Starting Time...

[BlackSheepz]

Hello again all, I was just wondering how long it takes most of your cars to start?

I've looked around the web a lot and I've seen a lot of different answers floating around. (1 second -15 seconds i've read is normal but that seems weird).

In any of the videos I've found on youtube most of the ZR-1s start 1-3 seconds after the key is turned. I've been counting when I've started mine and it usually takes 4-6 seconds to start, but it does it every time. When I first got the car it seemed like it took FOREVER to start, but now the 5 seconds doesn't seem so bad.

Is my 5 second start time a problem? If it's a problem what potential problems could this be?

Injectors starting to go? (have them in a box with the gaskets just need to find the time)

Battery just getting tired maybe? (it's from 2013 it says, but the car wasn't driven much before me)

Starter?

Car starts just fine, the 4-6 seconds seems like a long time though.

Thanks in Advance!

Mine takes about 2 - 4 seconds to start. The longer it sits the longer it takes to start. I just started my car as I type this and it took about 1.5 seconds.

My new optima battery seems to help.

I believe there is a 4 second delay before starting. Before I did my starter, injectors, coils and wires, my car used to start with a crack when I hit the key, I loved it. Hit the key and it snapped right to life. After changing the parts, it cranks longer and just starts. Before I changed parts, there was no 4 second delay. The only other change was the chip was reprogrammed because I also did a ported plenum and IH.

While I haven't timed mine, I believe it is about 5 seconds or so. I agree that it seems strange, but it doesn't seem out of the ordinary for a ZR-1

I never thought about it!

Do you count how many seconds it takes for a traffic light to change to GREEN?

If mine sits for a week (every weekend I start it rain or shine) it fires right up.....Maybe 1 or 2 seconds. Same thing if I drive it everyday, in the morning it fires right up, and goes to idle very quick. Now if I'm driving it all day, and stop at a gas station or somewhere for a few minutes, it will crank for about 3 seconds before firing up. Never any longer. I noticed once the engine is really warm, it takes longer, but that is to be expected.

It usually takes 3 seconds and never over 4 seconds to start (very little chain slap)......it then takes about 2 seconds for oil pressure to reach 75 lbs.....after warmed up oil pressure 50 lbs at idle.

On idling down to 750/800 another 3 seconds with Haibeck Chips in ALL.
Thermostat in 95' starts to open at 195 deg and replaced that with 180 deg thermostat that starts to open at 175 deg (180 deg Thermostat in ALL).


And......I use the Battery Disconnect Switch on ALL
With the Battery Disconnect you can Disconnect your Battery as often as you like without wearing out the Original Battery Negative Terminal on either the Battery or on the Negative Cable Connector.

Not a fan of those. They get loose and a bit worn. I was stranded once by one of those.

Thanks all, I feel better about it now.

I asked as my 92 LT1 starts up almost instantly and I knew there was a slight delay starting the Z but it seemed long. it also never seemed to be quite the same amount of time so I started keeping track.(loosely).

Dynomite, where did you get the battery quick disconnect? Thanks!

The LT5 has to find #1 on the crank before it starts, so of the time depends on were it stopped along with what others have stated.
