Blowing INJ-1 Fuse

[Blue Flame Restorations]

Trying to troubleshoot the 88. INJ-1 Fuse is 7.5 amps. Upon acceleration of RPM's the fuse will blow. SES light on.
Getting ready to count flashes.

Any input would be appreciated.

Thanks

Brett, you didn't have the plenum off for any reason lately, didja? I pinched a wire once and had the same problem (fuse).

Might wanna "ohm" out the injector harness...methinks.

Had it off many times last week.

Thanks, Paul. I'll check it out.

Tyler and I figured it out. Problem solved. The INJ-1 circuit had too much draw.

Why?

We had piggy-backed that circuit while getting a constant 12 volts to the fuel pump.

Without getting too deep into it, I'm using the original harneses in the car. Every harness has damage that is being repaired.

The good news is, the car starts, holds good oil pressure and the charging system is functioning well. All gages work as well.
