Hey guys, i got a problem. I was driving down the interstate this morning and all of a sudden, my car dies. Won't fire up. Anyway, I got it to the house and found that the E.G.I. Comp fusible link under the hood is blown. So, i got get another thinking that is the problem. Well, put it in and try to crank. Still want start. I go check the fusible link, and it's blown again. What could the problem be? Please help!!!! By the way, it's an 88 n/a. I checked for burnt or bare wires around the engine, but couldn't find anything. Could it be a wire under the UIM?

 

What kind of mods do u have on your car?

 

The 30a EGI fuse feeds all those solenoids on the solenoid rack plus the two solenoids on the ACV. So first look to see if you see a bare wire near the acv, and the solenoids......then pull all the plugs off the solenoids and install a new fuse. If it does not blow...then reattach each one until the fuse blows.

A number of these fuses blown are attributed to the solenoids on the acv. Not the solenoids themselves but the wiring AT the solenoids.

It also feeds the air bypass relay and the boost/pressure sensor...on a series four.

 

we used a multimeter to track it. The short is coming from the acv itself instead of a wire or a solenoid. Why would it be shorting out? Any ideas?

 

Use a test lamp, place one lead at the positive terminal on the battery and touch the other to the downstream side of the fuse terminal. Notice the brightness. Now do the same on another good circuit. Notice the difference in brightness. You want to wiggle the electrical cables related to the EGI comp circuit until the brightness dims to the like of the good circuit.

First, before you touch anything, look at the wire clip holding the wire bundle right at the pivot bolt for the altenator. Is it a metal clip or does it have a rubber surrounding? If metal, check if the insulation has rubbed away. You don't have to actually see wire to have a short.

This is where my short that did the same thing to my car. Wrapped it with electrical tape, removed the metal clip, and put in a new fuse. Haven't had a problem the last 60K. Good luck!

 

There are two solenoids on the acv. The front one is the Port Air solenoid. It is never opened after the car reaches twenty thousand miles. If this is the one that is shorting......disconnect the electrical connector and go about your business.

If it's the rear solenoid.....swap the two solenoids and follow the instructions given in the paragraph above.
