Reply to "No gas -when starting cold"

The way to check the fuel pump pressure is with a gauge. Put a "T" in the fuel line & watch the pressure while the engine is running.

An intake leak will be more apparent when the engine is cold, as under those conditions the engine requires a rich fuel mixture. The extra air added by an air leak causes a leaner mixture. When the engine is up to temp. the engine can tolerate a leaner mixture(up to a point) so the effects of an air leak may become less noticeable as the engine warms up.

Ignition problems can also be more obvious when the engine is cold. Check your coil, wires, cap, etc.

I have also seen cases where incorrect cam timing can cause hard starting and also require excessively rich starting mixtures.

Hope some of this helps...Al English
