P1800 ES

As mentioned before, 1 of my parts customers in NH recently couldn't get the engine we rebuilt for him to start and his mechanics made a thorough examination and couldn't find the cause even after they tried a good used ECU I sent to them and checked all of the electrical connections.

It turned out to be the pressure sensor was damaged in a way that it wasn't capable of sending the required signal that the ECU needs to properly fire the injectors even though held vacuum and was in spec on the resistance tests. The importance of vacuum pressure sensor is is mentioned in the article from Dr D-jet that I posted a link to(Did you read it?).

When the mechanic installed a good used pressure sensor, the car fired right up even though it was the wrong pressure sensor.

Do you have a spare vacuum pressure sensor?
