• The fuel pressure is instantly 39psi with key on. Turn it to start and it drops to 38psi and maintains during idle. Snap throttle and it jumps to 41 psi and immediately returns to 38psi.

• No codes at this time.

• The plugs look good and only have about 2000 miles on them. I'll get a spark checker as well. Is this checker you speak of the little thingy you put in line with the plug or does it fit over the wire like on a meter.

• The run-on continues for 4  or 5 seconds as opposed to 2 seconds and the clicking is a quick series of clicks for maybe 2 seconds almost like what ever it is, is sticking.

• The other noise I hear from the fuel rail/pressure regulator?, sounds like liquid or a combination of air and liquid being forced at a reasonable pressure thru the lines at a high rate for 4 or 5 seconds, then it slows for just a fraction of a second and abruptly stops. Coincides with the pump run-on.

• Could the regulator be bleeding air in to the rail? I guess it could be coming from anywhere along the supply line that has a joint as well. I'll have to investigate this thought further. Any in-sites here?

• What should it cost to have the injectors balance tested by a reputable shop or dealer?

• Unfortunately I was in a busy parking lot at the time and didn't get to pay attention to the tach. I will certainly watch if it does it again. I hate intermittent problems

• I drove it last night and today and it ran absolutely perfect. which is scary in it self, LOL, but perfect none the less. I don't like being stranded all that much myself , but it's not the end of the world to me as I am kinda use to it once in a while, with all the old cars I have but my wife has a fit if we are stopped somewhere because of the car. Y'all know how that is I'm sure, most women just don't appreciate a classic car and that this is all part of owning them.

• I really appreciate all the help. Y'all are great folks and this is a great place and I appreciate your time spent addressing my problem. Aren't cars/Vettes great? ....My bald spot is growing.

yup, sounds real familiar to that thread. I still haven't figured that out. I can't get it to do it again. Kinda makes me wary of drivin' it.

Don't give up, the answer will come. Cheers

Well, it died this morning. Went out and started it up, did just fine, fired right up. Pulled it forward so I could get my truck out and it died. Now I can not hear the pump run. Turns over but no start. Pump does not come on at all. What do you all think that loud clicking under the hood was? it was quite loud when it happened. I heard nothing today it just died. I guess I'll start with pulling the pump out and check it with the battery and see if I'm getting power. If it's the dang pump that makes the third pump in just over a year. Something is up! The clicking has me wondering. It was a quick series of loud clicks. Just didn't sound right. Where exactly is the fuel pump relay located?I'm confused...which ain't hard to do. Cheers
