Thanks, but I failed to mention that the battery was the first thing I changed. The dealer says it has spark, and it has power and fuel at the injectors. Apparently the ground is not pulsing at the injectors. This is regulated by the computer, which is new. It starts when it's warm, the weather has been nice, so now it's starting, and it's impossible to troubleshoot! I'm bringing it home and it will be a fair weather truck, or going to a relative's in Florida! hum... how about a carburetor?
