RE: '86 coupe, tapping under car
Thanks! I'm still going to check the fuel pressure this weekend. If that checks out OK, then I'll see about getting the part described in the TSB. Hopefully, then, that'll take care of it.
Take care,

Sorry, but I could have probably told you that. If it is over 10 years old, GM discontinues a lot. They don't want you to fix it, they want you to buy a new one.[:@]

If you call Summit or JEGS, they may have something that might work. I would suggest a new A/C Delco fuel pump. I have one in my 86 and have no pulsation probs with it. [8D]

So I finally hook up a fuel pressure gauge to the car.The carhas an adjustable fuel pressure regulator, and the fuel pressure reads 47 psi. The needle bounces back and forth rapidly between 46-48psi. This *might* be the pressure gauge. I think I'm going to reduce the fuel pressure at the regulator and see what that does for me, although I doubt that that is the cause. I'm leaning towards a new fuel pump and "pulsator"...
