buy a noid light at the local auto parts store to verify injectors are getting the power. If not, Green Wire is in your future.

928 International-Distributor Wire 78-84-green



Write up is in the "Common Fixes" Thread.

Also the Noid Light tester is pretty inexpensive and they come with adapters to fit all size injectors. I think I paid less than $10 for mine at Autozone.

It's been discussed and supplies researched. In the end, just buy the one I posted.

Sometimes, and very rare, someone might have a spare used one that works. At least to get you home.

Signal on green wire tells the control unit the engine is running, this signal triggers the injectors; check the connector at the ecu end of the wire, that is the one farthest from the distributor, by the 14 pin. If you are lucky, its falling apart and you can make a temporary repair there - pull the pins carefully out of what probably is a very brittle connector and insert into the other half. Make sure you match them pin for pin. If the cable is brittle or broken you are s****d, time to but a new one.

..Does it have enough gas in it? (I know this is a different car, but still...) My Mercedes 190e would start and run for a second, and die.. It had just enough gas in it to start for a second.

I decided to check how much gas was in it after I bought a fuel distributor and fuel pumps... Damnit.

How long has it been sitting at this shop? How rotten does the gas smell if you pull the gas cap and take a whiff?

Use the common fixes thread pics as a guide. There will be a piece you'll need to remove on the Disty end of the wire. Take your time on this.

Tells whether your injectors are getting power. No power, injectors wont let fuel through.

They will blink while cranking.

Have you gone through all your grounds? I believe there is a chart in the common fixes thread. Verify all the other injectors with your noid
