2004 dodge ram 2500 5.9 diesel hard to start

I have a 2004 dodge ram quad cab 2500 5.9 diesel 4x4 it is hard to start you have to crank it for awhile, lets say for 10 seconds or so before the engine starts cranking faster as though it is picking up fuel and then it will start. The fuel mileage has become worse a little at a time. I cleaned the filter cover and in side housing, then the check engine light came on i took it to auto zone they put the computer on it it said maf sensor bad, we could have messed it up but would it make it hard to start as if not getting enough fuel or could the feed/lift pump be bad too. Does this truck have any other pumps besides the injector and the lift pump that feeds the injector pump or filters other than the canister filter i changed trying to fix this problem.

Hi i have a 2003 Ram 2500 4x4 quad cab. the passeger and rear power windows work only from the drivers control not from their switches, i've tried the lockout switch in up and down positions several times...


sounds like the switch went bad. all power goes thrugh the drivers switch before the pasangers side. you my have to check to see if you have power at both switches. you'll probly find that one is bad or corroded

It sounds like you have a bad mastercylinder cause when you panic brake it doesn't have time to bleed through the valve in the cylinder but under normal braking your foot is on pedal longer in turn giving the fluid time to bypass the valve in the mastercylinder in turn the pedal going to the floor.
