So on my 74 2.0L D-Jet, my car normally behaves this way on cold start:
1. Starts right up and idles high while cold 2. As it gets warmed up, the idle "hunts" between 0 RPM and 1200 RPM and can occasionally die when pulling up to a stop sign (you might have to blip the throttle). 3. After she warms up, she idles perfect at 900-950 RPM. The problem: 1. Car is warmed up driving to a store (idling perfect 900-950 RPM) 2. Go into store for 30 minutes 3. Start car (starts for a second but then dies if you didn't give it any gas) 4. Turn key off 5. Turn key right back on and it doesn't want to start (just cranks). But if you give it gas while cranking you can get her to start....almost like push starting the motor and popping clutch). Note: My fuel pump is in the front. Stainless steel lines in the tunnel. Am I still experience vapor lock? Failing CHTS (also related to idle hunting) Other? |

Doesn't sound like vapor lock. Vapor locks usually occurs while driving down the road in hot weather. Your pump is in the front too.
When is the last time you had a tune-up? Points and Plugs? |
