No_Rotor_RX7

friday i finished re-wiring a haltech e6k. started the car up no problems, let it idle for a long while and everything was great. (motor has about 100 miles on it). left it at the shop for the weekend, come in today and go to fire it up and the battery is pretty much dead. cranked over slowly and probably flooded it out a little.

i pulled the plugs, turned the injectors off, spun it over.. put brand new plugs in and a new battery. go to spin it over and it will turn over a couple times (fast) and then back spin as if the timing is waaay off, YET i have changed nothing in the map.

seems maybe there is a lot of fuel still caught up in the chambers?

any ideas?

Usually Haltechs dont like cranking with battery voltage being lower than 10v, only with really really good compression engines you get em to start that way. But, if you were able to start it before and now with new plugs and battery it doesnt want to, something else may have been affected.

But also, make sure your cold starting parameters, ie. coolant correction, airtemp, fuel maps, timing map, etc, are dialed in properly.

Reshoot TDC to double-check it's still correct.
I've seen Haltech's lose TDC for some weird unknown reason.

that's how it is acting honestly... sooooo fuggin weird! i have absolutely never seen this happen except on 12a's when the distributor is off a tooth.

thing is, i put a little oil down the chambers and it almost fired up. it's still acting like it's super flooded and worse like i said the motor isn't anywhere near being broken in yet hahaha.

i'll try some stuff in the morning. thanks guys!

whoops, almost forgot to post the final result. i have never seen this happene but i did have to zero out the timing again. completely fuggin weird but regardless after the fact the car fired up first click without a hitch! it is now running beautifully and in the customers hands.

i appreciate the assistance fellas!

I've seen it happen a few times, and it was surprising also.

I don't suppose you're working in an area with heavy microwave or radar frequencies?
The last time this happened was because I was working on a car that was close to an airport...
