Its an 89...Just did my turbo swap, got the starter in and Im cranking. Same symptoms of a flooded engine. after cranking long enough its the same thing. Should I have to do full unflooding procedures on my swapped engine?

Were going to need some details about the swap.

N/A ecu or turbo?
JDM or USDM motor?
Is the motor also a S5 (from a 89-91)?

cmanns

Why don't you?

Lol, if you jsut did the swap, pull out the plugs and check if its even flooding and if it is should add some oil or atf atleast and try to get er started

"full unflood procedure" well lets see, 10 mins tops?

RX7Club diagnosing your "swaps" issues, well lets see could take days

Its an 89 to 89 Turbo swap. Got the engine from japan2la, says tested compression.

Swap went smoothly, everything hooked up. Im getting fuel and spark.

I just tried unflooding and it didnt do much to help it turn over. Im currently looking for missed connections or something. Any ideas?

So its a JDM 13bt? Make sure that your fuel lines are hooked up correctly. Remember that the japanese do everything sdrawkcab

Off the top of my head, the fuel feed line (w/ filter) goes to the bottom hardline on the emissions rack. The return line connects to the top hardline. This is on an S4 JDM engine, but it should be the same.

Brice_Brice

Im pretty sure I got the fuel lines right. I reversed them from the USDM engine...I even followed the line to make sure.

There are 3 places to put the line down in that area. Think of them as each end of a triangle. The top one I found was charcoal canister, the bottom right is fuel in and the bottom left is fuel out. Sound right?

checking compression

btw its an n370 ecu and harness

Brice_Brice

Heres a pic of the fuel lines. Compression is good. I have fuel inlet bottom right, outlet on left and charcoal canister on top..

Brice_Brice

Any suggestions? I know you guys are smart. Heres what Ive tested:

Compression is good- Japan2la says definitely not a problem on this engine
Fuel- Getting on all of the plugs, can also hear it flowing through rail
Ignition- Spark on all 4 plugs
Air- Intake duct and all hoses connected
ECU- Grounded and tested to work by Pocketlogger
Flooding- Same ol thing, fill with ATF after cranking with fuse out and pedal down...No developments, repeat, repeat, nothing.

Engine makes normal cranking noises when I crank it...

Injector plugs are pretty obvious I believe too, is there any way I could have messed this up?
Timing? I doubt CAS has ever been tampered with by the look of wat it was.

Come on give me some Ideas, Thanks

When it's turning over, does it sound like it's trying to start at all?

Did you use the NA EM harness to do the swap? Or was there any rewiring for a TII harness?

I can't tell if the fuel lines are right, since my JDM S4 hardlines are completely different, hah. I guess they did change things on the JDM S5.

Brice_Brice

It doesnt sound like its TRYING to start, nothing but the starter cranking the engine over

I used the n370 which clicked right in to everything... Is there a possibility that the engine is incredibly flooded and I need to crank all of that stuff out for an extended period of time?

It's possible. Pull the plugs & try to clear everything out, if you haven't already done so. As for timing, a small adjustment of the CAS shouldn't keep it from starting, but it could create some nasty kickback if it was way off. A timing light while cranking would quickly answer that question.

You said you're seeing fuel on the plugs, but at this point, I would think it would be hard to tell if they're wet from gas or from ATF. I still think swapping the fuel lines for the hell of it isn't a bad idea. It's a lot easier than removing the UIM to follow the path of the hardlines to the rails, as well.

Brice_Brice

Lol well The UIM just came off...Im going to check the connections to all of the injectors and make sure Im getting fuel to the PD and Primary... Hoping Ill find my problem here.

As for the flood, Im getting a lot of ATF on the plugs now, which makes me think that my previous unflooding did nothing for me except settle with whatever was in there before...

where did you put all this atf to get it All over the plugs?..
I just throw enough to "lube up the internals".Roll over the engine and expel the rest.Keeping the plugs in Wil just foul them up.
While you have the Upper Manifold Off,follow the Fuel line from the Filter.it should go to the primary Rail
another suggetion,check the CAS and make sure it is Connected.
do you have fuel?..check to see by taking a line off.Have a buddy turn the key.it should SPRAY fuel out the Rubber line from the Filter.(Careful,,high pressure/43 psi!..get a RAG!).that is the line you need going to the Primary rail(of course!)
If it not giving you fuel and you have ruled out the OTHER hose(may be mixed up)then Check the Fuel Pump Fuse,and the Relay
I hope that may help ya a bit.

Brice_Brice

Solved the problem. I "reversed" the fuel lines like everyone said from my N/A engine... Well the fuel lines were in the same spot. I had them in the wrong place because I "reversed" them. This could be a big mislabeling problem, but we were very thorough
When they are backwards you still get a little fuel (hence seeing it on the plugs) and you can hear it in the secondaries...

RotaryRocket88

Having the lines backwards completely screws up fuel pressure, hence the no starting. A good reason to always trace the path of the fuel lines when assembling the engine. Like I mentioned before, the S4 JDM hardlines aren't even next to eachother, so "reversing" isn't an option in that case. One is above the other instead.

Not sure why you reversed them (didn't read the thread) but I had to do the same since I'm using an NA primary fuel rail with TII secondary with the manifolds. The TII FPR being on the opposite side requires you to reverse them. I'm kinda iffy on keeping the setup because of the extra bends but eh.
