‘74 2.0 Wont Start Options

[Jackba]

Hello,
I’ve read through quite a few posts on this subject While working through the problem but I’m still stuck. I hope someone can point me in the right direction.

This is an original car with FI. Car was cutting out while on the freeway. Was able to get it home. Weeks later I got back to it, started it and took it on a test drive. It was cutting out even worse on local streets. Got it home.

Posted on the site and the advice was to pull and clean distributor. Did that and checked trigger points ignition points and cap. Looked good. Changed condenser. Checked all wires and saw nothing out of place. Removed and checked and cleaned the board on throttle body. Very clean with minimal tracing. Hooked up battery and turned key to on 4 times. Fuel pump running. Pressed accelerator to check for 20 clicks. Then tried to start. Cranks well and catches then dies after one revolution. Tried again several times and it only cranks. Tried again and it catches and runs well for 3 seconds. This was repeated many times in no particular order.
Still won’t run.

I rechecked the static timing again and went through the same process and got the same results.

Next I plan to pull the fuel filter and injectors and see if I’m getting fuel. If no fuel in the rails could it be the fuel pump even though it runs for 1.5 seconds each time I turn on the ignition? Fuel pump is 3 port and probably original to the car.

Any other ideas are welcome.

Thanks in advance,
Jack

Pulled the tank, just to rule it out. Some debris on the lower part of the sock but nothing that would restrict flow. Also pulled the last two injectors and checked the spray pattern. Good.
Unfortunately it still won’t start.

So here’s a summary of all steps taken to get it back on the road.

Symptoms:
Cutting out on the freeway. Got it home.
After some time, started the car and drove it around the block. Bucking badly.

Changed condenser
Disassembled distributor and ultrasonically cleaned all components
Fresh grease between the plates
New points
Inspected trigger points
Centered trigger points using ohmmeter and rotating shaft. Reassembled distributor.
Set points and static timed to #1 at TDC
Attempted to start. Turns over but won’t catch and run
Checked fuel pressure: 30 #s
Checked injector plugs with Noid light. All good
Cleaned relay plate relays and contacts
Now fuel pump doesn’t run...
Diagnosed open circuit on relay plate
Installed replacement relay plate from Brad Mayeur
Fuel pump running
Changed fuel filter. Not clogged very little residue
Tried to start with starter fluid. Starts and runs for 2-3 seconds then dies.,same as with fuel only
Pulled injectors and bench cleaned with carb cleaner and 3v battery. No gunk. Good spray pattern.
Reinstalled injectors checked injector plug fit. Good and tight
Pulled fuel tank. Some residue on bottom of sock but nothing that would restrict flow.
Reinstalled tank and added 3 gallons of fresh gas.
Verified resistance at the CHT at ~ 3000 ohms @ room temp

Still won’t start...

So, I have spark, I have fuel and throttle body is clean with a recent TPS board that shows very little wear. Injectors are working. What am I missing?
