Huh. Perhaps I spoke too soon. After the new computer it had been running a couple of weeks pretty well. Got it registered and on the road, while I planned on getting out some more minor issues. But now it is starting inconsistently (ie it doesn't start any time I actually have to be somewhere). I'd like to take a closer look at the fuel situation and make sure it is getting fuel while starting. I had checked fuel pressure at the rail before (not running) and it was within specs. I hadn't checked it running, but once it starts, the truck runs fine. I just wonder whether it is getting gas while being cranked. I'll try squirting some gas in the intake and see if that helps it to start. Let's say that that it does. I'd like to see if the injectors are getting a signal. If they are not, what would be the next step along the pathway to check?
