I have a 1991 honda accord that recently began to give me problems when starting. The car has 245,000 miles on it. Initially it was sluggish in turning over, would catch and try 2 start, start, but roughly, and not want to idle. Recently it's began 2 start only when I put it in neutral (neutral safety switch?). It used. 2 start easily on the 1st or 2nd turn over of the engine. I replaced the coil about 30,000 miles ago, the fuel pump a few thousand miles after that. Any help.would b much appreciated: I'm on a fixed income and don't have the greenbacks to take it to a shop.

You have got good use of it. I through 200,000 was it. Its a neutral switch. About time for new one. I am on fixed income too. Know how you fill.

Car Won't Crank?
This procedure usually works:
·Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

I replace the IAC valve

Sounds like your computer is bad. The car's computer is called ECM or PCM and is VERY expensive and would need to be flashed ($100) for your car's VIN.
