Question about 1983 Cadillac Eldorado

Open Question

Car will only turn on with starting fluid and also only stay on while spraying carb, alittle at at time, what can be the issue?

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 , the cars wants 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. i had rebuilt the injectors and still nothing, thought it was the regulator in the carb. so i 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. when we replaced the fuel pump, we took out all the gas, and it was very clean. i read in the manuel, that the temp sensor, map, tps, speed control, all control the air and fuel...the only other thing that it might be is 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. i have also read that sometime the computer is grounded correctly, or losing connection..i am going to remove computer tonight, so i can get the serial # or part # to see if i can find one, do you think i have missed something???

SOURCE: I need to find out where a coolant sensor, map

The coolant sensor is on the front of the engine next to the thermostat housing where the upper radiator hose meets the engine.
The manifold pressure sensor (MAP) is on the firewall and looks like the picture below.
The ECM is in the right pillar to the right of the passenger's feet.
Please let me know if you have more questions.
See pictures below.

have you put a fuel pressure gauge on it if so how many ponds of pressure does it have also if this is a distributerless car turn engine with a socket see if there is slack in rotation if you turn counter clockwise 1/4 turn stop and turn clockwise if so you more than likely have a stretched timing chain or jumped time

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

Carb Floods out


Your float level is to high when you put the kit in they give you a float adjustment gauge,you will have to pull you carb back off and reset, but before you do that what is you choke set at if it wrong it will flood too,But if it set right you can look down your carb and you see gas dripping your you float is to high

My 1997 Chevy Lumina won't start, it sounds like it wants to but it wont turn over, has gas, tried the carb spray, still won't start. Help!!!


did you use carb cleaner or starter fluid. if you try starter fluid and it starts for a second and then dies you might have a fuel pressure issue. if not check for spark.

1983 coupe deville powersteering wineing


you might have just gotten your lines crossed backwards when you do a steering pump with line change out the fluid doesnt stay with the steering gear box
start vehicle after filling the pwsp.
turn wheels both directions for at least a minute with pwsp. cap off watch the fluid if lowers then its going to gear box where its required to stay the wineing is something the box does when its brand new it has to broken in like shoes propper fluid is a plus
