Clutch pedal

A friend and I changed the clutch pressure plate throwout bearing and flywheel in my 1996 tacoma 4 chk. 2we truck. All went well until we are trying to bleed the clutch. It will not pump up enough to even engage into a gear. I can easily put it in gear when not running but when I start the engine I literally have to stand on the clutch to keep engine from stalling. I'm so frustrated. I need some input. Never had this problem on Nissan or mazdas. HELP

 

you have a clutch master and then a slave cylinder, did you service these.

 

You have to unscrew the line from the slave to bleed it, have someone pump the clutch and keep manually pulling it back out while you collect it below, or use a big bucket
