NEED HELP! A/T to manual swap - Won't start

[Clem91TSIAWD]

alright,

I searched the forums and VFAQ, but cannot seem to find a straight answer. I have done an a/t to m/t swap in a 95 RS. I can get the car to turn over, but wont crank. I have no spark from the plugs. My brother thinks the ecu is bad. Not too long ago, the car did run as an auto, and the man. ecu was taken out of a used-to-be running car which sat for 2 yrs. So here is my question... do you have to put a manual ecu in the car to get it to run? (or can you leave the auto in?)...I have changed the starter, rigged it to thinking it was in park like you have to on the auto sensor, and tested two different coil packs.....so I dont know what is wrong? I think there is something more electrical i have to rig up for it to work.... but..who knows?

thanks for your input!

you can email me at [email protected] or answer back on here..whatever suites you!

Check your crank/cam sensor also..and transistor pack.

I think this might be your problem im about to do a 5-speed swap you may have forgotten this

To activate the starter circuit the 2 large black wires on the inhibitor switch must be connected to each other, just cut the two wires from the harness and soldered them together.

Correct me if I'm wrong but I'm sure you have to use M/T ecu on the swap.

I can get the car to turn over, but wont crank.

I'm sorry, what does this mean?
To me cranking = turning over.
You have three possible states. Stopped, Cranking, Running

Are you trying to say that the car cranks but doesn't fire so it won't run or that the engine won't crank at all?

It's Ok that you weren't clear, just let us know.

ok..I am not getting spark from the plugs, but the engine is turning over. I tested the spark plugs to see if there was spark...and I got nothin! I guess i am saying the car cranks/turns over but is not firing so the car will not run. I looked at the inhibitor switch, and did not see 2 black wires, but found one black wire on another switch. I grounded that black wire..and after that....i am left with the situation I explained in the first few sentences. so, hopefully that clears things up.... I also did notice a humming coming from the manual ecu after i plugged it in...wonder if that could be bad???

thanks,
trisha

 

[steve]

That does help explain the problem.

I don't know much about 2G NT cars but I don't think the ECU should hum. What does it do with the original ECU.

[Clem91TSIAWD]

I am not getting reference voltage to the coil pack( I tried two different coil packs) ....I searched a bit and found out the humming of the ecu is somewhat normal for those ecu's but only after its been drivin and mine hasn't. I am pretty sure the ecu IS working, b/c the check engine light does come on.....also i found out some people are using the a/t ecu. They say those will work, just that the check engine light stays on....and I have read some say you have to use the m/t ecu??? so i am stuck...i tried both...and still nothing.....The a/t ecu worked on the car b/c i drove it to the shop where i did the swap! The m/t ecu worked on the car, but it did sit for 2 yrs...however like i said the check engine light is coming on with the m/t ecu in the car....so i think its working....but the car still does not run!!!!!!

thanks,
trisha

p.s. all parts for the swap came out of a running car..and the car ran b4 the swap..

 

[paul s]

Are all the sensors plugged in?.

 

[Clem91TSIAWD]

as far as I know.....if not....what sensor do you think could be causing this?

Why don't you let a professional take a look at it and tell you what exactly is wrong. It might cost you but at least you'll know whats going on.

 

[eclipse95racer]

Correct me if I'm wrong but I'm sure you have to use M/T ecu on the swap.

I am about to do this swap. i have been researching it for a wile, and i havnt read anywhere that you can use the A/T ECU withe a M/T setup. i am pretty sure that you have to use a M/T ECU. but please let me know if im wrong. i would like all the information i can. i just started this swap yesterday.

I dont know too much about the 2gnt cars but my guess is that it has something to do w/ the neutral/park safety switch from the a/t. The m/t car would have a clutch switch, does yours have this switch? If not find a wiring diagram for the a/t and ground the wires for the park safety switch.

 

[Clem91TSIAWD]

I have already eliminated the park/neutral safety switch. (or so i think) Correct me if i am wrong, but if you havent already eliminated the park/neutral switch, the car wouldnt even turn over? And mine is. I just have no spark. The only other question i have is...I didnt solder any wires together. Other threads have said you need to find two big black wires on the inhibitor switch and solder them together. Well I looked, and didnt see two black wires on mine. So i found another sensor, which was not being used, and grounded it to the car. I am wondering if that is the prb? I think if you solder the wires together you create a closed circuit allowing the car to start. So, if i grouned a wire then i would NOT have that closed circuit, am i correct? Lord knows i am NOT an electrician, i am just wondering. However, why would the car even turn over if the circuit is not right?

hope that makes sense,

cirilo630 Why don't you let a professional take a look at it and tell you what exactly is wrong. It might cost you but at least you'll know whats going on.

I would rather not let a mechanic look at my car. Here in South Carolina, our mechanics only know fords. I would rather take my own chances, plus learn along the way. I just do not know much about electrical stuff. My knowledge is all in my 1g, but that is no longer used as a daily driver, b/c i have too much money in it, and it keeps breaking down. It is my when its running, weekend beat rich college kids srt's, evo's, and super charged mustangs fun car. If you lived in clemson, you would understand where i was coming from. I should prb start my own name instead of using my bf/s but this was alot more convient for now.

[staticbrainwash]

i don't know about auto 2g's but on my auto1g turbo and NA there was a TCU that controlled the auto trans. through the ecu reading. if you still have that in maybe thats f-ing things up when trying to turn over the car, because of the sensors and stuff that aren't connected to it anymore.

i dunno. just a theory.

I meant like a mitsubishi dealer. And i dont know if his town only has ford mechanics.
