See part numbers at the top of the listing and check this against your original. This unit offers a 30 day functionality warranty.  These very commonly have issues with failed capacitors, I always check for this.  This one is good- Most likely these defective originals have been replaced at some point.

 A faulty ECU is one of the most common no start or random stalling problems with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate.If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the trunk. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older.

Please note, that misdiagnosis of a good working ECU is one of the primary reasons we get these units returned. We no longer accept returns on these units without a 30% restocking fee and there are NO refunds on our original shipping cost. We test all units we possibly can, and will test any returned units. All units we sell are operational units that came out of crash damaged salvage cars. Unlike most sellers on ebay, we never sell ECU's from no-start cars or from flood damaged cars!   Please see our website epartsland.com if you are looking for an ECU you can't find on ebay.
