Re:SVO Rough Idle

Thanks Chris & Jim!
I tried 12 key cranks today, same rough cold start. However, your logic
sounds dead-on. I suppose I should check the pump pressure (it's
original '85), or try 20 cranks tomorrow!

Yes, this is what one of my fellow SVO owner friend Steve who works on
production line at Saleen suggested to me on my 1986 -- and it worked!
had similar fuel problems in his '86 just before this happened to me and
was running a fuel pressure gauge to pinpoint it -- but I didn't want to
through all that trouble and expense.) 

I had very similar problem as you but it would only run at about barely
idle for the first 3 or 4 minutes -- flooring the gas pedal made no
difference. So on Steve's advice I cranked the key about 20 times to
pressure and voila! 

It seems usually they just go out without warning. Mine had this "cold"
(meaning enough time to lose pressure) starting problem, and lack of
under boost. 

And of course there are no code readings to indicate low fuel pressure.

Now if anybody needs a virtually new bracket assembly (to convert your
early car) and 155LPH pump give me a holler!
