Do these ECU's need to be case grounded?

[phillabaum03]

Just what the topic says. Will these cars start if the ECU is not bolted back up, or does it not matter? etc, my ECU is on the floor, and I have no fuel injector pulse and I've checked just about everything else, and this weird idea came to mind. Its a 95gst. thanks

mine is bolted up buy laying on the floor too. It starts up fine.

 

[phillabaum03]

hmm... anyone else?

Mine spends half it's life lying on the passenger side carpet. No problems.

mine is just thrown back there not bolted up at all, I've started my car and test drove it with the ecu on the drivers carpet with no problems at all. Although I don't really recommend it.

Same in both of my cars and they start and run just fine

damn, well then I hope this crank sensor I just put in will fire her up

 

[phillabaum03]

so I put the crank sensor in, and the car ran. Took it for a victory lap around the neighbor hood, took a right hand turn the the fugger dies like it did the first time. I think I'm wiping these crank sensors out, which could only mean one thing...CRANK FUGGIN WALK

Not likely in a 1990.

Its a 95 gst he is talking about.

Yes, sounds like a case of crankwalk if it trashed the sensor again.

 

[xveganxcowboyx]

Oh shoot, sorry I missed that.

 

[phillabaum03]

fixed it by putting a 1G Cam sensor in, so now it'll either hold itself up or blow. but alteast I dont have to put a new crank sensor in every week . After all I checked and was told, finally found my problem to not getting pulse to two cylinders
