Sounds like the fuel pump ...yes starting fluid will start the vehicle but consider it will damage your components and you risk many internal issues especially with today's electrical components ..if a constant pressure is not maintained and a fuel pressure test can be done at many part stores to tell you the exact pressure and what it would be at {For Free} i am also considering you to check all the vacuum lines for dry-rot as this will also contribute to this issue try carburetor choke cleaner around the intake manifold and vacuum lines to see if there is a change in the motors performance ...but im nearly 100% certain you will find it is the fuel-pump ..

An 87 4Runner has a 22RE 4 cyl. engine. Check / replace the cold start fuel injector. It is a 5th injector that only actuates when starting a cold engine.
Look it up in your Haynes manual where to locate & how to test / replace.

Car will start sometimes other times i will have to continue to crank the engine it cranks everytime


As it cranks, is there white or black exhaust smoke ?? If yes, the fuel injectors have solid build up on the tips. Normally, a quart bottle of injector cleaner treats 20 gallons. Pour 5 to 7 quarts of fuel injector cleaner. With cold engine (been parked for at least an hour or overnight), while cranking engine, have 2nd person spray starting fluid into air filter. DO NOT PRESS ON GAS PEDAL !!! Let the starting fluid do its job of starting the car. Starting fluid is highly combustible, so its important you don't give any gas while its cranking and 2nd person is spraying into air filter. When engine starts, stop spraying starting fluid and give a little gas. If engine begins to die, immediately spray a little starting fluid again. When engine begins to run, let it run a few minutes to let fuel injector cleaner to do its job (loosen solid carbon build up on tips of fuel injectors).

Vehicle starts cold but runs only for about 45 seconds, then dies. No reving just before it dies. Subsequent starts die immediately.


SOUND LIKE PROBLEM IS IN THE FUEL SYSTEM AND TIMING OFF.CHANGE FUEL FILTER HAVE FUEL PRESSURE CHECK.IT SHOULD RANGE FROM 34 - 40 PSI AND 53 - 59 PSI.SHOULD BE NO LOWER.IF FUEL PRESSURE GOOD.HAVE TIMING CHECKED.MAKE SURE PLUGS + WIRES GOOD ALSO CAP AND ROTOR.HAVE INJECTORS CLEANED.ALL THIS COULD CAUSE THE PROBLEM YOU HAVING.

Check ur battery, check the engine radiator hose and the condition of radiator, and always check the water. if the problem is still there check the igniter plug if there's carbon presence around, if u found its burned, its better to change. do this troubleshooting first. it will do to trace the proble. k good am

1987 Volvo 240 DL Starts runs briefly then dies


your injectors arnt opening make sure that your white relay is good check grounds clean off the battery post. whats happening is your cold start injector is spraying a little fuel in to get it going and it is running off of that.

87 ford ranger wont start without starting fluid


It sounds like you aren't getting fuel out of the cold start injector... remove the injector when engine is cold and switch on ignition... you should get a fine spray pattern for a few seconds... if not then there is probably a problem with the cold start circuit (Temp sensor fault), or the injector is faulty. pull electrical connectors one at a time and look for corrosion... Hope this helps...;-)
