How does YOUR car start?
 

A forum buddy sent me a video, his rotary starts as any other normal piston car, a revolution and thats it, it starts.

Mine sounds like an airplane, gets speed and then it starts.

The question is ..... why???

any ideas?

It's the time it takes to build up compression.

oh...

that cant be good

i think it takes that long usually when u haven't started it up for a while (like mine) or when ur compression is a low

if it takes a push start for the car, compression is low and may indicate signs of major wear on motor.

or maybe you mismatched the spark wires and plugs hence you always having to push start the car; it will only constantly flood if that was the case.

yeah..doesn't sund right, or it could be a bad starter as well. Or your choke ain't pulled out!

Mine starts up almost right away.

with the key!

Winding up is definately a sign of low compression.

My fairly stock 7 cold starts only w/ the choke pulled all the way out. My SP 13B has no choke & takes a slight pump at just the right time to catch. If you miss too many times, it floods. Then you wait 15 min & it starts right up.

13B, sidedraft, Starts up as fast as you can turn the key.
Oh, and no choke. :)

If your timing is off and/or you have weak spark could cause this also.

12As should start right away with no pedal in normal weather and half choke when cold. A 13B may flood when warm and thus require holding pedal to the floor (without pumping!) while spinning it.

Any rotary MAY have coolant leaks that flood the engine and will require some spinning to get started and then start with a sputter. this is such a common problem that it pays to monitor coolant consumption and ability of coolant system to maintain pressure.

<<<<<<<<----------------what kind of front bumper body kit is that.......whats the name

maybe it needs a tad gas in the "chamber" i give mine 2 pumps (weber ida 48) then its good to go. make sure to check out your OMP to make sure its still doing its job, oil helps keep the compression alittle higher.

Mariah?

Uh, maybe in California, where "cold" means anything below 45F. In the northern states and Canada you need full choke and part throttle at any temp below freezing and at least part choke and part throttle above that temp and up to 45F.

wtf! how?!?! i have the same setup and it takes me 4 times for it to get going, and i have to hold my foot on the gas for like 2 minutes to make it idle.. whats wrong with it?

Mine would need the choke pulled out, and the gas pumped heavily and after it wound up enough it would start to a shaky idle and youd have to clear the motor out, later I blew the apex seal and starting go 100x worse

Well,

I have to hold down two wires on the left hand side of the column to get my car started and sometimes it'll actually mess up my start and flood the car because you let off and it stopped cranking...

mine starts never now lol I wish it did I miss it lol

depends on how cold it is, if theres frost on my windsheild i know im in for some hell. Take alot of cranking, and sometimes doesn't even start. On the other hand, in warm weather i never, ever have a problem starting it, if i flood it a bit i just hold the pedal to the floor and it starts right up. I hate the cold!

oh btw - 1983 GSL 74-78 13B, RB Holley 600, RB Headers, Stock ignition system

Trust me, it wasn't always that way. I've adjusted and adjusted and adjusted... You get the picture. I used to have the hard starting problem especially in the winter here in Colorado. So I rebuilt the carb, made sure everything on my ignition was up to task especially the battery and cables and I haven't had any problems since.:cool:

I agree with the others.The only 12A that should sound like a plane before starting,is the old Twin dizzy,with carbon seals.Is your ignition,and carb in good order?

I turn my key, and it starts.
To bend the key.

Because there's not even a battery in my car right now!

my car starts fights with me....

13B EFI. I turn the key to ON, wait for fuel pressure to build then crank it, it turns over maybe 3-4 times and goes. First time every time.

With my Mikuni sidedraft on my 12, I pump the gas 4-5 times and crank. Starts right up everytime unless its way below freezing, then I need to give it half-choke and no gas and it starts right up.

both my 1st gens would start right up after a rev or two.

i had a fun little procedure when i started the '83: wedge a nickel behind the choke lever (my choke system was broken), put key into on position, let pump run for a few seconds, quicly push the pedal to the floor twice, turn the key and it fired. then i'd have to babysit it until the ornery carb warmed up.

the '84 -se wasn't as fun when it was running. put key in, turn key, let it do it's thing.

My 13B starts within 1-2 cranks, everytime.

She's never failed me -- turn the key, 2-3 revolutions and she's fired and running like a champ. It doesn't matter if it's 90 deg F out or 15 deg F....I love that damn car...

im not sure what you mean by sounds like a plane, but has just started to make a noise on start ups. it reminds me of the sound of a supercharger, but i definately dont have one of those. i think it has something to do with the fact that my tach just started going crazy. im going to switch out the alternater with a spare i have and the if it doesnt stop im going to get the batterie checked. hopefully it will fix both problems, if not, im heading after the ignitors.

hmm i counted mine today more carefully, basically it took about 3 output shaft rotations to start (just under), I counted about 8-9 exhaust pulses before it started up.

I hop in, turn on the battery cut off switch, pull out the choke to full, turn the key rrr..rrr.rrr....choke in......rrr..rr...popp blah pft pft blah pft pft.....running.

Thats only if I've had it running in the last 3-4 days. If not, its jump start or coast down the steep driveway time.

I have a battery drain I haven't been able to locate yet.

mine is

jump in, turn key, rrrrrr...rrrrr..rrr.......r.rrr.r.r..r.rrr.r...rrr rr......click

push it down the block like an asshole and roll start it :)

Mine starts mint. Less than 0.5s crank time. The joys of FI...

Well mabey if you used a bigger battery than one designed for a LAWNMOWER, ISAAC
