Question about 1983 Cadillac Eldorado

Open Question

Starting issues on my cadillac

I have a 1983 cadillac eldorado with v8 ht4100 250 it will only start if i spray starting fluid into the fuel injected carb. if i accelerate it want to bogg down and shut off. if i continue to spray starting fluid it will stay on. i looked inside and it looks to be getting gas from injectors. i have done alot to this car. new fuel pump & filter, new plugs, wires, cap, rotor and everything inside distributor, new temperture sensors, new map sensor, new tps sensor, check lines for air leaks. thought it was the regulator in the carb. went to junk yard and replaced it with an used one. also changed out the oil and radiator fluids, and air filter, ran alittle smoother, but same issues as previously mentioned. it seems like i am not getting enough fuel. i read in the manuel, that it might be the ecm computer..what do you think??? have spent alot of money on this car. it is werid,car was running great , then all of a sudden, it bogged down and shut off. barely made it home. i thought maybe it would be something simple like a fuel pump or distributor, but i have had no luck fixing this car. i have asked every mechanic i know. i know the car also has it own way of showing codes, to guide you in the right direction. been reading up on this. seems alittle confusing. if i could get the codes, maybe it will send me in the right direction. i have this feeling its going to be the ECM computer.

Why will it not start?

If it turns over but doesn't start, spray a small amount of starting fluid into the air cleaner input. If it fires and dies it is a fuel issue, If it doesn't fire with starting fluid it is ignition.

My 98 gmc 1500 V8 5.0l won't start. Has good spark

Spray starting fluid into the air intake of the engine, if it starts and you have fuel pressure you have no injection or injector pulse as we call it. Check ECM fuse one and two for continuity if it starts with fluid..

My 96 crown vic police interceptor, cranks won't start without spraying starter fluid.. the car won't start without spraying starter fluid into air intake hose to carb...

starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi
