Unflooding was done before every starting attemp.

Engine cranked fine.
Trying to catch on to start all the time, but no start.

Barely started a couple of times only when I applied slight pressure on gas peddle.

Will die immediately if rpm drops belows 2Krpm.


well~ Im STUCK! need help!!!! :cry:

 

TBmod requires idle recal.

Though personaly.. I think its just flooded like a ****. Hey its an Rx-7.. if it wants to flood, it will...

Oh, and after the TBMod, you'll usually have to blip the throttle while cranking. BLIP, not WOT, Tap, or anything above 1/2" pedal movement or you'll flood.

My experience with the Tb Mod anyway... friggin PITA that doesn't really give any results other than a cumbersome start and no cold idle.

 

same kinda thing happening to me the car starts revs to 2k then dies i think theres a huge vac leak but i cannot find it other then the UIM is wobbly on the LIM =(

 

Yo have a vac leak. i had the same problem.. i enged urebuilding a diff engine and then re did all the blocking off and now itz fine

 

hmm maybe i should throw some gasket sealent on the plates instead of just the gaskets.

 

Easy for you to say (type) j/k

 

Yeah~ it could be vac leak or flooded.

but I already checked a gazillion times for vac leak.

I did the unflooding procedure every single time before I tried starting her.


it might be the TPS and the bad timing... but how can I adjust them when I can even get the car running?


Plug wires connection are good.

 

The car should at least start and run even if the TPS is totally unplugged.

Did you by any chance reverse the fuel lines?

Sounds like a vacuum leak though.

 

Did you go over all the block off plates and intake manifolds with rtv and new gaskets? I Had a big vacuum leak that sounds exactly like yours, everything was checked, put rtv on the acv and the lim-middle manifold and boom, fires right up to normal, then i let it idle and warm up, set timing, set idle, set tps and she's a champ now

 

fuel lines are good.

All block off plates have RTV applied~
UIM to LIM has the original gasket on~ looks ok but stuck to LIM. Maybe I should RTV here?

 

Yeah man better safe than sorry intake leaks can cause what your saying, they did for me.
