Just bought a 91 camaro z28 and it will not turn over idk if something is wrong with the timing or a bad alternator ? if anyone has any ideas please help?

 

it wont turn over? probably a starter. motor may possibly be seized up. dead battery?

 

Do your lights work?

 

A 91 will have the VATS antitheft system. If it won't even turn over, there may be a problem with that. Sometimes, the key cylinder on the column gets worn inside and the sensors in it don't read the resistor on the key right, causing the VATS to think the wrong key was inserted. It then tells the ECM which cuts power to the ignition for a few minutes.

Or, the key cylinder was replaced, and has new keys, but the VATS module still has the old resistor value stored in it. The only way I know of to fix this is find out what the value is that it stored and ket a key made with a resistor of that value. Once a VATS module gets a value programmed into it, it can't be changed IIRC.

You can disable it by finding out what the resistor value isand going to an electronics store like Radio Shack and getting a matching value resistor and solder it into the VATS wiring, so it thinks it has the right key. You'll have to do a search on how to do this; I've never done it but read about it a few times.

If the VATS is working correctly, it could be the ignition switch, starter solenoid, starter, oil pressure switch (I think if the ECM doesn't recognize it when you turn the key or get any pressure readings when cranking, it won't let the engine start), or maybe the neutral safety switch on a manual car ot the automatic gear selector that's mounted on the shifter. If either of those two is bad, the ECM will think the car is in gear and won't let the engine crank.

 

The car was working fine when i first looked at it not to long ago the guy brang it home and didnt touch it until i bought it and now it wont start its like 20 degrees were i am idk if that has to do with anythin im 16 years old and this is my first car so i dont really kno to much im gonna try to do the timing i kno it needs an alterantor but idk what else could be wrong o yea this is an automatic

 

Junk IT! JK bro, we will sort it out today for sure...any other ideas guys? I figure i look at all the obv starting from the battery, check spark, fuel...could be VATS but I hope not. Says it clicks but doesnt turn over? starter?

 

ok so I Found out it doesnt ge spark where going to replace the distributor cap coil and fix a kinked fuel line and put a new batter in because the batter is junk any other suggestions

 

If the engine wont turn over replacing the cap and coil wont help the situation.
Also, if you have a 305 that has been bored to a 383 you may have other problems.

 

cars fixed, it was the coil, car also ended up in a ditch tonight totaled. RIP CAMARO lol

 

so the distributor cap was bad well the coil neways fixed that went driftin for awhile the decided to take it 1 last time to get some food well i got cocky and i shouldnt have cuz i only got a permit and i spun out of control and went into a ditch and the car isnt regester or insured so now i gott pay for those a towing fee and gettin back from them stupid pigs

 

Who was acting stupid?
