my 1987 alfa romero was parked for 8 years when I bought it it was running great when parked man had cancer now it it starts for a second then turns of I repaced injectors fuel pump ing gas fuses but wont stay pumping
you L-jetronic spider fuel pumps only pump when:
cranking the starter
when the engine is running.
you have replaced pump, injectors, fuses (which fuse? the fuel pump fuse under the rear shelf?) and fresh gas
It could be you are starting for a second or two just on the cold start relay (CSI) and the main pumps are not actually working.
I would check the fuel pump relay, under the rear carpet shelf, and the fuse connector there too.
(the big black relay as well as 8A fuse connector for fuel pumps is shown here: https://www.alfabb.com/bb/forums/7569938-post5.html
you can remove this relay and jump the relay socket between pins #30 and #87 and then try to start. That tests the wiring to the pumps....if it starts and runs the relay is at fault.
if that is not the problem, check the FPR (fuel pressure regulator): remove the small vacuum hose on top of FPR and check for signs of fuel in it....there should be none. Test also that hose is good, not ripped.
