Intermittent No Start...Update #36....
Ok...I've got some time tonight so am going to replace all rubber fuel lines coming out of the tank to the metal lines...installed a wire lead from the connector up to the front so I can get a voltage when she doesnt start...
The other night I looked at the ground in the back. It was over on the passenger side of the rear next to the spare tire...a large black wire bolted to a brace. IT looked ok but I cleaned it and sanded and ran an additional from that to another spot....so.....lets see what happens now...Happy Fourth of July guys till I try and see what's next with this thing....

All right, ya found the ground- how come I couldn't, lol...
Keep an eye on the meter during every start attempt...
It won't be long- I doubt you'll make it to update #40

OK...i have not had a no start (yet) after looking after the ground but in checking the voltage tonight i noticed that it has increased from the 9-10 volts I was getting the other day to 12 + volts tonight on startup and run...looks like a voltage improvement...could this have been it?

Well..the only way I will know is to drive it for a few days and see if she does OK...could that lower voltage have resulted in not enough fuel pressure to activate injector ? I'm going to keep the voltage meter in place the next few days and monitor...like you said...

If anything, I guess, the lower voltage/ lower pressure would not have atomized properly through the injectors on a hot engine (hmmm, is THAT why we have a hot start assist system, lol...), maybe causing your problems. (the fuel pressure in & of itself does not activate the injectors- if everything electrical is working right they'll sit there and click on & off all day, they don't care if they've got 20 psi or 100 psi, but your engine will

I'd bet money that if you look a little further......that during START. the ground on pin 3D is not there for the START position, but shows up a moment later when the key is returned to ON. 3D is the pin that puts a ground on the relay in the Fuyel PUmp /Relay Resistor package which in turn gives you approx 9volts. Anyone buy into that? I do.
