THe ECU nightmare continues......HELP!!!!!!!!!!!!!1

[AudiCoupeParts]

Well, I picked up another "claimed to be good" 3B ECU that is stock with zero mods.

I found that my ground strap to the block was not correct and I fixed it. Engine cranks great and I have good spark!!! I shot some engine starter fluid into the manifold and the car fired right up!!!

THe injectors are not activating, I get power to them 11.4 volts, but no ignition from petrol. I don't here them click or do anything.

Fuel pump relay clicks on during cranking and the pump comes on but the fuel pump sounds very weak.


Checked codes on ECU and I get the same codes 2111, 2121, and the 1111


All fuses are good.

I checked all the ground straps. Manifold, battery, block, and foot welll area. All good.

For the life of me I can't figure WTF is going on!!!

Any ideas?????


Thanks

It seems I'm not the only one with bad luck... You've mentioned fuses. There is some naughty and tiny boxes called thermo fuses. S72 - 12A. Have you checked them?

Looks like fuse, but has aluminium case.

ECU is not doing code 1111!!! IT was doing 0000!!!!

It appears that my Ford Racing Green-top injectors are NOT working. Power and signal are going to them but they are not opening.

Has anyone used these Ford injectors. They only read 14.7 Ohms and Bentley says they need to be 15 to 17 ohms. Could that be the problem?

You've needed to mention, that you made some changes to the hardware . Good, that you have found cause of the problem. Maybe you should pull them out, and go with them to the flowbench (some place where people fix injectors) and check what they are capable of.

Also same ppl usually have means to meassure fuel pump pressure and flow.

Also it's very interesting about all your upgrade. Have you told MRC, that you are going to use different injectors, when you have ordered remap?

Because, if not, I suspect, that remap (chips) may not work properly.
