Next, the lights. They do not light up.

My LED ... it is labelled 12 Volt, though the leads are same size. I soldered wires on the leads.




Noid test

So let's summarize your results:

- no ignition pulses to coil. (I would verify the alligator clips wire is OK).
Did you verify with KLR bypass test?
- no pulses at injectors

Based on your results, it appears that the DME is not functioning properly. So back to zero.

​​​​​

Keep fuel pump fuse out till you are able to get inj & in pulses.

In the third video above, I crank while both DME & KLR are jumpered; no fuse; no pulses on LED or Noid that I can see. EDIT: verifyied alligator clips

Will keep fp fuse out thanks

Here's a wiggle wires test


Maybe I should rule out the airbag module as suggested earlier? I don't have alarm.

The DME that was subbed in apparently is a working unit (EDIT: note that I am back using my original DME now)

Verifyed alligator clips on battery; they are good. Reconnected to coil and one more test with KLR bypassed.. this time, closeup of LED.

Look carefully: when I turn the ignition key, you can see the LED flicker

Found airbag module. Before I remove and jumper, can someone verify that all these disconnected plugs are normal?

Airbag harness: Disconnect round connector, its a 7 pin... Jump pins 3 and 4 on the car harness side. Many of those connectors are not used Although the one to the right i believe is the altitude sensor..The CAN looking thing a ma bob.. (Technical term)

I cant help but notice when I hear the video, it sounds like the car wants to start... like it actually sputters... Anyhow.. Just for the hell of it.. Unplug each injector and give it a shot.. I did that once and got a car to fire.. ALL 8 wires on the injectors are parallel ! If one shorts to the other it brings all 4 down.. Just a thought...

Get this thing running this weekend,,, I just got my car out of storage mode.. Dont Make me come up there!

First thing tomorrow, I will work on airbag connector; lunch just ended and we are now gearing up for the long-haul Good Friday annual service. Would look bad if I stayed behind lol

The orange airbag unit looks pretty hard to get at, with no connectors in clear view. Will I be dismounting the orange block first?

Oh, the car wants to start alright... it was running just fine daily until I put it on jack stands in December! I don't think it likes those very much. But.. I can't say I hear anything other than a spinning motor; in fact, I feel like there is something missing while cranking. Mind you, I'm usually *inside* the car when doing that

EDIT: For listening, post #100 has the longest cranking time (wiggle test); I corrected the video (it was the wrong one)

I'll put the pints on ice for ya

Say, what do you mean by this? Crank the motor while all the injectors are unplugged to see if the LED lights at the coil?
