So I finally got the truck to run pretty good but is hard to start.
I get 2 sec fuel pump at key on, no pump during crank then pump on after crank stop. I have crank signal at c9 all the way into ECM. If I jump fuel pump prime it will start then run with prime lead dropped. I have tried a different chip and different new ECM. still does it. What else can cause this I am getting pissed off with it?
