Kid puts me to shame with his mechanical skills and he can get to the tight spots easy lol . One lucky boy to be working on a ZR-1 so young .

Cool Kid! That’s how you get them started early. I wonder if his dad or grand dad are members here?

Hey . How's things .

Just got off the phone with Marc Haibeck and ordered the DVD plenum pull video and the throttle body bypass tube . Since I am draining the car by 2 litres as per Marc's instructions , I may as well install the bypass .

Also when talking to Marc and I told him what the car was doing he told me I did not have to tell him anymore info as it is definitely the FPR .

Been in contact with Phil also and once I get the FPR out I will mail it to Phil to be modded .

Looks like this will be a month or 2 process but the beast will run again .
Also have to call Jerry's Gaskets and order new o rings for the injectors .

FPR .

Mike

So you have also had this issue ? Have you replaced the FPR ? Did you giVe Marc Haibeck a call or hit up the issue on this forum ? Just curious how you got it sorted and what where the issues if not the FPR .

Thanks

hooked up the pressure gauge

and it stays at 48 psi . I did not start the engine ,only with key on .


Thanks

Tight fit but I was able to attach a fuel pressure gauge . With key on , pressure held at 48 psi for 3 minutes or so .

Thanks

Found an interesting way to drain the plenum , unless some of you guys already have done this . I hooked a small hose to the glycol fluid tube at the lowest point of the plenum towards the firewall on the right side . Then the fluid will automatically syphon out into a lower point , in this case , a measured dish for 2 litres marked so I knew how much I removed . Obviously radiator fill cap is removed or open. You will hear the fluid syphon out and just watch your fill dish level and pinch off the the hose or remove it and voila, no fluid in the plenum .

I tried using a mechanical way to suck out the glycol , but nothing was happening so then tried the hose trick and that worked great .
