My car hasn't been running for the last few days and it seems i've tried all i can try. Its came down too the primary injectors must be stuck open because i get spark, and fuel but it won't fire. My question is how hard of a job is it to take out the injector? I've never done anything like this on a rx-7. Looked at the service manual but that really doesn't help that much.

should be easy with your mods.

really? how so because i lost the rats nest when i put on the single? Don't the injectors have to be set a certain way?

I dunno if it's stuck opened maybe it's just flooded. I tried unflooding it, but I didn't do a good enough job. After unflooding it again and cranking it for a while it fired. What exactly have you done.

Tried the stock ECU, Checked the coils, Checked the wires, Put in new plugs everytime i'd get done with unflooding it. Checked Fuses, Check relays, Tried to push start it. I get a lil bit of white smoke in the exhaust after i crank it. Sounds like it has compression too. So i figure its got to be one of the primary injectors.

I thought it was flooded too, but i tried that once didn't work, so i pulled the fuel pump relay and the egi fuse, cranked it 2 times for ten seconds, put the plugs back in let it sit over night did the same thing the next day three times, charged the battery new plugs and nothing. So i doubt its flooded

2 things. first that is prob not a long enough time unflooding it. did it push out clean air? a piece of paper will show any splatter of fuel that you may not see. second. it should take 20 min to pull both rails off the block and see if they are leaking under pressure with your set up. you have verified spark right?

you have to crank it 20seconds 3 times dry with the spark plugs out. Even then sometimes it can still be flooded. I would do that then have someone help you push start it. I had to crank mine for about 40 seconds before it turned on. It ran really rough so I just held the gas down till it idled semi okay.

I know i'm getting spark i tested all four wires and has new plugs in it. So what your saying its possible the car is still flooded after trying to unflood the car and push starting it. I was told u didn't need to get the car moving very fast to push start it, i had someone push me at like 5mph droped the clutch and it read 500 rpm but didn't fire. I should only have to pull the primarys shouldn't i since those are the injectors that are used for start up, idle, ect. I've tried searching on here for answers but it keeps comming back to the stuck or leaky primary injectors. Will i need new o-rings for the injectors like the service manual says, if so aren't they like $.30 from maloy? Sorry for all the questions, i'm going to pull the injectors tomorrow if it doesn't rain like it is today!

i would get the primary and secondaries out and see if they leak. leave them attached to the fuel lines just turn the car on and see if they are dripping. check the wiring especialy on your secondaries if they short it will open and flood. have you checked the compression?

The car sounds like it has compression

re_rotary7

have you checked your oil to see if it has too much gas in it, that could also be why it wont start. If you flooded it real bad its possible for the fuel to leak past the control rings and into the oil which when you try to start it and its injecting oil could be aiding in flooding it. if it has alot of gas in it, change it, put some atf in the plug holes, put clean plugs in and try again, lets hope your problem is as simple as that. try checking your boost sensor, maybe it came unplugged or took a poop on you.

Went out and tried to start it for the hell of it, and i noticed when i tried to start it when i stoped and had the key in the on position my pfc would read 12.3% injector duty and i hear this humbing noice. Then when i turn it to the off position then turn it back to the on position the humb disappears and my pfc reads 0% injector duty, is this normal i've never noticed this before?
