i was driving my rx7 today and going down the road let off the gas an push the clutch in and it died?? tried to start it the motor was cranking but wouldnt start was at a roll so i jump started it and it ran but ran ruff ?? any one have symptoms what might have gone out??

 

wasn't right after a hard run at 26 psi, was it?

 

LOL

 

hahahahhahah anyways .... maybe list some mods so it might be easier

 

blown engine....probably have some turbine wheel damage as well. You sound like you dont know anything about rotary engines and yet your running 26psi...... yea, I'm going iwth blown engine lol

 

Well, noone needs to jump to conclusions yet, but I would say KABOOM MOTHER F****R! Sorry, but your engine could be gone. Get a compression check. That is the way my engine died, it would just die going down the road. Another question, who in the living hell runs 26 PSI on their rotary? You running methanol or something?

 

electrical

 

pretty immature posts but it does sound like the engine ...how does it idle?

 

yea why is everyone jumping on his back?

we def need some more info tho

 

i like how i phrased it better. engine implications without the insults.

i'll get all you noobs trained to talk like me one of these days

 

It wont idle and i am not running 26 psi im running 16. I was thinking it could be electrical because when i trie to start it , the motor cranks but dosnt start .. . then i try right after that and turn the key and there is nothing a cupple of the lights are flashing like the e brake light but the brake is not on ?? any one knows what it is?

 

street port 3mm seals t-78 turbo apex power fc . . just looking for what kind of fuel manigement or what

 

Sorry for my immature post, but it still sounds like engine. Get a compression check! If compression is good then maybe something electrical.

 

Another question, how did you afford an FD with all this ****? Parents?

 

yah hopefully it is something electircal i dont need a 3500 bill the car was 16000

 

so dose any one think it is electrical because if the motor was blown it would still crank over when i turn the key therefore i hope it is something electrical .. . what would do this and ware should i start checking ??

 

Damn your only 16 and you have all that **** on your fd. What do you do for a living? Or are your parents well off?

 

Do you have a turbo timer that will read the voltage the battery is putting out? If so, does it look normal?

I had an electrical issue where if I pressed the brake pedal or lowered the e-brake, the car would die. I dunno if it's possible on a clutch pedal, but maybe there's hope. Also a time where it was giving symptoms like yours and all that was wrong was my alarm fuse was blown and wouldn't let it turn over.

I guess it could be a lot of things. Electronics suck (IMO), so I'd start with the compression check before you get into all of that.

Good luck

 

i hate electrical stuff on any car mechanical is the way to go but yah i am 16 and i get all kinds of **** for owning a fd from guys on here it gets rather annoying i want to learn how to work on a rotary so i can gurantee me a spot at a high preformance shop when i get out of high school, other wise 4 strokes and 2 strokes are a breeze

 

damn it if it is electrical hopefully what should i check and how would i do a compression test on a rx7

 

How long have you owned the car? Who tuned your Power FC? << How long ago was the PFC tuned? Is it possible that your settings caused the motor to flood?

Have you checked other obvious things such as the MAP sensor? Fuses? Vacuum lines?


There is a Compression Test how-to on the 'FAQ for 3rd Gen' sticky, go look it up.

If you're still in High School, you need to take an auto shop class while they're still free.

my friend with an fc just taught me how to do a compression test on the Rx7 but if there was a problem with my ecu would it cause it to just die like that or is there something really wrong like a seal. when i try to start it I think you smell gas my dad dose not think its gas but it could be flooded

checked fuses vacumelines the all were not blown and vacume lines were still tight map sensor too.

can a rotary be running to rich that it would foul a plug? or is that the two stroke coming out in me? ? ?

 

Yes, it's very possible for rotaries to foul plugs. When was the last time your spark plugs were replaced? It's probably a good idea to replace them every 5k miles.

-s-

 

yah i may have fouled one i have never replaced them seince i got the car in october but have only put about 1000 at the most. so it could be the spark plugs wat about the ecu needing to be tuned

 

I had a very similar problem. I had a very difficult time getting my car to start. When it would start, the engine would just die while I was driving or it would intermittently shut-off and turn on (if left in gear), lights on the cluster would flicker/blink, and the gauges even went crazy on me one time while I was trying to figure it out. T-shot it down to a bad ground cable, only cost me $4 at Wal-Mart.

Initially, all the grounds checked out good (all were reading 20-40 milliohms). When I double-checked later, I noticed that the readings for one of the grounds would fluctuate quite a bit when I wiggled on the cable. I made sure the ground cable was on tight -- it was. R2'd the ground cable -- problems dissapeared. So check your grounds, and also make sure they are on tight. Good luck.
