same issues as mine at one time. For the first 2 they did the module replacement stuff just like I did. Just like mine those fixes went south again. What they did then was to change out the entire ignition module with an improved version. They've done it for all 7 vehicles as the issues occurred, all are now working well, some for years. I'm trying that next. There may be some security items to fix. It seems to simple to me, but as I look at all of the interfaces of the vehicle with the ignition module, I'm giving it a shot. By the way battery connections are good, grounds are good, fuses are good, I have a basic 2007, manual windows and no remote stuff. If they'll let me I'll post the results.
