ok my friend has a 97 dx...he is using a 99-00 civic ex harness which is obd2b with a obd2b to obd1 conversion harness...Its ready to be started but the fuel pump wont prime...He thinks he has everything wired up correctly...hes a little confused on the distributor wiring but thinks everything wired correctly...Would the distributor wiring or resistor box have anything to do with the fuel pump priming? any and all help is appreciated...we are out here freezing our asses off trying to figure this out.

anyone have a clue?? ive already searched the h22 swap thread...if everything is correct the only thing i can think of is grounds which are all hooked up and the relay, which was working a week ago the lasttime he drove it before the swap...can they just quit working like that?

No, the fuel pump should still prime. Either the fuel pump is not getting power (via of the main relay or ECU) or the Main relay is not getting power.

Ok, thats what i thought...i guess we are gonna try a different ecu and main relay. Thanks for the help

turn the key on and watch the CEL. If you goes off after 2 sec. You have power going to the Main Relay, if it does not go off, you look into your main relay.

check, double check and then triple check the wiring. It is usually something very simple. Also, try running 12V direct to the fuel pump to see if it is still good. My car was sittil for a few months while i got all my parts together for my swap and once it was all swapped in, my pump would not turn on or primp. I replaced it with a Walbro 255 and it worked perfect. If you are planning to keep a relatively stock swap you could probably get away with a Walbro 190

Lol, man, while i do agree with you most of the time, you would need to have a sick all-motor setup to overuse a 190lph. The 255s are really for turbos, but most people get them b/c they are only like $10 more.

the only reason i went 255 is because I am going to build up my motor quite a bit this year. I also have a modest 100 shot to put on it. I didn't want to worry about fuel delivery down the road. Also, when i was doing my initial research for the swap I was talking to Newman a lot. He strongly suggested the 255.. so i went with it. no regrets... so far.

check ur conversion harness. those are usually to blame for alot of problems. (in my case anyway)

Well, just for your own knowledge, unless you were goign to be above 250whp all motor then you definitely wouldn't need anything bigger than 190lph; however, there is no reason not to get a 255lph if you don't know what you want to do later.

ok, it starts up now...but when you turn the key to prime the pump the relay clicks which brings the check engine light on and the fuel pump on. but the pump or light doesnt go off after the 2 second priming...

Is it a chipped ecu? Does it run normal after it comes on?

Slopoke

Did he rewire the ecu connector that is coming from the main harness?

Because you cannont use a obd2B harness in and obd2A car.
The third ecu connector that comes from the cars main harness will have all the wires in the wrong locations.

BINGO You know where i can find the diagrams for 96-98 and 99-00?

hondaZvic

helms. the civic ETM (electronic troubleshooting manual) covers 96-99. (00 is the same as 99) if u can find the actual manual that is good, if not, im sure someone has one online somewhere.

i have that, just no scanner.. sorry
