No Throttle Response

[dartman48]

Hi guys, I just finished installing my EGT and Boost gauges. Actually, the EGT is not yet connected to the probe. I started the truck to check function of the boost, and I have no throttle response. It starts and idles fine, but no change when I push on the loud peddle.
What'd I do?

I've checked further, and I have no instrument function either. I went through all the fuses and relays, to no avail.
When I turn the ignition on, none of the gauges stay flat, no response. I must have bumped a connector somewhere. Will that throw a code?

Hey welcome Dartman!
This is more of a bump for the Techs and smart guys on here but how did you install your boost gauge?

you will probably have a fuse blown, and it will be a 20a one if i remeber right that is in the inside fuse block. You have a wire for the overdrive button that comes out of the shifter lever under the steering column trim, that wire will be frayed if you remove the trim and inspect it. The easiest fix unless its barely worn through is to replace the shift lever. You can use tape for a temp fix or even a permanent fix if its barely worn through

I checked the fuses, at least the ones I felt would pertain to the engine and instrument cluster. I guess I'd better check them all.
As for the Boost, I put a tee in the MAP hose and ran the tubing to the tee. Isspro uses this method, I just boorowed it for my AutoMeters.

I got it solved. As I guessed, and you confirmed, it was a fuse (that's all it could have been). It was #45 - Ignition Switch Run/Start feed.
So, all's well. It's nice to know there is a lifeline out there for us "shade tree mechanics" that get in trouble from time to time.
I've got an interesting twist on gauge pods. I'll post it in the 7.3 Mods section.

that fuse will blow again. You need to pull the steering column trim and deal with that wire the insilation came off of i told you about though.....
