I used Snap - On's best live scanner, came up with same codes, which say that the problem is either the relays or pcm.
I replaced the relays and the PCM was going to be next.
Luckily I had left the truck run for 30 minutes in one place and noticed a drip of fuel on the ground. Inspection with a mirror revealed a pin hole in the return line from the injector pump, causing me to loose my prime, making the truck hard to start in cold weather.
The leak sprayed onto the block and really never made it to the ground while moving. Scanners don't show mechanical problems like leaks, so they diagnose problems as electrical or computer. Anyhow, $87.00 for a new line was a lot better than a new pcm.
