Fuel Injection Bible

[ramsesosirus]

Ok, so I'm reading the EFI bible (single best car information I've ever read...) and want to test components via the ECU 35 prong connector.

I don't want to damage anything.

Before testing with voltmeter/ohmeter do I need to

disconnect battery or not?

anything else?

It says disconnect ignition before disconnecting ECU connector, does this mean disconnect the coil wire or what?

Thanks

Actually, it says "Turn off ignition before disconnecting control unit". Just that. You don't need to disconnect the battery. You'll need the power for the tests. Make sure you follow the notes at the bottom of each page in the tests. Another note: those tests are bacally for a 75 which doesn't use about 8 of the pins and IIRC a 76 uses all 35 pins so I'm not really sure how accurate those tests will be for you.

Thanks sblake, you always seem to know! That kind of sucks, about the 8 extra pins, I thought I was bout to figure out this rich problem....; Just double checking about ignition, don't want to create any more problems!

I'm starting to wonder if I have enough time to figure this out before winter, then it will be too cold to do much!
