1999 TSI1100i injected, won't idle.....

[willfanning]

I'm hoping someone can point me in right direction, i put a primer system on it because it wont start without it. starts and runs good, just sputters a bit and dies at idle. any ideas???

Welcome.

You want to get in touch with Lakeside Tech.

Requiring a fuel prime to start a Ficht engine often means the EMM module needs repair.
Continuing to start and run it without EMM repair can cause further degradation/damage of the EMM internal electronics.

Welcome! Another Unicorn owner emerges from the wild

As K447 has indicated, you likely have low injector volts. This can be caused by the EMM, but could also be a bad flywheel/stator. Here is how you can check the stator: http://greenhulk.net/forums/showthre...=1#post1532376

It's also possible that you simply don't have the correct spark plugs installed. I don't have the Tigershark plugs memorized, but the part number is likely on the flywheel cover. "Cross reference" or "equivalent" just doesn't cut it for FICHT DI engines.

Good gracious my man, where are the clamps for the fuel lines

[willfanning]

mmmmm, fuel lines were hard as a rock. I just replaced them, will be clamped as soon as i don't have to take it apart anymore.... I'll chech the spark plugs, that's a good tip!!! And, I'll do the stator check. THANK YOU for the input!!! I'll be back with updates.

OK, here's what i found... current plugs = NGK BKR5EYA, not the right plug. It calls for NGK PZFR6H.

Good, replace the spark plugs as a second step. Put clamps on the fuel lines as a first step. 25psi will likely not be held by friction alone, and can pump a good deal of fuel in a short period of time if a hose pops off...

TSI1100i update: NGK PZFR6H installed (sheesh, $14 per plug!!) seems to run way crisper mid/top response. But, still no idle..... Here are the readings that i found. 3 of them are out of spec and might be part of the problem. highlighted with the red boxes. Please let me know what you think, thank you!!

Hmm. Those values are concerning. How confident are you with your measurements?

But what is the cranking voltage, and the running voltage on the injector common wires? Should be 20VDC cranking, 45VDC running.

Can you take off the plastic cover side of the EMM, and post a picture? (This is the power board side, which produces the injector volts and battery charging from the stator windings. Looking for burned/melted areas)

Update: cranking voltage at the injector, 7.4 V on all three. Running voltage at the injector 43.5 V at all three. Also, I did a compression test cylinder one 138 psi cylinder two 140 psi cylinder three 140 psi. Here are the best pictures that I could get looking through the orange gel on the EMM.
