I have a 1989 Accord who's no. 1 injector seems to have a connection problem. I can apply pressure to electrical connection and it'll work. Anyone know a cheap fix?

 

Replace the wiring harness and/or the injector (depending upon which is damaged).

 

I've moved this to General Tech - please do not post questions like this in the DIY Section - there is a sticky in there about this.

Is the metal "clip" on the connector? This clip "locks" the connector on the injector.

 

Yes, the clip is intact. I've looked at the terminals and slightly tightened them. It works for awhile.

 

Sounds like time for a trip to a bone yard or buy a new one - some parts stores offer these connectors.
