Okay, I have the car listed above that has sat for to years because of ignition problem. I replaced ignition,ignition coils, fuel pump, starter, and all six injectors. I try to crank it and it is a slow crank, but if I crank it for about twenty seconds it tries to fire up but does not. is it because my battery is low and is not cranking the starter fast enough to make everything work faster and stronger? Please I need help.

Remove Mr. Battery out and have it tested at an auto parts store, this is usually a free service.

or try these

A jump start from another vehicle.

see my link, sitting may have invited corrosion.

Well it tried to crank after charging it an still would not start, but was acting like it wanted to so I checked the oil just to make sure and the oil had gas in it. so I guess since it sat for two years I need to put a little transmission oil in each cylinder and crank it with out the plugs to loosing up the rings right or are the rings going to be toast. and is the motor ruined now it has got gas in the oil?

Leaking injectors may be the gas in oil issue.

Well the injectors are brand new and have great fuel pressure in lines so even tho the injectors are new they would still leak. what would I do to check?

Compression test on cylinders to check rings and proper seating of valves.

Hi guys. You glossed over the slow cranking and went looking for more involved things. If the engine is still cranking too slowly, start by measuring the battery's voltage while a helper cranks the engine. Put the meter's probes right on the battery posts, not the cable clamps. During cranking, the voltage must not drop below 9.6 volts. If it does, the battery has a bad cell or is not fully-charged. Tell me what you find for voltage while cranking and while not cranking.
