Thanks for sharing👍 What an awesome tip to start with, this simple test can save hours of testing😉

The ideal way is to use a scope, but too time consuming.

Hello, I had some body work done on my car and believe I lost ECU ground. Car will crank but no start, no fuel. Multiple Scanners will not link to OBD2 even though I have 12 volts on pin 16. On pins 6 and 14 of OBD2 connector I should read about 60 ohms for CAN high and Low signals but I read read about 180K ohms with battery disconnected. Do you think I lost my grounds? I need to do some more testing but could it be as simple as running new grounds to ECU? I'm a bit of a novice so sorry for the dumb question.

Its not a dumb question. I have the same issue on my 96 corolla. Crank/no start, no spark, no fuel, battery at 12v, all fuses checked, relays click, new crankshaft sensor, new distributor assembly, new fuel pump assembly, new plugs/wires...and every circuit reads in range on my multimeter and testing light. Yet.... after ALL this, and that....crank/no start. So, Id like to know too....could it be my ECM/U?? To be discovered.......

My tps ground terminal 1 harness connector to tps has .4 ohm key off but 5.4 ohm key on ??? Any thoughts Ground to ecm is .3

Don't use Ohms to test leads. Use voltage and please stress the output. www.autodiagnosticsandpublishing.com/Stress_Loaded_Tester.html

Nice video 👍 sir

Thanks for watching

Thanx Bro

[@ADPTraining]

Cool

[@Eurospec73]

I think I might have fried out my ECU because the ground wasn't connected to the transmission. Oh well🧐 I guess there's a first time for everything!

Bummer

@@ADPTraining It's a very easy thing to do, unfortunately many others have made the same mistake I have, it's the first time it ever happened to me. I don't know if you've ever experienced something like this, but it's the last thing I ever want to see happen. It's quite frustrating!
