Major Electrical Issue

[tagyoreit]

Please help me out boys. Quick summary. 2002 GTS - Electrical mods include: Underglow/Interior Strobes/Interior Neons/Grounding Kit/Shift Light/Audio system and Fuel cutoff spliced between the fuel pump power line. Issue: I've blown the fuel injection fuze 4 times now and it's very random. Car just stalls and dies without warning. When this happens I have had different combinations of electrical componenents running so it's extremely hard to pinpoint. What would you guys suggest me to do? If i had to guess i would say it had something to do with the fuel cutoff switch and maybe I should bypass it for a while... any ideas please help! Shall I start disconnecting electrical items off 1 by 1?

I suggest unplugging ALL the new electrical components that you installed. The fuel cut-off switch would be my first concern. Get rid of it until you fix the problem. Your added electrical components should be on a fresh power wire directly connected and fused at the battery. If you need to, run a relay directly off the battery and use the ignition as the trigger to turn them on. DON'T pull power from the fuse block. You have a lot of stuff running. Start there. Drive the car for a week or more with none of your added things and see if it does it. If not, then you can re-wire the added stuff to the battery, and not the fuse block.

That's just my suggestion.

Curt my friend, we meet again... thanks for the input. That's what I was thinking. Right now, everything is wired direct to battery with inline fuses so that's a good thing... I think it's this fishy switch myself. They seem to go bad real fast. I'll give it a shot. Do you know what else can possibly effect the fuel injection system besides the pump wires? Can the battery have anything to do with that, or any other wiring in the car for that matter? It just leads me to believe that is has to be that damn switch.

Yeah, the switch would be first on my list. Sometimes if the contacts on the switch are not solid, it causes arcing, and that will blow the fuse. Since the rest is already hooked-up to the battery directly (with fuses), then the switch seems like the only possible problem. If you take the switch out and it's still doing it, then there is something else wrong.
