Speaking of battery. What is voltage with key off, position 2, position 3?
That's odd, because I could hear it running after the probably 5th starting attempt.SAI pump should not run until engine starts and runs for few seconds.
I'm not sure what the voltage is and I have no way of really checking, I am going to connect the battery to a battery charger and see if that has any effect at all.Speaking of battery. What is voltage with key off, position 2, position 3?
You are correct but my thought was the first thing that happens when key goes to position 1or is it 2 is the pump primes. Just was wondering if that was happening.Hold it gents. I thought we are looking at "no starter action" condition.
Get a cheap meter even one from harbor freight.That's odd, because I could hear it running after the probably 5th starting attempt.

Not yet, going to clear all codes and then install sensor when I get home tonight and see how it runs.That’s great to hear!
Witek would know more but engine temp is usually taken into account as part of air fuel mixture. So could be the sensor, I start there and double check all injectors are plugged in properly.
Have you read for any codes.
Browse trough this. All pluming around intake manifold, egr and air injection.Put the new sensor in, helps some but I do have a vacuum leak. Not only is it still running awful, I can hear hissing sounds, and when pumping the brakes while the engine was running it actually caused it to stall. I know the vacuum hose on the front of the engine that splits into the two diaphragms and into a sensor needs to be replaced, and also the plug for a vacuum port on the back of the intake, nothing connects to this one. But I don’t know where to source these lines, any suggestions?
I did find the vacuum line itself, however I'm still having trouble finding the cap for the back of the intake manifold. That's the main source of my vacuum leak right now, used some duct tape as a very temporary solution to the other vacuum line being broken.Browse trough this.

I could not find a part number or the part itself. The old one disintegrated when I went to take it off.In the diagram that Witek posted which diagram and what is the part number for the plug.
Most vacuum plugs are generic as well. What happens when you close the port with your finger. For interm you can plug most ports with a short lenght of hose and a small round head machine screw that fits tight in the hose.
I have like 4 99 and one 98 five and ten minutes from my house if it is a special molded plug.
What happened to the plug from your old manifold?
I take back you did say cap not plug still need part info
