Well, the fuel injectors are spliced into the harness; these commonly fail on the older trucks. We recommend removing the butt connectors and soldering them for a repair.

If you want to say to heck with it; pull the fuel injectors and send them off to be refurbished. www.rceng.com or www.witchhunter.com About $25 each plus shipping. Send the CS injector too.

About the only way to see the spray pattern is to pull it and ops check it per the FSM.

Tip: O-rings are wetted with FUEL, not anything else- for reinstalling.

Hope that gets you further along.

Might be a long shot too, but there's a TSB for the 22RE for hard start/rough idle. Go to our FSM sticky here, then go to the online library link, and log in to find it. Can't post a direct linky to it here. <img src="/forums/images/graemlins/kewl.gif" alt="" />
