1985 cadillac eldorado only starts and runs after priming throttle body

SOURCE: 1987 Chevy Suburban 350 2wd not starting or running right

What size engine do you have in it? And, how many miles on it?? Well, I guess it really doesn't matter. At first thought it sounds like you are experienceing a fuel problem, and changing the throttlebody didn't solve your problem. I would start by looking and checking my fuel delivery system. The fact that you had to spray gas into the throttlebody tells me that fuel is not getting there. I would start with the least expensive thing to fix first. Check your gas filters. These are often , OFTEN, overlooked as a sorce of problems, and are rarely changed and often overlooked, and are the problem alot of the time. If that dosen't cure your problem check your fuel pump. Make sure it is delivering the proper pressure. I would bet your problem would be solved, but if it's not then next I would check the electrical components of your fuel system.

SOURCE: engine wont start without priming with gas first, then runs well

i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.

SOURCE: how to remove door panel on a 1985 cadillac

Very easy! One tool that will save you a lot of headache and anger can be bought at any auto parts store and looks like this:



You use this tool to pop loose the plastic fastners that are attached to the door panel edges.

But first, remove all screws...remove the door handle cup, pop loose the master door/window stich assmbly, etc. Very simple process....takes less than 10 minutes.

Door Panel

1. Remove all door inside handles.
   
2. Remove the door inside locking rod knob.
   
3. On styles with door pull handles, remove the screws inserted through the handle into the door panel.
   
4. On styles with remote control mirror assemblies, remove the remote mirror escutcheon and disengage the end of the mirror control cable from the escutcheon.
   
5. On styles equipped with switch cover plate in the door armrest, remove the screws securing the cover plate, then disconnect the switches and cigar lighter, if so equipped, from the harness connectors.
   
6. Remove the remote control cover plates and remove the exposed screws securing the cover plate to the door inner panel.
   
7. On styles with integral armrest, remove the screws inserted through the pull cup into the armrest hanger support. On some styles it may be necessary to remove the screws behind the armrest deflector or courtesy lamp remote control cover plate. On styles with armrest applied after the door trim installation, remove the armrest to door inner panel attaching screws.
   
8. On styles with with two piece trim panels, disengage the retainer clips at the front and rear of the upper trim panel. Remove the upper trim panel by lifting upward and sliding slightly rearward to disengage the the front door inner panel at the beltline.
   
9. On styles with electric switches located in the door trim panel, disconnect the wire harness at the switch assembly.
   
10. To remove the lower trim panel, remove the attaching screws along the upper edge of the lower trim panel. Then starting at a lower corner, insert a pry type tool between the door inner panel and the trim panel and disengage the retaining clips down both sides and across the bottom. On styles with courtesy lamps or reading lamps located in the trim panel, disconnect the wire harness at the lamp assembly.
    
11. On styles with one piece trim panels, remove all the clips around the perimeter of the trim panel. Push the trim panel downward and outboard to disengage it from the door inner panel at the beltline. Disconnect any courtesy lamp wire harnesses, if so equipped and remove the trim panel from the door.
    
12. Installation is the reverse of removal. On styles with adjustable trim supports at the beltline, the door trim panel can be adjusted in or out so as not to restrict door window operation

SOURCE: I have a 1996 GMC Jimmy. Fuel pump replaced (new)

yes, there is a relay, probably in the engine compartment battery relay box. If the relay fails, oil pressure will allow the pump to run, so the relay is likely to be your problem.

SOURCE: 1989 mustang gt 5.0 fuel

Was looking at posts and other sites. I take it that some relays are even under seats. Anyway, Apparently the ECU relay and the ECC relay are linked. When properly operating the ECC brain sends a signal to the ECC relay and the ground wire is tan/green. The brain can be throwing the signal and the relay terminals are not receiving the signals, so the relays cannot switch.

Although you have replaced some relays, you need to check your plugins for these 2 relays.
