I had a bad d15b7 motor in my hatch, so i swapped in a new one i bought off of here. But when i start it up, i have no spark, or fuel. It just whines when i start it up. Like all that is working is the alternator and starter. I checked compression, and it is even across the board but i cant get a spark out of this motor, the rotor is turning and the distributor was my old one and it only has 8k on it. Any suggestions?

bump for you

 

thanks yeah i need help with this bad... .if i dont fix it tonight, it is going to the shop tonight with a trailor. Then who knows the cost.

 

well if its not sparking then you might have bad spark plugs,plug wires,your dizzy might be bad i mean if your other motor was fucked don't you think the dizzy might be bad also?. do you hear the fuel pump relay going off when you turn it to the "on" position? if not replace that. fuel filter might be clogged so it not letting you suck up fuel.

 

awesome ideas.. i used new wires, plugs, cap and rotor. The dizzy is less than a year old. I the fuel pumo relay? You mean the main relay if so, i am checking that today. I have a fuel filter but i havent replaced it yet.

 

Check the ecu ground on the thermostat housing.

 

thermostat housing will prevent spark or fuel? i was prying against it to get off my valve cover. And ecu ground. I never went near my ecu but my car wouldnt even have the starter engaged would it?

 

also check all your fuses just to be on the safe side.

 

i checked all fuses, and all are ok, everyone down to the headlight fuse I honestly am going to work on it when i get off of work, i am catching a ride up to my car. Just trying to get ideas on what to do.

 

had a car like this come in.. turned out to be the ecu was toast.

Try swapping ecu's.

 

so is it still not sparking? updates please!

 

i am going to work on it today at 6:30. I have to what till the guy gets home from work to go to his garage. I think it is awesome that you guys are respopnding. The person who thinks of the solution to the problem gets paypalled 15 bucks! you have my word on it. I need this done.

 

My money's on either the main relay or a missing ground. You'd be surprised how much **** goes wrong on these engines if you're missing a single ground wire. When in doubt, throw a couple more grounds on it and see what happens. Lord knows I've started more than a few swaps by doing that.

 

^^ lol wrd. on these honda its always some thing stupied that messes up the whole car.

 

well i have to valve cover grounds the thermostat has its stock ground and i grounded the tranny to the frame. But i am buying a new main relay and trying a new ecu. Hopefully it will work.

 

i think its the ECU, since fuel and spark is two diffferent things whats the chances that the main relay and dizzy expletive up at the same time. either ecu or ground

 

yeah, but i didnt know an ecu could go that fast. It was working right b4 the swap. And all of a sudden no... i am going to trouble shoot it soon.

 

my distributor's rotor spind but no sparks.

 

I have the same problem . I have a b16a2 in my eg and my fuel pump is turing on and i am not getting any spark. I checked all the fuses and i bought a new main relay. I also switched ecu's. It might be the wires from the main relay. I am buying a new harness. You should check all the wires from the ecu and the main relay.

 

any other ideas?

 

replacing the ecu and main relay... didnt help! any other suggestions?

Did you check your fuses? When you turn the key to the run possition, does the cel come on for two seconds and then go out?

 

no the check engine light never went off. it stays on with the battery light, abs, and oil. I know that is weird but it is just not triggering anything.

Does it have any trouble codes stored?

What is it doing when you turn the key? Is it cranking but not firing, is it making a whirring noise, does the fan come on when you put the key in the on position?

Also, you didn't say that you checked the grounds
