I'm trying to get some oil in my car since I just installed an oil cooler. I was told to pull the ecu fuse, which I believe is #31 under the dash. I pulled it but my car started anyways.

Should I be pulling #47 instead ( under hood ) or should i just disconnect the ecu?

 

disconnect your fuel pump harness and unplug your spark plug wires from the spark plugs.

Would I be able to just disconnect the ecu instead?

BTW, i tried fuse #47 and that didn't work either.

 

disconnect ur fuel pump fuse and u should be good

 

you must not be pulling the right ECU if you pulled the ECU fuse..it will not start. it will just crank

 

Or you can just unplug the ECU.

that or you can just take out hte fuse for ECU that is right next to the battery under the hood.

I would not remove the plug wires

The two fuses for the ECU are 47 and 31. I pulled each one, but not together, and the car still started.

If I just pulled the ecu, would that flood the chamber with gas?

There's one under the hood called "backup fuse" - I forgot what number it is, that's the ECU fuse, pull that.

Screw it, i just pulled the ecu itself. It cranks w/o turning on now. Thx guys. Again, anyone know if that's bad for the car? should I be pulling the fuel pump plug too?

 

it's #47, i already did and it still let the car start.

What's he supposed to do, plug the ECU back in while he's cranking it over?

How is that possible, at some point or another he does have plans of trying to start it.

At OP:
It's fine for the car, with the ECU out it shouldn't pump fuel either, so you shouldn't get a big rich blast on the combustion stroke of the first cycle the first time you try to start it again . Good luck with your new oil cooler.

 

If you unplug the plug wires and the ECU's still trying to make it spark, you'll kill the dizzy. Don't unplug the wires.

If I wanted quick and dirty, crank and no spark, I'd just unplug the harness connector from the dizzy. You can also simply apply 12 volts to the solenoid plug with the key off and it'll crank but, not spark OR run the fuel pump. If it's in gear, it'll run you over so be careful.

Thx. I'm going to have to try to pull the ecu fuses ( both #47 and #31 at the same time ) to see if that works but unplugging the ecu definitely works. It sucks that the oil cooler lines had a couple of leaks though.
