Art & other responders,
Purchased a new CPS from NAPA. I tested the old one and the new one with an Ohm meter and I have found/determined them to be identical.
Yes, I didn't plug the new one in as NAPA would not take it back once plugged into the system so I opted to check it with an Ohm meter instead.
I got the same results on both. I re-installed the old one after cleaning off all the oil with Gunk engine brite before I re-inserted it. Still no change.
Here is what I know and what I've done so far:
1. Car cranks, no ignition.
2. I've checked the fuel pumps and they both pump. I hear the whirring sound when I let off the key.
3. I HAVE spark at all 4 spark plugs.
4. Checked all 4 injectors and I am reading 16.8 Ohms on each one, so according to Chilton that should be fine.
5. Moved intake manifold grounds to the fuel rail as outlined in Chilton & Haynes manuals.
6. Cleaned up ground from firewall to passenger side of the valve cover.
What I plan to do tomorrow:
1. Attack the ECU (I suppose this is the Jettronic marked box on the right passenger side of the car.
2. check coolant temperature sensor
3. cold start injector
4. Check throttle switch
5. check air mass meter, and the
6. air control valve
7. fuel line pressure regulator
Have I missed anything????
Just rambling here but I know I have gas flowing (A question about gas flowing is ) and spark, but is it really getting through the fuel injectors? This is what I don't know and I don't know how to test this. What should I be looking for at the injector connectors?
Please advise.
