My fox starts sometimes. I've repaced ignition coil, ignition rotor, distributor cap, plugs, wires, and can smell fuel when trying to turn it over. Does anyone have any ideas? I greatly appreciate any help you guys can provide.
Here are 2 things that happened to me lately on 2 different cis cars......
1) replaced the worn cooper plugs on one car with platinum plugs, ran fine for a while.
then it started not starting cold. Turned out the platinum plugs were getting wet with the cold start fuel enrichment, so it was basically flooding/ banged in a set of new coopers, starts every time now.
2) on my own car, an 88 Fox, it would start half of the time, but sometimes not. I could smell fuel, but apparently it was not enough fuel for it to start.
In this case it was the in tank fuel pump that was dying. I replaced that, and no more trouble/
In your case, I'm getting the sense that it is somehow a fuel issue.
Oh and do you have a Bentlys yet? Great read lotsa help in there!
I actually have 2 bentleys, and have been amazing for everything but this. The in tank fuel pump and tank it self were replaced when I got the car 2 years ago, I have new coper plug less than a year old and I don't think it's a compression issue because when it starts it runs great. I will try a compression test sometime in the next couple weeks and give you guys an update.
I mean, I hope that in your case it is something simple - just saying that this sounds very familiar. Common failure mode for these 8V motors when they get north of 250K miles.
Of course, nothing wrong with Sciroccos either. Their forum here is the only other place I like to hang out, nice bunch of folks that don't turn their noses up at our lil' beasties like the MkIV forums do.
If it's hard to get it to start but it runs great when it does start, the first thing I'd check is if the cold start valve is spraying fuel when you're cranking. Remove it from the intake manifold, and point it into a bottle; crank it for a couple of seconds and see if it sprayed any fuel.
If it doesn't spray fuel, remove the electrical plug from it and try putting 12v directly to it to see if it's the valve itself. If it does work then, the chance is you have a bad thermo time switch, or wiring (plug at the starter missing, perhaps).
