3.6 conversion no start, Help

[Kevin Stewart]

Hi guys well its finaly all hooked up but i go to hit the starter and nothin, any of you remember your starter wiring? i have a battery cable under the car connected and a same size cable on the harness and both are connected to the power side, then one smale yellow wire to the other side, Thanks ion advance for any ideas, Kevin

[mb911]

What year car is it in? How did you convert the harnesses? Have you tested the yellow wire for power when key is in start position? Is there a clutch pedal no start function on your car? I guess I need more info?

the car is a 82 i used instant-g's conversion, I havent checked the yellow for power, Kevin

[Kevin Stewart]

Any ideas, Kevin

[mb911]

Do you have power at the yellow lead? If not double check all connection including your ground off the tranny. I had the same problem with my project and turned out the yellow wire was on the wrong terminal. Next would be to see if you have power coming from the ignition switch.

Good luck

Check the starter solinoid connections. I put my solinoid wire on the closes to the bottom connector by mistake. It should have been on the top connection of the solinoid where you have to reach up and around to get it connected. I had to remove the starter to figure this out which was a pain.

Hello,

have you connected the ground strap to the engine?

doble check every connection against Ischmit´s wiering chart.

you are almost there

Kevin,

Make sure the transmission ground strap is hooked up. Next check ground and power to the starter solenoid (the fat red cable and the smaller ground strap).

When you turn the ignition to START yellow needs to have power. If not you have to trace it back via the 14 pin connector (pin1) in the engine bay to the ignition switch.

I made the misstake of loosening the nut of the ground strap coming out of the starter motor to the soleniod. When I tried to fire it up the first time it would turn over once very slowly (felt like a dead battery) and then nothing. After tightening the nut everything was cool.

Is, i have two thick battery cables one coming from the engine harness and one from battery, then one small yellow wire, i put both thick cables on one the the yellow on the smaller post is this correct, Kevin

[ischmitz]

Correct Kevin,

there is the cable from the battery and the engine harness cable (from the alternator). Both go onto the same terminal. The yellow cable should have a cable shoe if you have your original starter. On the 964 the yellow has a cable eye.

ok this is as far as i seem to be able to get,
battery fully charged cables and 14 pin connected right,
if i just turn the key nothin,
if I put a test light on the yellow wire and turn the key the light comes on but something under the hood clicks take test light off again nothin, any ideas on my next step to test?, Kevin

is there a relay for the starter? Just a thought.

[ischmitz]

Kevin,

check the following:

1. Battery voltage with everythinh off to be 13 volts.
2. Check that you have two red wires going to one M10 post at the starter relay.
3. Measure voltage at that M10 post to chasis. If zero you did not connect the ground strap between the transmission and chasis.
4. The starter relay has actually two M10 posts. Check the voltage between the two M10 post. Be careful not to shorten things out since there is no fuse. If not 13 volts you haven't connected the little 1 inch braided ground lead running from the starter motor to the starter relay.

Now you have confirmed you have battery voltage at the starter relay. Next:

5. Check the yellow wire to be energized when the key is in the start position.

6. Make sure it is connected to the starter relay. It's a spade connector.

Someone mentioned there are two spades where the yellow wire can be connected to. I don't know the 82 starter but on the 74 there were two posts. One for the yellow wire from the 14 pin connector and one running to the injector circuit for the cold start enrichment. It does not matter to which you hooked it up since the two spades were connected to each other.

If all that checks out you have a bad starter. I think it's unlikely but you never know. Have you had problems with your starter before (intermittant) or can you confirm it worked flawless?

Hm, I don't know if there is a relay under the front hood. But even if so, as long as the yellow wire gets energized while cranking the relay apparently does work. The starter has its own big relay (the smaller round thing bolted to the motor)

All that happens is that the starter relay must have good ground via the chasis and the engine ground strap and battery voltage. The relay get actuated by the yellow wire. That's it.

As I said before I did loosen the second M10 nut when I was on a roll. This is for a little 1 inch braided bare wire that runs between the starter motor and the starter relay. If that wire is missing nothing would happen.

Ingo I am coming to the cunclusion that the problem may be at the starter, the small wire as you suggested or?, the starter and relay are about a year and a half old have worked flawless, im gonna pull the starter tonight and have a look, I have a new relay so im gonna put it on just because i have it, im also gonna test the starter out of the car, Kevin

[thrown_hammer]

Kevin,
I am pullin' for ya man!
(fingers crossed)
