Chevy Cavalier Will Not Crank Over

1999 Chevy Cavalier.
2.2 Vortec Replaced STARTER AND SOLENOID, REPLACED STARTER RELAY. Question = CAR WON'T START WHEN i TURN THE KEY. If I JUMP IT WITH A JUMPER WIRE AT THE STARTER RELAY IT WILL CRANK. I TESTED TO SEE IF THE SWITCH WAS HOT AT THE STARTER AND WHEN I TURN THE KEY IT GETS HOT. ALSO DO YOU HAVE A WIRING DIGRAM FOR THE STARTER AND SOLENOID ANY HELP WOULD BE GREAT.

Answer:
Not sure which wire at the starter you are referring to. If the purple wire at the starter is hot wwith a test light when the key is turned to the crank position, then the starter should turn over. The large wire is always hot. If jumping the starter relay does engage the starter, then you have a problem before the relay.

Possibly a theft security system problem. If the theft/security light is on after you release the key after a try to crank, but does not start - then you have a security problem. Be sure to check ALL fuses as well. You would need to diagnose wheather the theft problem is in the steering coulmn or the body control module (BCM). Not really something you can do in your garage without a wiring schematic and a volt meter.

Question:
We have this Chevy Cavalier at the shop and it dies when you turn on the wipers. Charging system ok I'm thinking ignition switch problems. I will check it out wednesday to find out was wondering if u heard of this thing, thanks in advance.

Answer:
Yea, ignition switch sounds promising. I would also check something if you have not come across this before. The harness connector under the carpet by your left foot. It is prone to burning. Usually the fuel pump circuit, or the rear defogger. The wipers may draw enough away from the fuel pump to cause this problem.

2.2. Repair work done prior = basic tune-up and fluid changes, brakes, shocks, struts Etc. No mechanical engine failure till now. Work done to repair this problem = checked fuses, other keys, battery is good, installed a new ignition switch. Still my Cavalier won't crank. I notice now the anti theft light on with key on. Question = what is the first thing to check and start working on to fix my problem?

Answer:
You can try to do a theft re-learn procedure. But, that may not work because there is a problem in the theft system. May need the sensor for the theft system. Some diagnosis with a schematic and a volt / ohm meter would be needed, as to not just guess at repalcing parts.

Question:
I have a 2002 Chevy Cavalier that had an inoperable charging system. I replaced the alternator and the battery and there was no change. I soon found out that the alternator was not getting it's start signal from the PCM. I know this because I saw a diagram on the charging system and the red and gray wire that make up the connector come straight from the PCM. The red one is the alternator start signal wire! The car ran perfectly other than the charging problem before I disconnected the PCM plugs to do a continuity test on those 2 wires. I reconnected the PCM and then reconnected the battery and now the car won't even start. Did I somehow fry the PCM by disconnecting it and plugging it back in?? The car does everything normally except start!!!! Please help?

Answer:
It is very possible you damaged the PCM if you disconnected it and did the test with the key on. Or possibly you may have damaged a few of the terminals in the connector or on the computer. Remove the connector and inspect the terminals very closely. Also, be sure to check all the fuses. If all is OK, then sounds like the PCM is bad. You would need a scanner to read alternator cycling data to confirm this.

Question: My Dashboard lights wont come on and nothing happens when I turn the key. 1999 Chevy Cavalier. I replaced the battery and it still did the same thing.
 Answer: Ok. Follow the ground cable off the battery to where it bolts to the frame or the engine block to see if it is corroded or broken under the battery tray. Pull and tug on it. This is a common problem on the Chevy Cavalier. It loose or corroded, replace that cable.

Is it just not getting a good ground? Everything else turns on but the dashboard and radio. But the car still doesnt start.
 OH, OK. I thought you meant at first that there was no power at all. First check all the fuses. Next, try turning the key very rapidly from off to on several times- may be a corroded ignition switch. The turning the key back and forth harshly sometimes will clean up the contacts inside and you may see some electrical items come back to life or flash. Other that, you would need to check for battery voltage (12 V) at several of the fuses that the ignition switch feeds. Low voltage would be a bad ignition switch.

Ok do you know where I can get a schematic for the ignition switch if it is the issue?
 Not sure. That would be a big schematic. May be able to find it online. If not, you would need to get a service manual.
