This is kinda confusing, but here it goes....I have a 97 Base Prelude and I had hydrolock in my last motor and now I bought a 99 SH motor for my car and it doesn't want to start up....I was told by this performance shop who does motor swaps all the time and they told me it should work...I'm using the ECU from my last motor. The motor turns over, but just doesn't start. I also have an ECU for an SH, but when I put that in, it doesn't do anything. Does anyone know what the problem may possibly be? Does anyone have a manual for their car? If so, does it say anything about how the wire harness goes onto the motor?

Thanks

 

TTT
Come on. Someone has to have some idea of what's going on.

 

how did u hydrolock ur motor?u drove a flooded street?

 

I guess no one knows...

 

Long story, but make it real short.....I was driving home one night and it just started raining real hard, and I completly forgot that I had my CAI on that night. (I have my pipe cut so I can have short and CAI intake) As I was driving, I was about 10 min. away from home and then all of a sudden, my car just stopped and all the dummy light came on. I tried to start it, but it was getting no response. I called up a friend of mine and we pulled it back to my house..Few days pass and my friend and I decide to take my motor out and after we took it out, I noticed something by the oil pan that I didn't think looked right. I took a closer look and realized I broke a rod and it went straight through the block. We took the oil pan off and there were pieces of the block and rod sitting inside of it...If I had a digi cam, I'd take pics of it, cause I still have the motor sitting in my backyard...Now about 8 months later, I have a new motor and now it doesn't want to start up...I'm going to keep asking around at these performance shops around here to see what they think could be the problem...

 

u serious?u didnt run into a puddle right?just cruising down the highway while raining?

 

So are you saying that the engine has never started properly after the swap? This should be the problem of the shop that completed your swap, right? They should be fixing whatever is wrong...

I was always told that the Type SH block does not mate properly to a Base Tranny... Something about the intermediate shaft not lining up right or something like that...

I can tell you that your SH ECU is not cranking the car because it does not match the Immobilzer unit in your steering column. The Type SH ECU would need to be re-coded to your car's Immobilizer by a Honda dealer. The ECU should make no difference however... Also, the SH and Base wiring harnesses are the same.

There are only 20 or so other sensors to check. It is pretty hard if the car isn't in front of us. Take the spark plugs out and check if they are sparking. Connect them to the wires and have someone crank the engine while you ground the spark plug. If there is spark, check for fuel. Cranking the motor without the sparkplugs in place would allow you to smell if there is fuel being sprayed in. After that, get a timing light and be sure #1 is firing at TDC on the flywheel, assuming that there's fuel and spark...

 

chanluder>>>I wasnt on the highway, I was just dropping off a friend of mine to get his car at another friends house before I went home, then I didn't realize there was a puddle before it was too late. My car was still going for awhile, and then it just stopped..

oh ok thats what i thought u cant hydrolock ur motor when driving on highways so u entirely submerged the filter into the puddle. hope its running now

 

Nope, not yet..I'm still trying to figure out why its not starting up....It turns over, but just doesn't fire up

 

The motor is good, cause where I had bought it said they test them out before they sell any motor that they have. I put a new key ignition in my car cause the last one fucked up on me. I'd stick the key in, and it wouldn't turn. Same thing happened in my dads car too...

 

We were getting spark from the plugs, but I don't think there is any fuel getting into the motor. My friend and I would pour a little bit of gas into the intake, and crank it up, and it would start just for a second though.. So the problem lies somewhere in the fuel injectors. It may not be getting the signal to feed the gas through.

Check injectors, and fuel pump. I'd also go ahead and put new fuel filters on.

Are you running your original injectors or new ones? New fuel rail or your original one?

I must've missed this thread. Sorry.

 

Make sure that you arent getting fuel before you rule out the posibility that your spark plug wires are on wrong or that the timing is wrong. Because you might be getting fuel and spark but not at the right time.

 

I am guessing check fuel pressure. Then, with the ignition on, check if there is 12volts at all four of the injector plugs. The yellow wire, I believe. Either way, with a voltmeter, one lead to ground and the other testing the pins on the injector plugs. One of the two in each injector plug should have 12 volts. The other is harder to test, it is a pulsing ground when the engine is running. Check all your fuses.........

 

Running the orginal injectors and fuel rail....Everything is stock except for the pullies and cam gears....I haven't touched the cam gears

 

Actually, I've noticed how its not getting the fuel at the right time...After I'd crank it a few times, and quit doing it, I would suddenly hear fuel or something running.

 

All the fuses are good. All the ones in the motor and in my car...

 

fuel pump then?
