AZ stranded!

well i seafoamed my 7, rougly 33%in gas, oil, and AWS vacumm line into dynamic chamber. did this then killed the engine a min after seafoming, waited 5-10 mins and now it wont start, will crank(rotate) no start though. i thought the seafoam "flloded" the engine, so removed plugs, EGI fuse, and cranked for 5 seconds at a time untill the battery was dead (about 12 cranks). hopefully after my battery charger does its thing it will start so i can get it out of the middle of my slanted driveway blocking people,and the HOA says no parking on street, so i cant push out of the way.
has anyone had a problem like this with seafoam?

From what I have read of other rotary owner's experiences with seafoam, I'd get it out of the engine ASAP. A friend of mine blew his turbo rotary when using sea foam.

The only recommendation I can make is to do a compression test and check the health of the motor.

i changed the oill, the spark plugs are fouled, there is spark through the plug wires on the trailing coil but not the leading. if i get new plugs and wires and put them on a dead coil will it ruin the new plugs and wires? should i get a new ecu and install it? should i get a new coil also?
it was running fine yesterday.

i did some research, not alot. my uncle and several friends use it but they dont know anything about rotorys or have one.
i did a compression check and the numbers were the same as 3 weeks prior, ~87 ~87 ~87, ~87 ~87 ~87.

Yeah, I keep telling people that Seafoam is great for rotaries, but just dump the **** in the tank, keep it out of the oil, and don't try to get fancy by sucking it in through vacuum lines and **** like that.

they say to put it in the oil but change it 100 miles after you do. cause it breaks it down.

ive noticed now if im accelerating ~2/3rd throttle in 2nd gear with rpm just passing 3k, if i release the throttle and depress the clutch imediatly the rpms will continue to climb ~500-1000rpm, for a split second, loike i still have the throttle depressed.
has anyone heard, or expierienced anything like this. my guess would be the BAC.
