Clutch problems .I have to pump my clutch for 15 minutes to get it to shift into gear when car is running. What is the problem

do you mean it wont go into gear ? if so what gears ? it could be the clutch going out , if the pedal is soft or easy to push down than it probably needs a clutch. next time it wont go into gear try pumping the clutch or putting it from 2nd to 1st or what ever gear it has problems with

I believe it's your clutch. If you can shift gears okay with the engine off, but you cannot shift gears with the engine running, (the gear shifter only grinds when trying to shift into first?) then your clutch has worn out.
To replace a clutch, the transaxle has to be first removed from the car. I'm afraid you will have to have it towed to a shop or garage.

If you tow your car in neutral how come is stuck on one gear. Towing got no problems. That mean it wasnt in neutral it was in gear but the clutch is stuck and seem the gear is in neutral. You should have clutch problem before you think about gear box.

your clutch has went out or the slave cylinder to clutch or clutch master cylinder ck master for fluid if low fill and work clutch peddle to pump up slave cylinder if master is full ck at trans to see if slave cylinder is moving if moving clutch in most likely bad and needs replaced.

You have one of these two things going on....Either the clutch master cylinder is internally bypassing or the clutch itself has gone bad. If you can pump the clutch and sometimes be able to shift, the master is bad. If the clutch pedal feels normal, then I'd suspect the actual clutch disc is worn out.
Your clutch has little to do with shifting with the engine off as nothing is turning and engaging the gears is not a problem. Have an experienced tech take a look at it if in doubt ...should take all of five minutes to determine what's wrong.

i would check the throwout bearing, if this is the problem try starting in first go for a while than try up shifting to second. after a while your transaxle should warm up making an easier gear transition. ( this only partains to bad throwout bearing )

check your clutch fluid level, check your primary and secondary clutch cylinders for leaks. if no problem with the above then it is either the clutch cover or release bearing in the transmission.

if you have hydro fluid in the clutch master cylinder and the system is free of air, then it needs a clutch

Still sounds like a fuel problem. Try a full tank of supreme gas, plus put a can of SEAFOAM into the tank to help clean you injectors. See if this will help clear up your problem. Did you change the plugwires????
