General Buick Tech / T-Type is overheating

« on: October 04 2022, 08:29:29 PM »

Good  evening , my 87 is whipping my but , I have good flow in the radiator, fan  is coming on when it reaches temperature, every time I take it down the street about 2 miles it gets up to 240 degrees , I have one single electric fan , it comes on with the ac and when I turn the ac off if it’s at the right temp the fan stays on ! Should it be at a higher speed when the ac is on and the temperature is high ? Please help any recommendation s will be greatly appreciated!

General Buick Tech / no injector pulse

« on: August 29 2022, 06:04:55 PM »

hello guys , i recently purchased an 87 t-type that had been sitting many years from a friend . i changed the plugs , wires , fuel pump assembly and put new fuel and i cleaned the fuel injectors , to my surprise it started right up for about 20 minutes at idle good oil pressure , fuel pressure everything was looking good then it just died and wouldn't crank back up . i waited 10 minutes and it started for about 10 seconds and died , so i gave up went to eat came home and gave it 1 more try , it started for about 20 seconds this time and died and hasn't started since . what i have found is i have spark  , and plenty fuel pressure but no injector pulse . i followed the trouble shooting for no start and i keep seeing i should have 6-9 vols when checking voltage at the crank and cam sensors well i'm only getting 3.9 volts , also i did the check where you jump cam shaft sensor and put volage to pin c momentarily at ignition modue and the light at injector flashed everytime , heres where i get lost it says unplug cam sensor and jump b and c pins then momentarily jump b and c at crank and injector light should light up well it doesnt ! i ordered a new ecm but now im second guessing that it could be crank sensor , cam sensor or ignition module , im not worried about ordering the ecm i figure it will be good to have an extra laying around . PLEASE HELP and THANKS IN ADVANCE !
