need help to gain muscle

[yankees42885]

hey everyone.. i have been lifting on and off for about 3 yrs.. i started off "pudgy" with a high bf% so i went like a crazy man running... i went from about 170 to 128 over one summer.. i was eating barely anything and running alot.. the problem was that i lost alot of my muscle mass too.. so now i am working hard to gain that mass back and even more.. i am 155 pounds right now with prob 10% bf. I have tried for the past two years to get bigger, but it seems my muscle just wont grow like they could before i lost all the weight.. i have tried creatine but it seems to have no effect and i have tried no2 which did nutin.... I have changed my routines several times but nothing seems to work. right now workout is
mon-chest and tris
wed- back and bis
fri- shoulders
sat-legs
I do abs 3x a week and i run 2 or 3 times week...
i usually eat
meal 1- 2 wheat eng muffins, granola bar, egg beaters, protein chake
meal two- turkey sandwich (1/2 pound of it) on multi grain, peanuts, 2 rice cakes
meal three- protein shake, rice cakes, chicken breast
meal four- lean meat, potato, salad with italian or vinagerette (occasionally i will eat 1/2 lb of chicken instead of lean meat)
meal five- protein bars (30 grams), chicken breast
iit usually adds up to 180g of protein, 300grams carbs... 3000+ cals

also when i work out my biceps, I dont even feel the burn that i got be4 i lost the it... I do the reps and the sets, however, the pump disappears quickly and they dont get stronger.. it is the same with my chest... i try to increase the weight every week but it always seems that i just cant do anymore...
if u can tell me wuts wrong with me or whats wrong with wut i am doing i would deeply appreaciate it....

Eat more everything, try to keep the running down to 20 mintues at max. as for your training plateau change the routine reps,order,exercises. just dont stick to a stone written routine
