While my prelude was running I had my hood open beacuse I installed new battery and As I was sitting in the car Iwas looking at the battery and I seen sparks from the positive wire or the battery and my car died . so I went to check it out the positive touche the intake and frame .(bought the wrong battery so the claps where on the side not on the top.)and my car wont start has spark feul pump good coil good compression good Ichecked the *** boxes all the fuses are good what can the problem be ?

 

you blew your IG or ignition 50A fuse in the under hood fuse box I have done this once and that fuse almost always goes out. Check it and get back to us. Here is the pic of what fuse I am referring to circled in red:

 

But the fuse seems good

 

Seems good or is good? did you take a long good look at to make sure its intact and not broken in the center? Its either this fuse or another fuse in your interior fuse box like the other ignition fuse or something in there.

 

I took the fuse out and its not burned and I checkeed all my fuses under the dash and non are burn

 

if you didnt blow any fuses then i would be concerend with the ecu. Try borrowing another ecu to make sure you didnt fry yours. I have done this once wheni was trying to boost a car, i shorted it out and it freid the ecu.

 

Did u get new evil after or you bought it used and how much do they cost

 

Ecu*

 

It was in an accord and at the time i got a repalcment ecu from a breaker for 75 bucks. Depending on what ecu you need they can range form 50 to 300 bucks.

What ecu are you using?

 

If you need an obd2 ECU I have one for you, just let me know.

 

how much you asking for it?

 

I paid a bit of money for it and only used it twice to run my car, it does not have the immobilizer in it so it will start and run any prelude with a obd2a ecu plug ins and an h22a engine of course.

 

How much

 

Just make me an offer on it, it is a JDM ecu so might be what your looking for

 

Is that a obd2a or obd2b

 

obd2a
