Interpreting results from a scan tool are not always straightforward. What did it say? Did you have a mechanic diagnose it? And you'll find much cheaper parts from a parts store than the dealer.

Yes, he said computer failier. Said also that he put his ear near computer and it was sizzling sounding like something sparking inside.

Ouch. OK. Still, it's not necessary to buy it from the dealership. Call around local auto parts stores, and if you do the installation yourself, take all anti-static precautions.

hey i know im asking loads of questions(sorry). I trust my mechanic and all... I really dont want to buy a new computer and for the problem to persist. (I am looking to purchase one by the way). I been doing alot of research online. Anything about a fuel pressure regulator could cause car to stop and all ignition light to go off? Sigh.

Also, i took the number on my current computer. its P/N/P05293013AC-0529
S/N/T08EH063771845-15.42.27

See i want to get the right ecu. Do i provide this info? Been looking at ecu's on ebay. i see used ones. Im just wondering if you could help out whether it be a link to a site or sum to get the right one for my 97 eclipse rs manual non turbo. Much Thanks for all you help.

No, a fuel pressure regulator would not cause a problem like that. Here's some info on how they work:

But a computer should not be sizzling, so that's a strong indication that there's a problem there.

As for buying a used ECU... that's a bit of a gamble. If you go that route, I make sure the vendor has good feedback and a return policy--then be prepared to wait for a while if the part is faulty and you need to return it before getting a refund... and then the down time to order a new one. To get an idea of what the part normally goes for, check with a (non-dealership) parts store. Sorry I can't link to one directly; my job does not allow recommending competitors' goods.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
