Everything seems to be working except the fuel pump and the key start. No power to starter relay and nothing at the pump.

Did you put the fuel relay in it's socket?

It's in the trunk, and there's another on the right hand side of the dash area, to the right of the glovebox, and up a little.

When i did my swap a couple years ago, I accidentally pulled that relay, and put a different in it's place sometime after that. Caused me a few funky issues, such as priming the fuel pump when I pulled the dimmer switch, with the ign off, indeed, keys weren't even the lock cylinder. Thankfully, a member here asked about the fuel relay, reminded me that I'd took it out, and put one back, checked it out, sure as hell was the wrong one.

You...umm, did ground your eec with the one small black wire that pigtails out of the EEC bundle, correct? Takes a little green 7mm (if I recall correctly) bolt...

Wait....some people have had an issue with the eec not "telling" the fuel pump to power up. 88turbo had some problems swapping his '88 TC to 5.0, and I think that was part of his problem. Might shoot him a PM and see if he has any helpful info...

Start Sig to the starter relay comes from the connectors on the drivers side by the brake booster.

Does an IRCM ring a bell!!! The TC uses an IRCM and not a separate relay. SO!! power up the FP from the ALDL connector and see if it runs. If it does check Pin 22 on the ECM and run the Pump from there. If it runs check to see if your FP signal is at that pin.

The DA1 has the FP output on PIN 22 Same as the LA3. So the pump should rin if the ECM is working properly, Once again check it from the ECM and if it does not run from that pin you need to check the IRCM. Once again the TC uses an IRCM not a separate relay.

NOTE make sure the inertia switch is not tripped. And that the NSS or clutch switch is checked out for cranking issues

IRCM is not used in the 5.0 swap Tom, what I found was that my EEC relay needed another ground, I added another wire and all is well.  I found this by probing the relay connector with a test light and it clicked on with the key on.

That is good info. Witch brings another question. With the auto to manual swap there wont be a nss? Or will there still be a safety with it? This is all great info i was lost and might buy a sport harness. Or has the mustang harness been done?

The stock IRCM can be used with no issues. Dun it many times. Why would it not work. Also sounds like the no crank is a missing NSS.



The original IRCM can be utilized with the swap. Simply by a pin out of the 5.0 harness to the original IRCM if desired. Grounding the FP enable lead will operate the external FP relay if you desire. Or wire it to pin 22.
I must be missing what you are saying and how you are converting the system. Thanks

Well to be honest i am confused and lost now. I have a DA1 with a 88 stang harness and a 5.0l i hooked up all the connectors and wires and lights work buzzers work so it seems to be close. Just no fp and no start with key. How can i help you help me? This is my 1st tbird not my first wiring job so i am ignorant to the acronyms and abbreviations which i am sorry for. Where can i find diagrams to help me pin out this and get some fuel? Also if there never was a nss what would be the fail safe in its place?
