Well, I just got my first Z. It is a 76 280Z with 185,000 miles and looks like it has been partially restored. I've been driving it around town and noticed a substantial loss in power after taking it to the gas station for the second time. Going from 0-30mph took over 10 seconds and going up hills was painful. I took some advice and replaced the fuel filter and gave it some fuel injection cleaner, but the problem persisted throughout the day.
I downloaded the EFI bible last night along with the factory manuals and planned out some tests for the car. This morning when I checked the continuity between each of the fuel injector contacts and they all checked out. I looked at the plugs and found they were all pretty fouled and somewhat wet.
Then, I noticed that the car wouldn't start. The engine will turnover, but won't run.
I replaced the spark plugs, but it didn't help.
I can hear the fuel pump (its loud)
I tested the plugs outside the engine and I'm getting a spark.
I started testing the ECU as outlined in the EFI bible and found a couple interesting things.
I'm not getting continuity from the airflow meter, water temp sensor, or air regulator
Pin 1 is getting 12v
I'm getting varying voltages to my injectors (between 0 - 11.6v)
I know that is a lot of information, but I'm stumped and I want to be as thorough as possible.
So, could my sudden loss in power have contributed to the engine not starting? What should I look at next?
Thanks!
