95 olds 3.1 sfi looking for all the Grounds

[D Ryan]

I'M looking for all the grounds!

Along the raditor support I think there are 4.

At the back of the engine at the transmition there are 2 studs with alot of grounds.

Battery ground to back of engine.

Thats all I have really found so far! I thought there would be engine to body but did find any.

Can any one help with this?

I don't recall an engine to body. What are you trying to accomplish?

I had to get into the dash to change/swap the ecm , I thought I would find something in that area under the dash but havent seen anything yet. Sence I have gone this far now would be a good time to check and clean . I remember reading somewhere that there were some grounds under the carpet, I checked the pass side but seen none.

The only electrical problem we have had with the car is the rear window defrost dosent work, and now a intermittent in ign system, working on that now.

I had an intermittent no start. Turn key, all lights but nothing turning over. First thought it had to do with the VAT system, ie, resistor in the key not being read properly. Traced it to faulty neutral safety switch under the shifter. Also had to replace battery ground cable, corrosion under the sheathing.

My Ground battery cable needed cleaning also but near as bad as the positive cable, I cut the sheathing off and soaked them in coke for a few hours then shined them up and taped the sheathing back on. Also got some of that dieelectral grease and covered them everywhere, also put some of those felt rings around the terminals. This is what started me looking for all the Grounds. I think the ECM has a ground going to 1 of the studs on the back of the engine, dont know if there are any more!

Are car dont have the VATs system, if someone wanted to steal it they would have to bring a tow truck right now.
What you said about the key being read by the system would be squied or out of sink if the intermittent happened when you first tryed to start,It would probely stay that way until next key cycle, did security light come on or flash?

[aleekat]

no security light. If you key has a small black plastic chip with a wire at the surface on both sides. That is a resistor, not a true "computer Chip". You can read the resistance with an Ohm meter. Found a guy on ebay who sells blanks pretty reasonable. You just measure your resistance and tell him what your reading was. If memory serves, think there are like 14 different keys. This doesn't need to "reset", it just completes the circuit.

Again does anyone know if a engine to body ground exist on a 95 cirrra 3.1 SFI?
