Running Rough "fault codes

[ajhenry]

Okay guys I ran the codes on my car and got codes 217, 542 and 566
1. code 217 states coil slot 3 on the ignition coil pack is bad. I replace the coil pack but same code
2. code 542 states fuel pump secondary failure
3. code 556 states fuel pump primary circuit failure

I had a new 190lph pump put on 2 weeks ago by ford
Should I try replacing the plug to the coil pack

Thanks

Check the output connector from the DIS module and the connector into the coil pack. The code refers to the coil #3 circuit and could be a wiring or connector problem or even internal to the DIS module. The coil pack would have been the first thing to check though. Sorry that didn't work.

Do you know if ford sells the DIS to Coil pack connector
I am thinking of just replacing it

I believe that wire routing is part of the much larger engine wiring harness that runs around the firewall side of the engine.

Okay if the wireing is bad or the plug can I splice the plug wire and replace it with a new one or what do you recommend

I'd have to look at a wiring schematic daigram for the wire routing and coloration, but I'd check each of the conductors for continuity between the DIS module output and the coil pack. If you find a bad wire, route a new one. If none are found to be bad, check the connectors and tabs for breakage or corrosion.
