ok.  so this T. were messing with has the tr6 an well.  we were having issues so. decided to pull it off.  an  go back to the stock ignition
so installed stock ign an. now it fires an dies just as. fast manually opening the throttle doesn't help  any ideas why it would start great with the. tr6 an not at all.  with the stock coil an module,
We. tried 3 different modules an coil packs annn with the same result?
all fuses test ok   injectors are. pulsing   fuel pressure isn't a problem    this is a fast ecm car   if that helps

General Buick Tech / rapid flashing ses
« on: August 06 2020, 04:25:00 PM »
so my sis light rapidly flashes with key on,   so I unplugged the ecm power wire   then reinstalled it an it went away.
my question is. this happens randomly   the ecm is a modded one. an the chip is a tt 5.7    I looked at the socket it appears ok. an I didn't see any bent prongs on the chip,


on a side note the car also randomly. dies like the ign is turned off while cruising or coming to a stop


ya think this is related an. what do you recommend I do to fix this?   
thanks

General Buick Tech / tip an stumble?
« on: October 23 2016, 09:19:54 PM »
ok  i finally  drove my car  tonight...
so far  it  stalled  twice  once while off throttle cruising   coming to a stop,   an the second time  it started to run rough  then just shutdown?  no codes  on scanmaster
ok  now figure i better get close to home  so on the way  home i  step  into it an it  almost stalls,  hmmm


ok home in driveway  rev it up a bit an its like theres a   flat spot in the throttle if that makes sense?  starts to rev then nothing almost like  when you have a   4 bbl carb  an  the secondaries open too soon...


the only thing   ive changed  is the 4inch maf pipe  the translator an the 3.5 maf meter ..
ideas  lets  have em boys....    before the snow comes lol

General Buick Tech / starts an dies
« on: October 09 2016, 06:39:29 PM »
ok so we got the new motor in  still a 109, 
wired it up
go to start it an it fires after a bit of cranking an dies immediately ??


heres whats been hacked out of it
ac ,   heater box, wiper motor,   cruise control, charcoal canister,   power master.   an the temp  sensor on the top of the intake it   broke off  so   not wired up..  think thats all i see missing..


so far we tried a  new battery,   coil pack an module, crank sensor.    added   a ground from block to frame,  cleaned an tightend  grounds at back of head. 
all the sensor reading look ok   i mean for just key on type stuff.   
any ideas
thanks guys

General Buick Tech / fuel line?
« on: October 07 2016, 01:48:26 PM »
ok on the t  we've been messing with someone removed sections of the fuel line an line to the charcoal canister.
i have the line from the filter ran to the fuel rail now I'm trying to run the line from the regulator to tank ,  now the tank is  still installed an just before the motor on the passenger side are 2 lines one is 5/16   an the other is  1/4,  will it matter if i just tie into the 5/16 line?  considering thats what it is coming from the engine?
thanks
