RX7 turns over, then dies out.
http://s1383.photobucket.com/user/ca...=recent&page=1
Hello,
I have a 1986 NA rx7 and im having a problem starting the car. The car turns over and at soon it does it revs to aound 3000 rpm, then dies out. I replaced the fuel pump(and strainer), the fuel filter, the injectors, and spark plugs.
The previous owner deleted the egr and has block off plates, if that matters.
Edit 1: added a link to a video of me starting the car.

Also as Satch suggested, the switch in the AFM has been known to cause the same symptom. Try his method first since it's the easiest to test and report back.

is your AFM plugged in?
If it is not then the car will start but die..every time..UNTIL you get the connector on the AFM and the ECU can read it.It needs to see the AFM connected.

i think i'd be more concerned about the AWS port on the bottom of the snorkel that appears to be going to nowhere(spun facing forward).
it also appears it still has an AWS valve hence the 3k startup so you probably have both ends uncapped, ie a huge ******* intake leak.
but what do i know, i don't know ****.

So after looking i found alot of open valves. I plugged up almost all of them. Now the car starts and stays on for a bit, but the idle is rough and after 20 secs it dies again.

i have a strong feeling you also have leaks at the bottom injector seals and the plenum gaskets. spray carb cleaner around the intake with the engine running to find them. jumpering the fuel pump test connector may allow you to keep the engine running by feathering the throttle.

spend the time and do it right or just pour some gas on it and let it burn is my advice nowadays. pick up the proper caps, replace the injector grommets, verify the intake gaskets were cleaned properly and are sealed well. i've seen plenty of half assed gasket removals cause massive intake leaks, this all is like $50 in parts, and peace of mind is worth the effort.
but then again i'm already disgusted by why so many people feel the need to remove emissions when it plays an integral part to engine function and even power. stripping an engine like this is what created these problems in the first place, yet my warnings continue to go unheard. sure, ditch the cat but leave the rest.
if i offend anyone by saying it, too bad.

so I just ordered the intake gaskets(both upper and lower, why not?) and the lower injector grommets. I don't really know how to jumper connections but ill give it a try after the parts come in. Due to work I wont be able to do the work till this weekend.
hopefully that'll get me closer to having this baby up and running.
side note: as I previously stated, the previous owner did the whole EGR delete. I wouldn't have deleted it if it still had the system.
