Re: [T3] 1971 Fastback with fuel injection, no start!


Thank you for the quick response.  Based on what you've told me it sounds like I am wired correctly, my fuel pump relay is probably good.  I guess I should start looking for a ECU that is compatible with this vehicle.  Next question is does anyone have one for sale or know of a source to locate one.  1971 Type 3 Fastback vin #311 203 9879 built in 9/70.  What other information would I need to locate the correct ECU?  Again Thank you Bob as this may be the answer to the problem I have been dealing with now for several months.
