New to the site. Been reading and getting great information for a while. Is there anyone in the Kansas City area that has a Tech 2 diagnostic scanner. I have a rock buggy with an 8.1 in it and having some problems. Used to start everytime no questions asked. It has always cut out under hard throttle but in neutral and park I had full throttle everytime. When there is a load on the motor it cut out. I sputtered the other day while trying to start it and now there is no starting it at all. Turns over fine but no go. Cleaned the injectors, has fuel pressure, new crank sensor. Has spark but seems a little weak? I changed fuel pumps the other day from an E2000 to an E8248. The 8248 made it run bad right off the bat so I changed back to the 2000 and it won't even start now. It is not showing any codes with the scanner I have now. I was told a Tech 2 would probably tell me what's wrong. Any help appreciated. I'm willing to fork out some $ if some one can help.
