Starting....How many "cranks" before your's starts?

[StressPuppy]

I assuming the measurement is

ra - rut = 1

ra -rut ... ra - rut =2

THis is what I was thinking!! I am not anal enough to try to figure out actual revolutions, just going by sound.


As for mine, it seems 3-5 is the norm. I have had vehicles that would start right away, or 1 "ra-rut" so I was thinking there might be something wrong since this was taking longer. But I see that I am not alone.

how did you end up owning an '01 chevy, RT?

Bought it right after 9-11-01 when they were offering really low interest, it was my first new truck (or car) and will be the last, may be my last American vehicle

The oil pump is gear driven so it's pumping whenever the engine is turning. Maybe the circuit is waiting for a minimum oil pressure?

-B-

Maybe but I don’t think so because it would crank much longer after an oil change when the filter and pickup tube are empty, after an oil change my 80 starts in the same amount of time as normal the oil pressure follows several seconds later

I think the pause may be the fuel pump

As there is still oil in the pump, there still could be oil pressure.
THe fuel pump on some vehicles is run by oil pressure. When the vehicle is up side down the motor dies the fuel pump turns off.

I will go out and flip the 80 over and see if the fuel pump works.

oh - thanks -- i am eligible for a gm "discount", whatever that is -- still won't touch the junk --

I think ra-rut is a single cylinder passing through compression. So 4 ra-ruts would be the engine firing on the 4th cylinder to pass through compression.

I think this was talked about in the SOR archives as well. For me about 5 ra ra ra root root pfoot ruts.

Mine always starts before the oil pressure builds, which really weedles me off Usually under 5 seconds. I have often thought of installing some sort of secondary ignition interrupt so that the engine can build some oil pressure before it fires.

 

[landtank]

pfoot ruts.

You have mexican last night?

However, I have yet to start it when it's 30 below.. My answer may then differ slightly..

On the old toyota mini's/runners, the air mass sensor on the air filter has a relay that closes, which then completes the path to ground for the fuel pump. There is also a fuel pump test plug whereby if you short it out, it'll close the path to ground regardless of the air mass sensor. My mini had a problem where it would have to crank 5+ seconds twice on hot (90+) days and dry air (< 20% rh). Although the starter is the original and I've never changed the contacts in the 18 yrs, it was evident the fuel pump wasn't kicking in fast enough. By shorting that test plug, it now starts instantly, regardless of temp/humidity. Thought the 80 might have a similar device.

Usually I just play with it for a little while and I am good to go.

The good old diesel takes 1 crank......

 

[Tooth Fairy]

'93 w/ 260K takes 2-3 ratuts only.

'97 LX w/ 165K takes over 6 every time since a starter change about a year ago. Before that it was 2-3. Don't have a clue what that's all about.

 

[StressPuppy]

My battery was getting weak, so I thought that might have been why mine took more than I expected.

I put an Optima in and it still takes the same number of cranks, but it is DEFINITELY STRONGER when cranking!! Seems like a great battery.

around 4 for me. 88 fj62 w 205k with 3fe engine

 

[tlcruiser]

After counting a few times, I'd say 4-7 cycles.

 

[CruisinGA]

Both ours start more or less as soon as the key touches start. The 93 would be difficult to hit "start" and not have the engine run. The '97 needs two or 3.
