Icon9 Timing belt issue fried my ecu

Its a long story make it short.
I got a 98 prelude. took it to the shop for timing belt change. then took it home to days later the timing belt shreded. tow it back to the shop. they replace the timing belt. but the car won't start. they found out my ecu fried. how? they put an integra ls ecu in my prelude an it starts right up. now I have to get a ecu and program it. this only the dealer can do. Took it to the honda dealer have them order new ecu, red key, and reprogram the ecu the car won't start. then I tow the car back to the first shop that did my timing belt. put in the LS ecu it starts.
CAN ANYONE HElP PLEASE?

Double posting FTL.

Anyways....What does the car do when you try to start it while running the stock ECU?

Re: Timing belt issue fried my ecu

the car just crank the engine turn over but it won't start with the stock ecu or the new reprogram ecu from honda it will only start with the Integra ls ecu?

Re: Timing belt issue fried my ecu

Make sure it's getting fuel and spark with the stock ecu. Sounds like it's not getting one of the two.

Is the LS ecu stock or chipped?

Re: Timing belt issue fried my ecu

This doesn't make sense. There's gotta be something wrong with the P13's you're trying to use. Bump for help.

Maybe I'm just an idiot and I'm missing something.

Re: Timing belt issue fried my ecu

Ok, maybe this doesn't actually help much, but if you take your car to get a timing belt fixed, which is supposed to last 80,000 miles, and it shreds after two days...why would you take it back to the same shop?

And after that, they fix the timing belt, and when it went in it started but it came out and it doesn't...kinda sounds like a shady and/or incompetant shop.


Anywhoo...ECU's can also be vulnerable to static electricity, like very much so. Thats why they are kept in anti-static bags and the person installing them should be grounded. Its possible someone touched it with a bare hand and a little static shock hit it. Thats pretty much all it takes to fry an ecu.

But kinda doubtful. I would just take it back to Honda and tell them to make the **** work.

Re: Timing belt issue fried my ecu

I don't really understand how the ls ecu is even running you car, get the ecu code for us it should be on it somewhere. If i were you i would recheck that timing they did and chances are they fried your ecu, they don't just brake for no reason(especially when it was fine previous to taking it there), normally they get shorted out or something along those lines. the whole thing sounds really shady to me to be honest i would have made them pay for the ecu since it was running fine before they got it and who knows what kind of damage your causing to the engine by running a ls ecu on it. you could be running lean and not even know it dangerous stuff to mess with unless you like melted parts in your engine.

Re: Timing belt issue fried my ecu

Ya my engine has been running lean for mad long, I'm not even sure if its worth it to replace the ecu as the engine may be too far gone.who knows? anyway its best to leave the ecu stock unless you know what to do when tuning it and get it done right, etc. Also, I would make the shop pay for that ****. If it started going in, it should start coming out, ya know?

Re: Timing belt issue fried my ecu

What boggles me is that when the timing belt shredded, it didn't bend the valves...

...and furthermore, I can't conceive any possible way that anything related to mechanical timing could "fry" your ecu.

I don't know either but is it possible if the timing belt is off or is snap can fry the ecu?

Re: Timing belt issue fried my ecu

dude...thats quite an unusual problem. If I were you I would not have taken it back to the same shop...like ever again. Two days after they installed it brand new??? I'd say they didn't align the timing belt right, or just put a plain crap quality timing belt on it. and Yea, take it back to the Honda dealer and tell em to make that thing right. You might research some other aftermarket ECU's and some prices on ebay....and make sure whoever you decide to buy from(if you do) is a top-rated seller, and not somewhere out of the country.
Anyways, where you stays?
