Starting Problems
Hi everyone, I have a 1993 Caprice LS. The engine turns over but it will not start the first time. I turn the key, the engine turns over but it does not start. The second time the engine always starts. Once the car has been running I can start it on the first try.
I just did a tune-up with a new rotor, cap wires, and spark plugs. I followed the Chevy specifications.
One morning I heard a vacuum sound form the engine (after turning the key) before it started up, and that was the beginning of my starting problems.
To put it in perspective it was about 10 F that morning. The weather had been single digits that week.
I also use the delay for my headlights so they stay on 10 seconds after the car is shut off.
Could I have damaged my battery by leaving the headlight delay on during the winter, or is there a vacuum leak and a damaged battery?
Thanks!

Sounds like it is the check valve in the fuel pump assembly is bad. If it is, you can replace the fuel pump or you can add a check valve in the fuel line near the fuel tank.

That was my first thought as well, I had a fuel pump go out on a Grand Marquis. When I took it to the shop (my Chevy) they said it started fine. I will see about the check valve too.

Great thanks! I will try that and let you know how it goes.
One other question, after I had the tune-up done, I can still feel a slight misfire. Some days are worse than others. I had read a post, where Caprice owners said it happened to them as well. I purchased the parts that Chevy called for. Any thoughts on that?
When I took it to my mechanic he ran a diagnostic and said he could not find any problems. Thanks again.

Thanks for your help. Would you guys have any suggestions about frame work? I have two spots on the frame that have rotted out towards the middle of the car if I remember correctly. Do you think that can be repaired, and if so is it worth the cost since it is a 93?
When I had the car inspected before buying, the head mechanic showed me the rotted areas and said not to worry this was normal for a Chevy. I would like to repair it if possible.

How big are the rotted spots and exactly where are they located? Can you post a picture of them? What condition is the rest of the car in such as interior, body and other rust? A good welder could probably do it. Depending on where it is would depend on how much kit would cost as it is mostly labor.
