Do you have an LED light that they sell at such places as Radio Shack for $2?

gotian

iTrader: (1)

no, because its very hard for me to get around since this is my only car and the only radioshack is a good 15 miles away

gotian

You still havent ruled out the AFM meter yet.... you could have a problem in the wiring harness. You've got the multi meter and that is a good thing at least. Backprobe pin 2E at the ECU and see if you get any voltage there. With the key to ON you should see around 4 volts.

can you link a diagram of the pins so I know which one 2E is?

I guess the good news is that we are running out of things that arent wrong with the car right?

gotian

i cant find a diagram of the pins, cold someone help me or tell me what page in the manual it is?

thanks im going to check it out, just to make sure i do it using OHMs right?

satch

Volts!

gotian

iTrader: (1)

okay looking at the diagram doesnt help too much, which pin is the 2E?

gotian

iTrader: (1)

volts it is, lol!

satch

2E = middle plug, top row, third from the right, which is Green/Blue, just to the left of Mr. Blackwire.

You'll also want to get a reading from other pins as well.

Pin 2A Brown/White = 5 volts w/key to on
Pin 2J Green/Orange = 2 to 3 volts when air temp is 68 degrees w/key to on.

so i dont unplug the ecu? damn let me plug it back in, i'm just getting really tired, lol.

satch

iTrader: (1)

Plugged in.

gotian

iTrader: (1)

third from the right is a blue orange wire for me

satch

iTrader: (1)

That's third from the left!!!!!!!!!!!!!!!!!!!!!!!!!!

gotian

iTrader: (1)

2E with key turned on reads 1.8 is that bad? sorry satch about the confusion, im just really tired at this point.

satch

iTrader: (1)

Well it's not good as it should read 4 volts. So you measured the Green/Blue wire located just to the left of the Black wire?

gotian

iTrader: (1)

yeah i did, let me make sure i did it right, i put the red probe in and ground the black one right?

also 2A is reading 2.5

gotian

the FSM says after warm up but as you know that is impossible for me at this point

You're getting values which are half of what they should be. Is your battery about dead? How about charging the battery overnight and trying to get some better reeadings tomorrow. Pin 3J is the smallest plug and the wire is White/Blue located bottom row far left corner. This gives the reading of the battery and it should read 12 volts w/key to on.

Also use either of the two mounting bolts of the ECU as your ground. There is one in the front right of the ECU and the front left as well.

Not needed for the pins you are measuring. If it were the TPS pin then that would be different. There is another member on another thread getting the proper readings from the same pins as you are and he is doing so with the key to on as his car cannot start either.

battery pin is reading 1.9

I'm going to take the battery to work tomorrow to charge it.
