 |
|
The car was running fine then won't start. All we did was tighten the belt. We are getting 12v + to the injector but we're not getting a ground signal. The car was running fine until we adjusted the belt. Now it just cranks. We have good fuel. We tried using starter fluid and it wont fire. We have good spark. Does anyone have any ideas on what the problem might be or what we should check?
Thank you

| We got it. For some reason it flooded. We think there's something wrong with the cold start. |

Since this all began after messing with the belt the place to look is the thermo time switch (TTS) just above the lower pulley, broken wires?

Then try taking the CSV out of the loop, disconnect the fuel lines and connect them to each other with a temporary barb fitting, leave the CSV in place to fill the hole in the plenum.
The CSV only comes into play when it's really cold, if you don't drive in winter you won't really miss it. If it's sticking and dribbling it could be behind the flooding.
