Towing my car to Electrical shop tommorow

[Alex_95TSI]

$50 for towing 2 miles away from my house
+
$90/hr for auto electronics shop to look at my car estimating most jobs require less than an hour.

= 1 said DSM'er

ECU not getting any power, all fuses/relays in working, MFI relay replaced but detected somethin weird going to the relay wires, cant hear feul pump priming, no spark, no lights on dash coming from ECU, headlights, ajar, turbo timer all getting power...etc. Im hoping my ECU is still good (eprom) b/c i opened it up and everything looked to be in good condition...

1. Every DSMer should have AAA or a tow truck or a friend with a tow truck.

2. Why not just pull the ECU and bring it to him.

You know what, thats pretty funny because i was actually thinking of that today myself (about AAA).

I'm not convinced its my ECU. Could be something other than that.

I got money on a bad ECU. Swap it before you send it anywhere. Come on, dsmers don't take their cars to shops.

i COULD swap it with my friends car BUTTT no way in hell do i want to mess up his ECU as well. I need to find the problem that potentially blew my ECU before i even think about swapping them.

I couldnt find that problem, and i am a novice when it comes to automotive electrical trouble shooting. I had to give up on this one.. I dont know of anybody that could have helped me with this problem... Hopefully they will find the problem in under 2 hrs which would be $190

MFI relay replaced but detected somethin weird going to the relay wires, ...

Well what? Did you check the 20 amp MFI system fusable link? The circuit is pretty simple. It goes from the battery thru the fusable link, to the MFI relay, to the ECU.

 

[Alex_95TSI]

Yeah i know it is simple.

It ended up being a hidden aftermarket relay that previous owner (ive had this car for 1.5 weeks) wired up. It was preventing the ECU from getting power....


$230 for that mistake. goddamnit
