wheres the first place i should be lookin for to find the short. it just happen the other day out of nowhere..now the car wont start..i have no fuel and no stark. any help is good help.

Just a WAG, but based on what you said, maybe you should check all your ECU wiring for a possible short or to see if one of them is not grounded. Check to see if the ECU is properly grounded and check all wiring leading away form the ECU.

just check if u dont have splice wire some where . i alredy have this trouble wiht a b20 in a 4 d00r it was splice wire to the injector

this has to have happened to someone else.......

If your ECU fuse keeps blowing then I dont think there is a way to tell EXACTLY where your problem is. You have to check all the wiring leading away from ECU and see if one of them is shorted or grounding out on something in the engine bay.

EDIT: First check the ECU iteslef where the harness plugs into then look in the engine bay. And when I say all the wiring leading away from the ECU I mean check the wire es from the ECU to whatever it hooks up to in the engine bay.

Like in the problem that slowpos was talking about, it sounded like the wiring problem was a frayed wire for one of the injectors. If the wiring anywhere between the injector and ECU was frayed then it may be grounding/shorting out on some metal nearby.

thanx alot....
the car now starts and keeps fuse for a minute then continues to blow there after. weird problem. ive changed ecu's and checked all wires. the only thing wrong right now is that i have a leak in my fuel filter but i dont think that would cause it. any other ideas?

slowpos

do you know if your other ecu is good check inside if u didint see something ... and if the car have the same proble with the knew ecu check this one to ... if both have something wrong you have wiring problem i alredy have this trouble with a swap b18c in a eg

this has happened to me before...definately a short somewhere...what's the last thing that you did to your car...go back and check that...clue is something has to do with your ecu...not stereo...or headlight...mine was an easy hunt down...but your problem..good luck...

see if your o2 sensors wires are grounding out near your exhuast.

Definently check out the O2 sensor wires. I had the exact same problem just as I finished my swap. Turns out that it was a thin *** piece of wire stickin out of where I extended the o2 wires. It was grounding off tha exhaust, what pain in tha *** to find

Your engine grounds may not be getting the best contact ..
