I have a 2001 Nissan Sentra 1.8se and I am having problems getting my car to start. When I do it will not accelerate properly. It misses really bad. I have replaced the computer, the mass airflow sensor, cam sensor, coil and plugs. This hasn't helped at all. Could it be something else? Maybe the injectors?

check fuel filter and emissions controls for leaks when was the last tuneup?

replace ur crank/cam sensors. without a proper signal form those ur car will turn over forever without starting.

I would have the coolant checked for hydrocarbons. If there are hydrocarbons present you have a bad head gasket. The misfire at startup could be from coolant being in the cylinders. This would also explain the loss of coolant with no visible leaks and the inability for the cooling system to **** in coolant out of the recovery tank.

Have you looked for vacume leaks at the intake gasket and all vacume lines also chek and test throtle pos. Sensor and idle air control on the throtle body

I would check the fuel filter. They should be changed every 20,000 miles, also the air filter. It maybe time for a tune up. Is the check engine light on?

very first thing i would try is a full tune up. This means the fuel filter , air filter, plugs and wires and possibly the coils. If this still does not fix it then try doing an emissions clean on it. What this does is it cleans out the intire fuel system and is very simple to do. Depending on the transmission on whether its a standard or automatic could be a bad tranny.

Is the check engine light on?? You may have a stretched timing chain, but the only way to check that is to remove the valve cover and look at the timing chain tensioner to see if it is way out of the housing. We see chains on those stretch and cause a running issue like the one that you are descibing, because its out of time. Just a pointer, not a solution, but something worth looking into.
