my 00 hatch with y7/y8 mini-me was working fine. Now it wont start. No cel's. The fuel pump wont come on, no spark, injectors are dead. I checked all fuses, replaced the main relay tried 3 different computers . I was able to get it running once by jumping the fuel pump. Which the fuel pump will work when I do this. But the car now doesnt run.

I also ohm and voltage checked the wires going to the main relay and checked the main relay.

Clean and tighten the G101 ground wire attached to the thermostat housing.

I gave that a try no go

Former User

Do these electrical tests with a digital multimeter when the fuel pump won't prime:

Whats odd is the injectors arn't firing and there is no spark also

Former User

You did ALL the tests in the diagrams and then swapped in a known good ECU?

What were the voltage and Ohm readings?

Yeh I did. Around 11.5-12.2 volts. and .2 -.5 ohms. Im at a loss

Is it possible that the whole under dash fuse panel took a crap?

Former User

In the very last step, was the voltage reading between A16 and B2 1.0V or less? What was the reading?

.01

ok i re-did the test .20-.35 volts

Former User

Test the main relay.

I did. Both the old and new checked good

Former User

When you turn the key to ON(II), does the CEL remain on steady both with and without the service connector jumped?

Eaglekper0046

Yes

Former User

Do these additional tests:

Ok Ill give it a shot. Thanks for you help

Everything checked good. Im a bit un sure about the step that says to check for 5 volts. Both reading I got 4.97 which is close enough I guess.

Former User

There are two tests that can yield 5V. Which one?

Former User

This says that you had spark but no fuel at one time. Have you recently checked for spark? If so, how? Are you now unable to start the engine with starter fluid?

Former User

I suspect that some tests were not done or interpreted correctly, so you need to give details about how you are doing the tests and what readings you are getting.

First verify that the engine won't start. Then repeat all tests. Post the readings at each step and, where there are branch points, indicate which branch was taken.

I did yesterday But ill check for spark again. Havent tried with starter fluid ill do that to.

No spark
