Bypass the relay on pins 30 and 87 to see if it starts or cheaply enough, buy another relay (Delco).

Installed a new relay and so far so good. Keep your fingers crossed y'all. Thanks for all the help and explanations. You've all been a great help. I'll post back if it turns out different. Cheers

If the relay fixed that, you still have a problem with the oil pressure relay. You have a dual purpose oil pressure sender/relay that it is a backup for the f/p relay. It is redundant and is under the distributor. It should have a 3 wire hookup on it (a real PIA to get out, have to pull distributor to do it.).

I was thinking about that. and was wondering if the relay sticking or fluttering would over ride that and cause it not to come into play. Can you get to it from underneath the car?
Also the lead from the O2 sensor was lying on the heat shield of the Cat Cnv. and the insulation was melted, I rerouted the wire and and wrapped the bare spot. would it shorting to the Cat. Cnv. cause any problems like that?

It sounds like the car was just relying on the relay and the oil pressure switch is not working. No, the switch is under the distributor.

Yes, it would short to ground and make the car go full rich. Any black smoke @ idle?

 I figured that was the only way to get to it but thought I'd ask anyway, LOL!
I didn't notice any black smoke but I had noticed some black soot in the tail pipe as of late, so.....? It may be just me but it seems to run a little beter since I rerouted the wire.  Idels smoother and a slight bit better exceleration.
Thanks again for the help, LB I really appreciate you takeing the time to address my questions. Don't know if I can, but if I can ever help you .......
