I put new spark plug and wires ,new battery so what should I do next to make start because it's cold here in chicago

Check the fuel pressure when you first come out in the morning.

ARE YOU SURE THE SPARK PLUGS/SPARK PLUG WIRES WERE THE INITIAL PROBLEM?

bad spark plugs should have either white or black discoloration on the spark tips, or be saturated with oily gunk on the spark tips. bad spark plug wires usually can only be ruled out by replacing them with new wires. your distributor(cap) may be to blame, so examine the distributor rotor for wear.

HOWEVER, first test the battery for charge with a voltometer/alternator. it should test 12 volts.

if the battery is charged, you should next test the ignition coil. unplug the ignition coil wire from the distributor end of the wire, and turn the key to the "start" position, while holding the distributor end of the ignitioin coil wire a fraction of an inch from a grounded/unpainted part of the car's metal frame/body. if the ignition coil is good, you will get an obvious spark/arc when the key is turned to the "start" position.

if the ignition coil tests good, you shoud then examine the distributor cap/rotor for wear, and replace the distributor cap if it is questionable. next, you move to the spark plugs/spark plug wires. replace the spark plugs if they are questionablke (as you have likely done) and then replace the spark plug wires. if all of this os done, and it still not start, then you PROBABLY have bad compression, or a broken timing belt/chain. there is a special meter to check piston compression, and, if the compression checks good, i FINALLYwould move on the the most expensive possibility of the timing belt/chain being broken.

i would recommend purchasing a "hayne's" or "chilton's" repair manual for your specific model vehicle at an auto parts store for around $20. all the diagnistic techniques/procedures i have mentioned are illustrated or described in these type of manuals. i am not aware of a method to check the timing chain in detail, buit a rough description of such a procedure would be to remove the cylinder cover, put the car in gear, and attempt to push/tow the car a very short distance while in gear/drive- afterwards checking the rocker arms to see if they moved while the vehicle was moved in gear. this procedure should also be described in detail in a "chilton's" or "hayne's" manual.

CHECK TO SEE IF YOUR COMPUTER AREA AND CONNECTORS IS GETTING WET,WINDSHEILD OR DOOR SEAL MAY BE LEAKING IN

i would next try new plug wires and plugs.....hope it helps

Make sure to use 10W-30 oil at oil changes so that the starter doesn't have to work so hard to turn the engine when cold. Have Autozone or similar business check (for free) the operation of your alternator so that the battery is in peak shape. If your trips are fairly short, the alternator may not have sufficient time to restore the energy lost during the start procedure. You may need to augment the battery overnight with a small trickle charger every few days. Make sure the spark plugs and plug wiring are in good condition. Good luck!

the easiest way ids yo put the car on jack stands and go from underneath with a extension a swivel and swivel ratchet. when the engine is cold remove the plug wires and reach up between the exhaust pipe and twist and pull wires off, it is not easy. Next be prepared to buy new wire set if you have not done so already. Then take the plugs out one at a time. use dielectric grease on the end of the spark plug wire that connects to the plug put a tiny bit around your pin-ky finger and rub the new wire with the grease so it will not jump spark. next gap the plugs spray a little wd 40 on the threads and insert plugs while you have the wires off tighten the rear valve cover bolts while you have it jacked up.

Charge the batteries. take a Reading to make sure that you are getting almost 14v to both batteries. If it is not charging then take the alternator back off and have them check it. you might have bought a bad one. There is a way to test the glow plus with out taking them out. ( Take a piece of wire long enough to reach all the glow plugs from the battery. unplug the glow plug wire.If you touch the end of the glow plug with the hot wire it should make a little spark. if no spark then the glow plug is bad. do this to each one, but one at a time)

I suspect that your spark plug wires or your distributor is going out. Check your spark wires and distributor. To do that take out #1 spark plug wire from the spark plug. Next take out your spark plug then put it in the spark plug wire. Then turn on car and take a look at the spark plug to see if it's getting a spark. Do this with all the spark plug. If it is your spark plug wire I would replace all of them.

is it at idle if yes change your idle air control valve.

Check the condition of the wiring coming off of the ECM. at the fender. I've seen the wiring insulation rub off causing no starts.
