This is my barn car that has been sitting for 30 years. It is a 1970 1.7L stock D-jet FI. I pulled the engine and also the FI wiring harness to freshen up some sheathing and a few terminals. Here's the list of FI and ignition repairs/replacements done. Engine back in last month and still sorting a few things out...

The engine did run (rather poorly though) before all of the following.

-New plugs, wires, points, condenser, rotor and cap.
-New blue coil
-New fuel pump and hoses
-Added fuel pressure gauge in line.
-Fuel pressure at 30psi - jumpered fuel pump at relay to set
-New vacuum hoses
-Verified all ECU connections using Bowlsby's checklist on his site (although had no help to verify both trigger points operation while cranking - not cranking, had one side open and one side closed)
-Fuel injectors were sent out about a year ago for cleaning - were put back in and run but have been sitting since then (possibly clogged??)
-New vacuum advance/retard canister
-Static timing done and points gap set for initial start up.


The engine will turn over easily by the starter and will run for a short burst on starting fluid. I do not hear the "brrrrrrr" or "clicks" of the FI's clicking as the throttle is opened (i did verify that the TPS is connected and working while going over Bowlsby's checklist).

Are my FI's stuck or clogged, ECU dead, what else?? (IMG:style_emoticons/default/headbang.gif)

Where next?

I am so close to getting this thing on the road after about 2 years of sorting things out. I would greatly appreciate any direction.

Thanks guys!

Brian

Wait a minute, guys. He has fuel pressure. That means the pump and hoses are installed correctly. Gotta read the whole thing .........................

From what I've read, he has fuel pressure when the relay is jumpered. Do you have fuel pressure with the relay plugged in, while cranking the motor?

Thats why I asked if you tried to start it with the relay jumpered.

If you have fuel pressure while cranking, or it doesn't fire with the fuel pump relay jumpered, start looking at the injectors and their trigger circuit.

Careful reading of the thread reveals this comment: "- the fuel pump does run for 1-2 seconds when the key is turned." I read that as the fuel pump, AND the relays work.

Good point. I defer to you because you are the man.
