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

You need to take a step back, put the tools down, put the wallet away, and think things through.
-How do you know your injectors are stuck? -Why don't you put a fuel pressure gauge in the system to make sure that your pump is getting gas where it needs to go? -Why don't you use Spoke's testing method to see if the injectors work? -Trace out your fuel lines from the tank to the filter, to the pump, to the engine, to the FPR, back to the pump and back to the tank. Sketch it out on a piece of paper - take a picture of the sketch and post it. From Cap'n Krusty: "Outlet from pump (D) to rear end of right fuel rail. Front end of rt rail to cold start valve on 1.7/1.8, and from there to the front end of the left rail. Rear of left rail to fuel pressure regulator, regulator to Y at fuel pump. The "Y" has a short hose to the return port on the pump, and the 3rd leg goes to the tank. " Listen to the advice people are giving you - it'll get your car on the road much faster than randomly doing things. Anyone close to this person to help out??? Where's that member map?? |
