Help! I am new to owning my '78 vette and am quickly wishing I was more of a mechanic.
The weather has been hot so I drove the car a ton last week and through the weekend. Then on Sunday night when I went to put it away, it wouldn't start. The starter isn't engaging at all. No "grrrrr", no click, nothing. I turn the key to the start position and everything goes quiet. The battery is brand new and I checked the connection was solid to the battery and the starter. The dash lights, accessories, etc.. all work strong when I turn the key on.
Regarding the starter. Usually a starter will give you signs it is wearing and needs replacement. It sounds to me like you have an electrical issue here. In other words, no power / signal is getting to your starter.
Take an hour to check if you even have power to your starter and work back from there.......lastly and most ugly is an ignition problem in your column. If Im a betting man, I'd say its electrical and an easy fix.
Welcome...you may have a problem with the solenoid spring...mine did exactly like yours several years ago...replaced spring,and all was well....you can try jumping across starter terminals (screw driver) just to turn engine...then jump in it to start it...I did that till we thought of spring...(always happened after a drive...)
i just had the same problem and it was a bad spot on the armiture. took it it to be tested and it worked fine but when it would land on the bad spot - nothing. when it happened as soon as i hooked up jumper cables it would fire right off. bought a new starter and havent had any problems in 3 weeks. but also check the battery cables too.

Could possibly be the neutral safety switch. Try if its an automatic moving the gear shift selector up and down the slot while holding the ignition switch to the start position and it may start but have your foot on the brake just incase it did start the car could be in gear. Good luck
Put your voltmeter between ground and the start wire on the solenoid & get a friend to turn the key to start. If you don't have 11V or more it could be any of the following: loose/dirty connections, the keyswitch, clutch/neutral switch, broken/shorted wiring, aftermarket alarm starter kill relay/kill switch in series. You may notice it gets worse when hot; this is becuase copper (wire) gets more electrically resistive as temp goes up. The solenoid needs a good 15 amps to pull in so if you have any resistance in this path you won't even get a click. If you have 11V or more the solenoid is your problem.
Heat absorbption. Starter gets too hot and quits working until it cools off. Sometimes it takes quite a while before it will restart. Happened to our '79 this year. New starter and heat shield solved problem.
I just got over the exact same problem as everyone here. I even jumped it off another car and it fired right up. But after i tried all of this and it still happened i bought a new alternator and haven't had a problem since. The alternator wasn't running the car so the battery could charge up, so after i drove it, i would sometimes get a click or sometimes nothing at all, yet the lights and everything would work. So maybe after you try the above suggestions, don't rule out your alternator.
Another problem with starter solenoids that is a real easy fix is the main electrical contact that the battery cable connects to wears. This can be changed with the starter on the car. Disconnect the battery positive cable at the battery. Then remove the battery cable from starter solenoid. Next loosen the nut that retains this stud to the solenoid. Now turn the stud 180 degrees and tighten the retaining nut and install the batttey cable on the starter and the battery. What this procedure provides is a new surface contact area. Only 1/2 of the surface area of this electrical contact area is used in solenoid functions. This may not solve your problem. Another non start problem I experienced was starter brush wear. I changed out my starter solenoid in a parking lot once becasue my 70 would not start. What the real problem was that the starter brushes had worn down so far they were not getting good contact. Still have the same starter for 35 years, just new brushes about 15 years ago. If your starter is the original one on your car and you want to keep your car "number matching" don't trade in your starter.

Just added that one to my list of "things" to do....have original starter...thanks..
After trying many of the suggestions, I pulled the starter (which was much easier than I anticipated) and brought it in for testing. It immediately failed the test.
I put in a new starter and was off and driving. The new starter turns the engine over much faster and has made for easier starting.
