Niceville,
Florida
Car is a 96 Eagle Talon AWD TSI mods in profile, battery is Optima Redtop and was/is fully charged.
Ok, Longstory short, I was pulling out of my neighborhood one night and car was running great, however a mile or so down the road the car seemed to lose power off and on (lights/instruments stayed on the whole time) for about 5 seconds or so, then then car just shut off. After that the car wouldnt start, but it would crank just fine.
I popped the hood and it seemed like the battery tie down came loose and the positive terminal shorted out on strut tower brace. I retightened everything and tried starting the car and it still wouldnt run. I then noticed the fuel pump wasnt running so i hooked up DSM-Link to my laptop and tried to turn the fuel pump manually, i could hear the relay click but i could not hear the pump running. I got the car towed to my house.
Took forever to find the fuelpump and mfi relays but i finally found them and tested them both at ~73 ohms, which is close enough to the 70 ohm rating. I then connected a voltmeter to the plugs going to the relays (as a member suggested On post 17 of http://www.dsmtuners.com/forums/newbie-forum/276071-mfi-fuel-pump-relay.html ) The first relay plug tested at 12.0v exactly and the second plug only tested at around 7v I had the key on the ON position but did not try cranking it. Ill post pics later today about which relay i tested at 12v because im not sure which one is which (the first relay is on the bottom when the relays and plugs are bolted into their bracket, and tested at 12v)
The first relay clicks a few seconds after i turn the key to the off positition but the second relay that read ~7v doesnt click at all. I tried using a wire to jump the 2nd relay but my pump wouldnt turn on either.
Also the car sounds really weak when i try to crank the car (battery is fully charged) and im afraid when the battery shorted i melted some wires leading to the starter and the relay.
Where can i find the wires from the relay to the battery? and how would i go about testing them? What would be the first fix/test that you guys would try?
Sorry for all the questions but it seems that all the solutions that many members suggest are very vague about where to connect power sources to what etc. Pictures and/or detailed solutions would be GREATLY appreciated. Thanks
