Yep, I still think its the ecu if there is no CEL.
Agreed. If the CEL light is in place and has been tested for continuity (they take way more than 12 volts to 'blow' trust me) and the socket has been tested for voltage so you knowe that this circuit has not been cut before the dash, if you get no CEL light at startup then the ECM has probably got bad capacitors.
At this point you have nothing to lose by replacing the capacitors do you? Can't do it get a buddy who can solder, but with a little bit of practice you can do this job.
Soldering is easy. All you have to do is count seconds in your head when soldering something. Say two 14AWG wires that have been twisted together.. Get the soldering iron hot, clean the tip with a damp sponge, tin it with some solder...not too much. Make contact with wires, now once you see some movement (3 seconds at the most) add some solder..not too much get off of wire after two seconds. Admire your beautiful soldering job! You should see the outline of the twisted wires like they were two lovers under a wet sheet!
To de-solder joint using an ear bulb syringe. Compress the syringe before you melt the joint. Once the joint solder is liquid suck out the excess solder with the compressed syringe by letting the air out of it.
Another method for de-soldering joints is with some small metal braided material. Again you get the solder liquid and lay down the braided material. It will wick up excess solder.
There are several very good posts here in JF concerning this whole capacitor replacement process.
Again I ask you if the ECM is NG what have you got to lose by 'operating' on yours?
