Last night while waiting for a dollar menu double cheesburger @MCD's my car start to do the sput put put sound then I place in gear and started to pull off ...and BAM she died. So I tried to start her up again....she cranked up but then died again. It did this several times, and died each time. So then I let it sit for a while and she cranked right up. I raced home as fast as possible so I could trouble shoot. The only thing thats was appearently wrong was my coolant was low. But the wonderful pain in the *** add coolant buzzer didn't come on. SO I added coolant and no problems...but it's still because my coolant level wasn't that low. Now today I drove to work and no problems what so ever....ANY IDEA"S OR WHAT?

Thanks

could have been mild flooding.....or a faulty connection in there somewhere....it could be several things. I would just start with the basics....fuel, air, spark....you need all three of these so I would do the basic checks. Get a Haynes manual if you do not have one already and read the hell out of it......

Double check all your connections too....sometimes a wire just wiggles enough to lose contact for a second....

 

for some reason outa no were my car will flood over night to, but my sparkplugs didnt have any nub let on em, i had a full tune up sence, you might want one to.

 

could it have been a bit of bad gas or water in the gas?

 

So it starts up like a champ when cold and idles well ?

 

the 86 Rx7 has a bad fuel pump there is a valve inside it that keeps your fuel lines pressurized well this valve is no good it causes them to flood. most people just remove this valve but be careful if you put the pump back together wrong it will starve the engine.

Also another reason any Rx7 will flood is if you have bad injector o rings.

A quick fix while your sitting in the drive thru is to disconect the injectors (white connection next to the crank angle sensor) turn the engine over a few cranks and then reconnect the plugs and it should start right up.

if it turns out that the pump is not your problem it will be some day they all do it eventually.

 

A faster and easier way (for de-flooding) would be to just remove the engine-bay fuse "EGI", and crank it over for about 5 - 7 seconds.

 

thanks everyone.....yup I did all that everyting seems to be fine right now..but we'll wait and see.

Thanks

an even quicker way is to unplug the fuel pump relay under the dash to the right of the steering column. then try and crank it while it is unplugged...it should fire up. but if not do the harder longer unflooding procedure

 

the FSM says that fuel is cut when cranking at WOT so there is no reason to remove the EGI fuse. For an S5 at least. I have not tested this, since I have an S4.

 

i can hold my foot down all damn day and itll stay as flooded as it was before but if i go pull the EGI fuse cranke it for 5-10 sec then go put it back in shell start right up

 

s4 does not have that built in, s5 does.

 

I haven't heard of this valve in the fuel pump. Tell me how to remove it.

 

That's because it doesn't exist. One post you probably want to ignore...

 

Thanks for clearing that up.. I was skeptical about that one..

 

I had a similar problem but mine sputter while driving then died, it came up to a loose conector, check your water pump sensor connection.
