Please help! Parasitic Draw in FP/ASD (21) - SRT Forums

USMCgamer · 10-13-2009, 01:45 PM

So my car has been dieing if i don't start it at least once a day. I used a test light on the negative terminal while removing fuses to see where the draw is coming from. When i remove number 21 (FP/ASD) the draw disappears. The fuse isn't blowing its just drawing power when the car is off. Any ideas whats causing it? I have a walbro 255 fuel pump, stock ignition coil, stage 1 pcm and i am having the tps wire problem.

Some current draw is normal if its small.

How much are we talking about?

enough to kill my battery if i dont start the car for more than a day.

A crap battery will do that too, with little to no draw

,,,thats why I asked how much?
How many milliamps?

The only thing in that circuit is the fuel pump, injectors, coil and noise suppressor.

I don't know i used a test light but ill put a meter on it tomorrow and let you know. Thanks for the help guys.
Also, why would any of those components be drawing any current with the car off anyway?

Ive heard if oil gets on the noise suppressor it might shit the bed. Check the basics and recheck them. report back with findings of power draw.
