Not only has no one else noticed, but no one is paying attention to you pointing it out!

haha so youre agreeing with me? nice for a second there i thought i was wrong. No intercooler will not allow the car to start correct? B/c of Vacuum leak?

No it just won't boost. What got me going is where his injectors are look at the pic GOOD! You should take some pics of the center plate i want to see where your stock injectors should be and whats there now!

Ok it's set up for 6 injectors that's why 2 are unplug in the TB elbow!

alright, took off the UIM, got to the injectors. Both are there an plugged up. took them out,and first i noticed the gas was weak.

I'm guessing dried up old gas plus new gas = fail

So looking at getting injectors cleaned, uploading some pictures, wondeiring what smoe stuff is and where it goes.

those extra injectors are ridiculous and old school. I haven't seen a 6 injector setup like that for years. I suggest going to the for sale section here or ebay or something and getting a stock throttle body inlet to intercooler plate. Ok so lets get this straight to end the confusion. You have been trying to start it with the intercooler on and hooked up tight right??


Ah thats kind of a dumb statement, tell ya what... completely remove your intercooler and create that big of a vacuum leak to the MAF and intake and let me know how your car idles and runs The best a turbo engine will do is fire for a second while its on the startup fuel map and die again, over and over again. I've worked on countless RX7's and just as equal turbo 7's and none of them will remotely startup with out the intakes (intercooler circuit) hooked up.

You said you still have the primary injectors below the intake and I can see the secondaries. If you take any of them out its a good idea that you replace the o-rings that go on them because they aren't going to seal right again especially since they are that old and brittle too. If you try and reuse them you are most likely going to have a headache of a vacuum leak and will have to pull the intake off again.

By now I'm assuming you have the FSM for the Turbo RX7's, look up how to test the injectors. They will basically tell you to wire tie the injectors up to the fuel rail so they don't pop off and turn the fuel pump on to check for leakage and then a test by cranking to check for injector consistency (fuel comes out normally and stop when you stop cranking).

While you got the intake off it wouldn't be a bad idea to clean up the main ECU ground wires that are near the primary fuel rail and bolt down to the block.

So you have pull started it and it didn't fire??

Ok so I just watched the video... Put the intercooler on! I could see someone pumping the gas while the cranked, thats not gunna do a damn thing except maybe flood it a little more. Besides you still need the intercooler on too, oh and it sounded like it wasn't too flooded cause I could here the starter working against the compression.

I took out the injectors and sending them to get cleaned out, the gas smelled verty sweet so changing it, the guy emailed me and told me he ran the toher two injectors when running over 12 pounds of boost on it.

Hello Roto

Ive been helping him try to get this bad boy running, and for the record we have tried to get this thing cranking with the intercooler on... yeah we already checked and cleaned the grounds. Its definitely an issue with the fuel. Compression and spark has been tested. So were checking the whole fuel system, and I'll post any updates..

Chris Boots

cool what a relief roto. But ya its definitely fuel related like you said. 8 years and old gas in the fuel lines can do weird things to cars. The old fuel may have caramelized a few parts like the injectors or the fuel regulator thats on there. Keep at it, there can't be many more things keeping it from starting after you guys finish going through the fuel system in it.

just out of curiostiy, what are your compression numbers? you haven't posed them so I am actually curious, because if the injectors were spaying even a little bit, that motor should have at LEAST farted

I'm guessing there is probably reasoning behind the car sitting for 8 years....

but if it has fuel and spark i still say dumpin some oil in it would start it...cuz i will guarantee the compression test numbers were low....."cylinder" wash

From what Ive seen with the car, everything is straight, car comes from Texas, says was ported by rick stiles shop down there. The he grabbed it up, did some stupid stuff to it. Look like he tried to run the six injector setup on a apex fc ( lol, thin g has **** on it ) and stock ecu. Wasn't happy with the way the engine was running and moved on to something else.

I'll see if I can get the actual numbers from the compression test.
It should of at least farted cause everything thing else check out ( coil packs, CAS, new sparks and wires, replaced all fluids) but im sure the gasoline smelling sweet ( smelled like spaghetti sauce and a little bit of gas) had a big issue on it not firing up. So right now took all the fuel rails off and pulled all the injectors. Sending those to witchhunter, and going to empty all the gas I got in there currently, then refill that sucker back up. I think that if I drain it all now, and refill it all back up, the lines should be cleared of the old crap, and the amount of new gas should greatly improve the concentration is there is anything left back up.

so got the car running thanks witchhunter, needed the injectos cleaned. The car runs now, but not smooth at all. Tyrns out it was street ported, the car stars out very rough but in hugher rpms good. It back fires a bunch as well in the lower rpms. And when I put it in neutral or the the clutch in with no gas, the rpm goes to 0 and sounds like the engine shut off. But as soon as I let the clutch out the engine starts right back up. any ideas .

test your trailing coil

Nephilim

iTrader: (1)

the coils are fine on the car, like stated with out the piggy back hks fc the car wouldnt even run. But it runs shitty with the fc, so leads to to belive i need to get the ecu tunes. Ill get aother video of the car.

So two things, car starts sometimes, other times it just cranks. Second the battery is constantly dead, and when you get a jump from another car, it discharges that battery as well.
