Eta-to-M50: Build thread

[samiam3356]

immpossible to have the crank and cam swithced. One is male and the other is female. You could have them plugged into one another but not wrong on the harness side.

good luck man...This is the frustrating part but also very rewarding when you figure it out. BTW did you use new sensors?

[Jand3rson]

Gotcha, we'll bust the multimeter out and start checking everywhere we can as soon as I get access to one.

Nothing else I can really check until then.

No you aren't getting fuel. Do the injectors squirt with the pump jumped? If you aren't getting spark, then the fuel injectors aren't firing more than likely. Your method of testing for spark is a little iffy but I'm going to say your ECU isn't getting a signal for something.

Humor me and swap those coolant temp sensors. You never know...

Next step would be checking for proper resistance from your CPS. The car will start without a CAS but def won't start without the CPS. Your engine grounding is fine, otherwise the car wouldn't crank over that strongly. Do you have another ECU you can try out? You'll need to really start breaking out that multimeter.

CPS and cam position sensor interchanged?

No, I have checked that several times now.

Crank Position Sensor? Have you checked the resistance on it?

I haven't, I don't have a multimeter, I'll have to wait until later to check that stuff, Andrew does, but he works until this afternoon.

We are definitely getting fuel with the jumped relay, but the the actual relay in, the pumps don't come on. So we're getting fuel, but no spark?

You are grounding the plug on bare metal, right?

I laid my plugs on painted VC, and got spark

It could mean many things. your FP relay is more than likely ok. I'm going to guess that your DME is not getting a crank angle signal. Perhaps you swapped the cam sensor plug and crank sensor plug? I think another time this happened the coolant sensor plugs were reversed. Please verify you aren't getting spark.

No change swapping the cam and crank sensor plugs, and the coolant plugs should be right, I put the blue one to the blue sensor, and the other one is right.

I don't appear to be getting spark, pulled a coil pack/plug and held it to the valve cover, no sparks, and after swapping cam/crank sensor plugs, now I've lost track of which plug is which under there. Awesome.

damn!! im goin crosseyed! just spent half hour reading thread. nice build. still havent seen it all. wish i caught it sooner.. well done sir

[Jand3rson]

Time to get out a tester and start checking at the DME?

Don't have one, I'll have to wait for Andrew to get off work.
