Ok guys I really need help here. I just finished the auto to manual swap on my 1993 FD and the car will not start. It cranks but wont turn over. I am using a auto harness with auto ecu. I am getting a hold blinking light. when I turn key to on. I hear the fuel pump relay click but do not hear the pump buzz. If i spray Carb cleaner in the Throttle body the car runs for a sec and shuts off. So I know i am gettin spark. But seems to get no fuel..

Thanks in advance. Can the ground wire under the car being broken cause no fuel?

 

What ground wire are you referring to? Also make sure that your black wire that works the injectors is connected right.

Have you verified fuel pressure? Start there first.

Also go buy a $25.00 set of node lights from Advanced/Oreilly's etc and there will be one that matches the factory fuel injector clips. Plug the node light into one of the primary injector clips and make sure it is getting signal. If you are sequential this will be a huge pain in your ***.

Also recently had a customer with similar issue. He forgot to ground one of the ground wires by teh ECU and the injectors wouldnt fire. Simple fix, and hopefully yours is too.

 

I don't know the process on FD's, but the same problem occurs on BMW's if you don't let "think" the engine ECU that the shifter is in neutral or park position...

on the BMW's you have to ground an engine ECU input...

it's a complete other car, but maybe it will help you...

 

i have an auto FD and and in the process of buying the 5 spd swap other than this not starting issue was the swap easy to do ? did u use your auto gauge cluster as well??

 

Yeap, look at wiring diagram B-1d the clutch and neutral switch (cpu 1q and 1r) provide ground inputs to the ecu. I would just ground them for starting but not for everyday driving. They feed the idle speed and pressure regulator control. Best of luck...let us know how it goes.

 

Ok Guys! Got it running so far. I guess it was really low on fuel. I just had to jumped the wires on the diagnostic box for a minute to get the fuel primed. Im also running a manual ecu right now if that makes any diff? I also dont even have the clutch switch wired. and it still started right up. But we'll see I hope to drive it tomorrow after the rest of the exhaust is hooked up.

 

I posted a thread years ago for those interested in doing the swap and wanting to keep the auto wiring harness and auot cluster. All you have to do is jumper two wires together, the "wiring" takes all of 3 minutes to complete on the swap.

 

Do

Do you Have the link to your thread ? But yea I had to jumper a spade terminal on the big tranny connector off the auto engine harness. And it started right uP.

 

What that hold light mean anyways? It's blinking on me while the car is on.

 

the hold light is from the auto , im assuming you kept the auto cluster , its just for the lower gears on the auto tranny if your manually shifting it
