88 RX-7 Turbo hot restart issue
 

Greetings All,
The issue I am dealing with is the car starts good cold, and if you turn the hot engine off with the key it restarts good, but if the engine is hot and you kill it while taking off from a stop, it will not restart. It will crank all day long but will not fire, but it will start while hot with a push and popping the clutch while in gear. Otherwise, I have to wait till the engine cool off. The local Mazda dealer doesn't have a clue what's wrong. So has anyone else had this problem?

What do you mean by killing the car from a start? Do you mean the car dies from an idling position to a moving forward position and if you try to restart the car you have no luck.

If you take off from a start and let the clutch out to quickly, don't give it enough throttle etc., and you stall out, it won't restart.

How often does this occur? And do you try to deflood the engine at all when it has a problem starting after dying.

It occurs only when hot and stalled as I described. With the fuel injection I haven't experienced a flooding problem. If you shut down with the key while hot it will immediately restart.

More like how often does the car die out (the 'when' has already been established)? And you were asked if you use the deflood procedure after the car dies out and I'll take that as a no, but it is definitely something which should be done.

It only happens when the wife is driving because she is not aggressive with the throttle. What is the deflood procedure? Also, either way, this shouldn't happen to a properly functioning car, yes?

If it is driver error then correct that aspect. To deflood you pull one of the EGI fuses and w/one of the plugs off of each of the housings you turn the engine over to spill the excess fuel out of the housings.

A thirty year old properly functioning car? That's a bit of an oxymoron.

The main point is, hot engine shut down with key it will restart immediately, kill it with a bad standing start and it will crank all day without starting. There must be an underlying issue.
Oh, by the way, my 66 Pontiac runs flawlessly.

The engine is being flooded, but if you want to think otherwise it's your choice.

Thank you for your help. It's not a matter of choice. The techs at Mazda can't seem to come up with an answer. They found no evidence flooding.

90% of mazda techs don't know squat about rotarys either, they think its an alien engine and are afraid to work on them, or they "try" and charge out the arse for it (rx8's when they first came out is a prime example)

I agree with satch, its flooding, but, i also agree with you, when you stall it from the clutch, it shouldn't flood. Mine has 104K original miles on it, has a bad coolant seal, has low compression, and runs rich, but if i stall it from getting to antsy with the clutch, i can hit the key and start it back up with no hiccups

Just a random thought, when you wife stalls it and goes to restart it, she isn't pushing the gas pedal when turning the key is she?? That would flood it
