Clean, tight connections at the three-prong ground are very important for proper FI operation. I would also recommend cleaning two other grounding points. One is the transmission-to-body ground. Clean the connection on the top of the transmission, the connection on the bottom of the rear trunk and both ends of the ground strap that connects these two points. The other is the grounding point beneath the relay board in the engine compartment behind the driver's seat. There is a cable-to-body ground point there. Transmission to body is good - that I'm sure of. I'm not sure of the other ground point you mention - will check it out tomorrow. What connects there? What cable are you talking about? |

You also have to have the injectors/cold start valve connected and the TPS while you are at it. Have you heard the injectors click? If they were rebuilt or have been sitting awhile they may be locked up...you can free them by tapping them with a 9V battery. The better test is to verify your fuel pressure with a gauge, then shoot each injector into a jar to check for flow and pattern while cranking. Hey Jeff, I assume you mean a small 9V transistor battery. Well I just tapped all of the injectors and all I got was a spark at the battery. If I was supposed to hear the injector click, I did not. |

Remove the plug from the injector.
Use a AA battery with two small alligator clip leads to plug into the injector. They should click, loud enough to hear. If not, pull them out, soak them in Tektron FI cleaner for the night, fully submersed. Pull them out, dry them off and try again. Rich |
