I bought a 1992 jetta GLI w/ 9A.
After lunch on thursday the battery was dead. got a jump and drove down the road to autozone. they didn't have the battery so i got another jump and headed down the road to the other autozone. about a mile down the road the car died at a red light. we pushed it out of the intersection and got another jump. i made half of a u-turn and the car sputtered died again. push started it. and it died again.
so we got a tow to the autozone and bought the new battery.
we cleaned the throttlebody and fired it up. car ran like **** and died. hasn't started on it's own since.
basically what we've done is check fuel pressure at the distributor. (90psi)
new fuel filter just for fun.
put in a different fuel pressure reg. out of a junkyard gli.
swapped out the pressure differential
and checked a couple different sensors
we can get the car to start by lifting the flap on the fuel distributor but wont run after you let it down.
does anyone have any ideas?
