Thanks guys for the rapid reply.
Here is the situation. When it won't start the air flow sensor will slap up and down rapidly and sound like a bad rattle. You might get a momentary start but it will stop almost instantly. I've notice a cloud of white smoke form the exhaust if I really try and gun it. It's not oil color or smell. It is very intermittent and will happen cold or hot. It will happen when first started or after being driven for a while. The last time, before this one, it happened it started fine then about a mile into my trip it stalled out several times and then would not restart . I tried restarting it 10+ time and nothing, just bad rattling smoke and stalling. After about an hour, my wife came and got me and we went to several shops, we returned and it started right up and we drove it all the way to the shop. That is when we replaced the plugs and wires. The previous time it died on the parkway and I had it towed. That time we replaced the overload and fuel pump relays.
Could it be the black relay, below the fuel distributor, showing on the left center of the picture? If so what is it one called and is there any adjustment of it?
