This is continued from the NARP board a while back. I'm still having the problem so I'm posting here
This is a carbed (dual Weber) 1.7
It happens like this:
I drive the car around town, gets up to full temp, stop at a store to go in real quick, come back out a couple minutes later and turn her over...
Crank, crank, crank, crank. Doesn't fire up
This happens sometimes, and then sometimes it doesn't happen, just fires right up. Also, the car starts fine and easily when the engine is cold.
I can't tell if it's fuel related.
I don't know if it's getting too much fuel when trying to start?
I usually turn the engine over, and step the pedal down half way and it fires up. When this no start problem happens, no matter what I do with the gas pedal it doesn't fire. Sometimes I can get it to fire by holding the pedal down all the way and cranking forever and it'll start and run at like 100rpm, really slow like a tractor. I usually try and lightly tap the pedal to get it going strong, sometimes that'll work and sometimes it'll die.
Then I can't tell if it's not getting enough fuel when trying to start -
Because If I turn the engine over and don't touch the gas at all, it won't start. I normally have to push the gas down half way for a normal start.
Or is it ignition related? Could incorrect timing cause it to do this? Dying battery? Engine seems to turn over fine. I have 12.4 volts across the battery posts with the engine off.
Or Vapor lock? My fuel pump is just below the hell hole.
Also, I've checked for any pinched fuel hose/lines and can't find any. I wouldn't think it was that because once the engine gets started again, it runs perfectly fine. I'm just scared to turn it off.
Any help MUCH appreciated. This is killing me.
