MACKS Posted March 16, 2006 Share Posted March 16, 2006 bulldog man-the electrical system will not keep it from starting if your pull starting, since you changed the fuel filter you might have air in the system, if you have a primer pump on the side of your injector pump loosen the inlet hose where it goes into the injector pump and then pump the primer until you have a steady flow with no air comeing out, tighten the hose and give HER a pull. If your getting good fuel to the injectors SHE should fire up. Good luck with HER!! PS make sure the fuel shutoff lever on the pump is all the way open.

PS make sure the fuel shutoff lever on the pump is all the way open.I have the s/p switch etc...but I agreee with MACKS, if you can't get it started by pulling it, something else is wrong. More than likely it is something with the fuel system...

bulldog man Posted March 17, 2006 Author Share Posted March 17, 2006 Today i cracked both lines that i replaced saturday & reprimed system (handpump ) clean fuel came through thankfully (i done this thinking some old fuel might had still been in system & might had geled & check see if i had any air in it as well ) also checked the shutoff lever is ok as well, thinking maybe trash in line maybe any ideas ? but i dont if i mentioned this yesterday or not i couldnt get him to start by igntion(spell?) switch even w/ 2 brand new hot batterys thats reason i thought of the parallel switch maybe a loose ground wire somewhere other than stater (i checked that one ) that im unaware of ? maybe generator ? ideas yall? the fuel problem isnt driving me nuts like the electrical problem is electric was never my best thing even to this day but this "pup" is willing to learn im gonna get my buddy back over again this weekend since i checked lines & try to pull him off again . Yall have a goodone Mack Quote You Cant Fix Stupid. But You Can Numb It With A Sledgehammer.
