Question about 1980 Cadillac Eldorado

Open Question

Just got 1983 eldorado biarritz, when trying to start it will catch and run perfectly when gas is put directly into the carb. But as soon as that is used up it stops. Where to start looking, I believe fuel pump is in gas tank no? Is ecm problem ? Thanks

SOURCE: engine will only keep run by pumping throttle

Hi there,

first thing to do is check the fuel flow - clean the in-line as you did and change the canister filter. Also check for any blockages / kinks in the fuel line etc. Vent opened on tank if applicable

Would the engine rev up when out of gear ?

Also check your ignition switch,check spark, fuel pump, voltage regulator,pick up coil in dist,

Let me know for further clarification.

You don't say if the parking lights and/or tail lights come on. If the rest of the lights are working. Try replacing the dimmer switch on the floor. It's relatively simple to do and cost about $15.00 depending on where you are

Biarritz. had a no start issue The ignition switch was replaced It starts now but the service engine soon light stays on when I press the gas The mechanic says the code is E52


e52 is telling you the battery was disconnected in the last X number of starts. It will probably go away after a day or two of ignition cycles. If the battery has been pulled then any other trouble codes would have been cleared and will not come back until they are re-detected, May have to drive it a bit to get any new codes to appear to help trace your problems.

1990 Cadillac Eldorado Biarritz reading shows the code e52. How do I fix?


Question
90 Cadillac sedan deville 4.5L My car won't turn over all the power is gettin to the vehicles dash tried the trouble shooting it said it was the ECM memory reset so I changed the ECM computer and it is still doin the same thing some people say it might b the saftey neutral switch but i want to no from someone with experience opinion. I have changed the ignition module and the ECM computer recently and it still does nothing

Answer
Hi Chris, The code E52 just means that the ECM lost power or ground or that someone forgot to clear the code after hooking the battery back up. It could mean a bad computor but not very often. 2 things that come to mind is a bad ignition key or lock cylinder or a faulty neutral safety switch. Try the other ignition key first. Then with your foot on the brake pedal hold the key in the start position and move the shifter slowly from P to D. If it tries to start then the NS Switch is bad or out of adjustment. If it still won't start then you will need to troubleshoot the ignition key/PASS KEY system for an open wire in the steering column. Hope that helps. Bill

Hello,my 1983 ford ranger doesn't start it does smell like gas when im cranking it over .ive had rebilut carb,cap rotor ,has good spark on new plugs ,new fuel pump,new filter and carb is getting gas.im...


That solenoid is the electric choke and it will flood the truck out if it's not working properly, have you tried to hold the butterfly opened while cranking it, if it starts then, you can unplug the connector to the choke and run it, it just might be hard to start when it's cold.

I have to use starter fluid to get my truck running and than when running it will die in idle and not restart without adding more starter fluid? what can i do?


It sounds like it's not getting fuel. Are you in a cold climate? The gas line could be frozen. You can check the fuel pump by disconnecting the gas line at the carb, you may want to put a length of hose on the line and catch the gas in a coffee can. Then have someone crank the engine while you watch to see if gas squirts out of the line. I wouldn't use too much starting fluid, you can damage your engine, pour a little gas in the carb instead. Also, on a truck of that age the gas line could have a hole rusted in it between the tank and the fuel pump. If that's the case the pump will not pull the gas out of the tank it will draw air instead. It could be the fuel pump itself. If you have a good stream of gas to the carb then the problem is in the carb. It could be the needle valve is stuck shut, take a screwdriver and lightly tap on the carb, that will sometimes jar the needle loose. If you have gas to the carb it could also be clogged jet inside the carb. I you hold the choke partialy closed will it stay running then?

BAD GAS!!! Empty tank, lines and and float. Get tarnish out with carb cleaner and put in fresh gas with chemical to dry lines of water/whatever. Replace fuel filter.

1992 Pace Arrow Motor Home 454 Chevy...not getting fuel to start


After you dump the fuel in the throttle body it will continue to run on its own or die as soon as it burns up all the fuel you dump in? Do you have access to (Noid lights)? Are both plugs attached to the distributor?
