Hey guys... Need to pick some brains if I may... Just finished head gasket job on friends lbz... Did an egr delete and dsp2... Having an issue getting it started .. It will crank (almost like bumping the starter) then stop then won't crank at all... Occasionally it will crank like it's going to start but it doesn't just stops cranking .. Batteries are full charge all grounds are good tight and clean tried numerous keys... Have not hooked it up to scanner yet that will be later morning.. Any Input that could be of help would be appreciated .. Thanks In advance!
