I have the above mentioned truck that doesn't want to start first thing in the morning. I have to crank 2 to 3 minutes to get it to start and stay running. It will fire and die repeatedly during that period. I have gotten to the point that I will give it a shot of ether first thing and it will usually start right up. It has good fuel pressure 35 to 40 psi just as soon as you hit the key. I just had the computer rebuilt by AVPRO and it ran great for about a month before it started acting up again. I've checked everything I can think of with no results. I checked the compression a while back and it was good. I'm going to check it again this morning to rule that out. Also once I do get the truck started it will start right up the rest of the day fine.

 

Looks like you've isolated the issue to a fuel problem. So attack that, not the ignition.

 

I assume it is FI and automatic?
