I have a 1986 toyota pickup 22re engine that starts fine in temps above 20, but any lower than that, the engine starts up for 1 second, then dies. After that, the engine just cranks. The only way to start it is by injecting ether ether or gas into the throttle. It starts fine after that if it doesn't sit too long. Im pretty sure fuel is bleeding back to the tank after it sits in cold weather. I replaced the cold start injector, fuel filter and time switch. Should I try replacing the fuel pump or any other suggestions to what the problem might be? Thanks.

 

think we got her cold start time switch and re-routed vaccum on fuel regalator closer to intake not sure witch one did it....but she starts in cold temps now thanks for all the replies,,,,,,,,,,Rusted Rooster.
