on the TBI. which line is the supply? and which is the return? when i look on the back, there are two lines. I need to check the pressure and need to know which line is which

 

The inlet is the one on the drivers side. Don't lose your O rings as you take it apart
Oh and you check pressure on the return line

 

we did a few different pressure checks yesterday. All is well with pressure, so it has to be my regulator, im gona try and rebuild it this weekend. wish me luck..

btw, i discovered, your car runs like CRAP with the MAP vaccum off... lol oops but it does KINDA sound like it has one hell of a lopey cam in it.

 

Well when you test on the return line it is testing after the regulator. When you yesyed the pressure did you do it with the car running? When you rapp the throttle (and the vacuum drops) did the pressure jump hugher? After you turn the key off and the pump stops running how fast did pressure bleed down?

 

i tested it running and off. No extreme jumping on vaccume lines or anything. Everything was great, never did test the return lines though... but i mean, from being able to SEE the fuel being practically dumped in to the TBI with a garden hose, im thinking it HAS to be the regulator...
