Sup yall,
a buddy of mine swapped an h22 in his crx.
he got everything he needed to make the swap work, or so i think.
doesnt start...
replaced distributor, no start.
replaced fuel pump, no start.
very nice consistant cranks, but no start.
we are both stumped, and need all the help we can get.
what yall think guys...

 

check leads and spark plugs actuly got spark, if not try replacing ur ecu, or fuses

 

-Check grounds..
-Make sure plugs on dizzy are in right order =D No Offense
-Check all fuses and relay

 

check the main relay.

 

new ecu, all grounds are good, main relay good, spark on all 4. himself and i and along with other honda gurus' are stumped. we hope its nothing internally... thanks for the help yall. any other suggestions gentlemen?

 

Could the map sensor be broken?

I am assuming you checked the fuel pressure and all that, right?

 

is it a jdm h22 or a usdm h22? the usdm h22 uses an external coil and you cant just plug and play with that. the jdm h22 uses an internal coil like the stock crx motor and is easier to get going.

I had the same problem when I swapped my h22. Cranking but no start. I had to run cut a wire on the dizzy to run to the coil and it fired up and ran perfect.

 

map sensor is good. we replaced the fuel pump with a walbro255, still nothing though. thnx anyway squid...

it is a jdm h22 blackkrixsi. i 'member my buddy bought a new coil for it, but cant 'member if it was external or internal. i can check with him later today. thanks blackkrixsi...

 

Can you hear the fuel pump prime when you turn the key on?

What conversion harness are you using.

Did you leave the resistor box hooked up? The H22 can use the same resistor box as the CRX. You dont need to cut the wires and splice them together like other obd-1 swaps.

 

yeah you can definitely hear the pump engage.
he's using a rywire harness.
its a dx, so no stock resistor.
we are leaning towards timing...
thanks

 

Then thats your problem. The ludes use a resistor for the injectors, without it you wont go anywhere. You have to swap to MPFI when doing pretty much any swap into DX.
