Need some help: 87 cutlass supreme starting issue

[DirtyO'LgrannyGbod]

hey everyone im new to the forum and need some help..ive searched and did find helpful advice that i have followed up on but still haveing the same problems..

im a starting issue cant seem to figure it out..

1987 Cutlass Supreme Brougham rwd 305. 5.0L Bone Stock canadian 91thousand original ks on original engine..

recentley their has been starting issues...keep in mind my oil/choke light comes on when i try to start the car

so just the other night i filled up at the gas station..came home sat in the driveway let the car idle for 4mins..all of a suden the car shut off ..and wont start again..

Previouse issues just before this:
just before this i noticed the car would start great the first time..id run into the store or wherever for 6mins and the car wouldnt turnover and keep running ..it seemed like it would be starved of fuel..the only way to get it to start up and run is if id pump the gas pedal several times and it would then run okay ...

that being said i thought it was either spark problem or fuel problem ,,i leaned toward spark prob..so i changed the following with upgraded parts:
spark plugs/ spark plug wires,
distrib cap
coil
and still the same issues

but i do know the carb is getting fuel as my old man cranked the car as i was watching the fuel line to the carb gush out gas when i was changeing the carbs fuel filter
so im guesseing i can rule out the fuel pump ??

i cleared the fuel inlet leading into the fuel filter in the carb itself so i know thts not blocked with debris and changed the fuel filter on the carb itself so i know thts good



THE NEXT DAY

okay so the car does want to start somewhat!!! it will only slightley run if i press the gas pedale to the floor though and even then itl run like SHiiiiiiiit very bad slugish...only did it once didnt want to do it again..it does seem like its starveing for the fuel..i guese its not getting the right amount

is that a telll tale sign of the fuel pump is on its way to goin :?:


All help greatly appreciated

check for vacuum leaks with a vacuum gauge. if you have a vacuum leak it will barely run and will be running very lean. Also a pin hole in a fuel line can do the same thing

hi thanks for the reply..so i dont have a vacume guage tester..but i did check thuroughly all of my vac line leading to and from the carb and their all connected and fine..gas lines are fine front to back as the car was gel/oil sprayed religiously..

Check your Starter and battery cables especially then one to the starter.. change to a heavy gauge cable.. if you test it out and it runs then keep it if it still has the same issue return it.

Had the same issue it was a series of things.. choke, cables, starter, battery.

Good Luck!

thanks for the reply man..well i know its not the starter..starter is new and spins/cranks the gears with no hessistation at all sounds healthy as can be..and i know my battery is new aswell..running just over 12v on the meter

it's not a 307? if it is i would check the purge valve to see if it is ruptured. It will suck in extra gas if it is bad.
