ok this is a 97 psd, i just replaced all 8 injector cups, with all new injector o-rings, now after putting it all back together it will not start unless i have it jumping off another truck, and i have to hold the throttle wide open to get it to start, but even when it does start i have to crank it for a long time. I can get it started drive it around and what not, come back let it idle, turn it off, then try to start it right back up and it will start on its own but still takes a few long cranks. If it sits for any period of time it wont start, and has to be jumped again. Any ideas would be great... thanks in advance
