Need help with fule injection for 1.7 1970. cant get the fuel to the engine. tried putting fuel in every line. checked fuel flow to the pump. seems to have a little air past the filter (new) pump is sluggish after rebuilding and cleaning the varnish out. i would think yhay the pump would pull fuel to the bay right? with the engine turning over but not starting the pump runs. i do have some vacuum lines gone but the big main one is there and the distributer line as well. please help. im ordering a new pump because i just dont think it is operating as it should. thanks

I have a `70 1.7L as well that had been sitting for 30 Years. After about two years of on and off work it is a daily driver.
I had the same issues. I agree with the info posted so far. Order a VDO fuel pressure gauge from JEGS and mount it in line with the fuel hose upstream of the fuel pressure regulator. This will tell you a lot about what is going on and will allow you to instantly troubleshoot and eliminate many issues. Mine is mounted permanently between the cold start valve and the driver's side fuel rail. You don't necessarily need to replace that injector with the cracked pintel cover - it is just a plastic slip on cap, if I understand what you described. If you do know that you have fuel pressure and power to the injectors first and you know that your injectors are "pulsing" or "firing" then you'll know that your injectors are clogged and you can send all of them off to be cleaned and serviced. There are several reputable service guys - search the posts here. Stick with the hose plumbing guide that was posted from the Pelican Parts website it is the same for the 1.7L fuel lines. If you go changing things too much - it will make it more difficult for us to help you figure out what is going on and how to get you back on the road. If you follow the advice given and provide answers to the questions we can save you some time, and most importantly, money$$$$ that you can spend on fixing other problems. Hang in there. |
