Finally... I believe I have found my problems...
1) Electrical... red heavy wires are routed to battery post. I had replaced the battery termination post with a new one when the battery was new, but not with an OEM one. I had drilled and tapped the lead and used a 3mm stainless bolt.. bad idea relying on tapped holes in lead.. it simply worked itself loose JUST by Chance..

2) Crazy fuel pressure.... I have the regulator not only plumbed AFTER the injectors, but with the inlet and outlet (regulated side) flipped...

I'll tell you one thing, Bosch sure built a hell of a fuel pump...after 30 years, its still pushing over 60 PSI!!!

....man having kids sure sucks the brains and common sense out of you..( I used to be a troubleshooting genius..) ............. I haven't changed the lines yet cause guess what... mom wants us all to take a break and go for a walk "as a family"...

Can't argue with that.. tune in next week when I show more evidence of senility and drive into a wall....

The pressure regulator does indeed go "downstream" of the injectors, Brian. Not with the lines backwards, of course...

Its at the end of the high pressure side of the fuel rails. The inlet side is the 90' and the straight out fitting is the low pressure side of the regulator.

Hi Dave,

I used you diagram to replace the hoses with all the right OEM stuff.. but I never looked CLOSELY at it.. and now maybe it will help the diagnostics

Went back and looked again... only problem is regulator is in backwards...

Will try again..

Well.. I discovered why I had the pressure regulator plumbed backwards:

I had downloaded this and printed it out at least 7 years ago. Seems it has gone through a small revision (IMG:style_emoticons/default/bootyshake.gif) (IMG:style_emoticons/default/bootyshake.gif)

I hate it when I immediately accept the assumption that I'm going senile (IMG:style_emoticons/default/headbang.gif) and that it MUST be my screw up!

Well, you know what they say about "free advice" (IMG:style_emoticons/default/biggrin.gif)

Mr Darling, I believe this is your drawing? I appreciate your efforts none the less (IMG:style_emoticons/default/grouphug.gif)

Yup, that's an earlier version that had the FPR "drawn" backwards. It was my first major revision of the diagram, and I goofed. I recall that I fixed it relatively quickly ("relatively" being the operative word), but you seem to have gotten one from when it was backwards.

Oops!

New regulator put in last night.... stunning how fast this project is progressing isn't it??

Pressure dropped immediately to a reasonable 30psi and no more "hot no start".. wow. At this rate, I'll be 50 before I'm back on the road again.

Dang Brian, you should have waited another couple weeks and rounded it off to an even year! (IMG:style_emoticons/default/tongue.gif)

Hey, progress, is progress. (IMG:style_emoticons/default/smile.gif)
