This is actually to be expected to a certain extent with these cars, since they are designed to inject a small amount of oil into the combustion chamber to cool and lubricate the seals. When the engine is shut off the last bit of this injected oil does not get burned off, and just sits in the combustion chamber. It is then burned at startup along with freshly injected oil, giving a "double dose" for a second or two. I would be more concerned if, after sitting a while, the motor DIDN'T produce a little blue smoke. Now if it looks like you're fogging for mosquitoes, I'd say your rebuild wasn't a complete success, but as long as the smoking stops within a few seconds, I'd say it's OK. I totally agree with the above answer... I've owned 2 RX7's and the both blew blue smoke at start up. ZOOM ZOOM!!!!!!!!!!
Ditto. I own one with 63,000 miles on it and it does it too.
my 84 rx7 has 160,000 miles and does it aswell and she still runs stong
these motors, 12A and the 13B, have an oil metering pump that injects oil into the rotor housings every time you use the gas pedal. so the more that you pump the gas the more oil that is injected into the housings. its to help all the seals and apex seals to live in the harsh temps in a rotor motor.(long time rotary driver and racer) thanks
If you are saying the engine starts and runs for 15 seconds and dies and then starts again for another 15 seconds and dies . . . the distributor seems to be doing its job. You might want to check if there is a fuel restriction somewhere (filter or pump).
if it starts and runs for just a few seconds then dies it is generally a carburetor issue. clean or replace the carb and that should solve your issue.
It's probably your IAC.
The contour warm air blower starts on a timer 45 seconds after the burner initially starts, not on temparture
1991 mitsubishi eclipse 2.0L starts 2 to 3 seconds later shuts off
change fuel filter

If it starts and stops within seconds and after a few minutes starts again only to stop again, the fuel filter is probably clogged,
It is the VANOS working in conjunction with the cold start injector... once your engine reaches that proper temp, the "shaking" goes away.
Engine keeps cutting out. I turn the key off, then turn it back on in about 30 seconds and engine starts easily. but will continue to stop after only a few miles.
Q.Your car starts then seconds later it shut off what wrong A. that must be some crappy car
IS THE CHECK ENGINE LIGHT ON? IF SO, DOES IT HAVE CODE 0420? IF THE CATALYTIC CONVERTER IS BLOCKED, THE ENGINE WILL RUN FOR A FEW SECONDS AND STOP BECAUSE THE EXHAUST BUILDS UP TOO MUCH BACK PRESSURE.
If the key is in the on position and the engine is not running, the fuel pump is off. If the engine is running then the fuel pump is also. During the start cycle the pump will only run for 3 seconds unless the engine starts.
A bad relay switch could be the culprit if dash lights remain on after engine starts in a Toyota. Cold weather can also cause these lights to stay on after the engine starts.
I recommend just getting a rebuilt engine reinstalled. It will be cheaper. For starts the entire engine harness and computer will have to be changed. The transmission also will probably haveto be changed or adapted to handle the 5.4L. The motor mounts and radiator are different also.
Your 1991 4.3 S10 starts for about 3 seconds then shuts down because it is faulty. Take it to mechanic to have it checked.
The one that never starts its engine.
Crank the engine for about 10 seconds with the accelerator all the way to the floor, after 10 seconds release the accelerator while continuing to crank the engine. If it starts to sputter (firing sporadically, keep cranking until it starts or 30 seconds total. If it doesn't start, wait 30 seconds, so the starter doesn't burn out, and repeat the procedure. Resist the temptation to push on the accelerator as it starts to sputter. If the engine is cold, it may take 10-20 attempts before it starts. You may run the battery dead during the procedure so be sure you have a charger or jumper cables handy. If you notice the cranking getting weak, charge the battery for a while before trying again. A weak cranking will reduce the likelyhood of success. After the first time this happened to my RX8 I learned to just hook up jumper cables, to my other running car, from the start to avoid running the battery down before the engine gets clear and starts. Once started, be sure to let the motor warm up before turning off. This condition typically is caused by turning the engine off before it has warmed up. Especially in cold weather.
that the engine has nitro power which goes to the engine. when the engine receives the signal the engine starts to work
If you don't start the engine, electrical power is only sent to the fuel pump for a few seconds after turning on the key. That often makes it difficult to trace down the problem. If the engine starts, the fuel pump will remain on, but there is no need to be sending fuel to an engine that isn't running.
