Question about 1991 Chevrolet Camaro

1 Answer

Okay, so we replaced the battery, and the electrical stuff works, but we still cannot start the car. The repair guy says it's not the starter, but thinks it has something to do with a block from the security in the key. Has anyone else had this kind of problem? This is a 1991 Camaro RS with automatic transmission and 5.0 liter v8.

Yes, I have had to change the ignition decoder on my 91 camaro. If u have a second key to the car, try it, to make sure it is not a defective chip in the key.

97 c1500 starting problem, battery or starter or electrical problem?

The solenoid on the starter may need to be replaced.

Won't start from battery but starts from boost. Battery is okay starter is okay

Probably an intermittent ignition switch. Try start it by connecting a wire directly to the starter solenoid and touching it on the + of the battery. Ignition switch must be ON and be sure the car is NOT in gear.

Car will not start,battery good.Turn key in the ignition nothing happens.STARTER WILL NOT TURN OVER.

The car engine must be mechanically okay, judging from the not starting, I would most likely conclude electrical system is fine as well. However, there must be a component, it may probabley be the Engine Ignition Coil(s). These guys are very important so as to supply sufficient current to the starter. Try to diagnose at the dealer to see before replacing :)

Starting Problem

Probably a bad starter as well. A good battery can make a marginal starter work, but over time the battery will be weakened by the drain of the starter or the starter will get worse.

Remove the starter and take it to your local parts store for testing and replacement. Bring your battery along as the bad starter might have toasted it.

Also a bad battery can wear out a starter quickly.

We had issues like this with our pickup truck a few years back. Replaced the battery, worked okay for a while, then the replaced the starter, worked okay for a while, then the battery was bad. Eventually replaced both and haven't had any issues since.

So when replacing one it is a good idea to check the other.

Have a 91 blazer that would not start without a jump. Bought a brand new battery 2 days ago, started yesterday no problem this morning would not turn over. Lights and radio are on. Could it be something...

Absolutely,those starters will start making connections internally when worn out.There by draining your battery.Another thing is oil,if the starter starts soaking up the stuff the oil will make electrical connections all by itself.Try cleaning it with brake clean or starter fluid,probably take a couple cans to get it clean but it might work.Now this stuff is highly volatile and not good to breathe so you'll need good ventilation.The area should be free of cleaners before start up (FIRE!),this will give you plenty of time for charging up the battery.This is a temporary fix,repair the leaking valve cover and replace the starter before it melts down completely.Good luck!

Electrical problem, the lights come on but the engine pre-heater, dash lights don't & the starter does not turn over. The batteries are up and all connections seem okay. Could the engine shut down...

all of that stuff you describe is controlled by the PCM(powertrain control module) on the firewall passenger side. mine got shorted by an overly helpful drunk while jump-starting his neighbors car! you'll a wiring schematic to test if you have output from the pcm, if not it's $700.00 canadian for a new one. good luck
