I have a 93 cavalier that I just put a ignition lock cylinder in. I have replaced the tpi. the iac the intake gaskets, repaired all vacuum leaks and installed new brakes. I can't get the car to start withiut using starting fluid. It will then run fine except it runs too fast(about 1500 rpm) it has spark at the plugs, it is getting air and fuel, the exhaust is not blocked, I need help. It is my daughters car and she needs it for school and work.

Hi my name if Tom and I am here to help you.

You certainly know your way around cars. I have a question for you. I do not see anything about a tune up or check for faulty wires, rotors, distributor cap, and especially timing. Have these been done recently?

It sounds to me like your timing is too far advanced. Do you have or can you borrow a timing light. Even without one you can check the timing the old school way.

Loosen the distributor so you can just rotate it. Rotate the distributor using an insulated glove. Oven mitts work great. Listen to the engine and when it is running the smoothest tighten the distributer. You will be within 1/2 a point.

I trust this was of help. Please, call or email me with a update. I am interested in your reaction to my suggestion. I would bet your timing is too far advanced. This causes the engine to run lean. This would explain the starting with starting fluid, the running fast, etc..

Please call or email me with your results. If I can be of further help or you have any question, please feel free to call. Either way, please give me the number of thumbs my advice is worth to you.
