I have recently finished my b18c swap intio my dx. It wont start. I am getting gas but no spark wat so ever. I am using a sohc p28 i dont know if that will make a difference. If some one could have some things for me to chekc please leave them. HELP!!!!!

 

break out the mulitmeter, and check the wires to the ecu, then look into a bad dizzy

 

CHeck all the wiring at the dizzy and the ones going to the ecu since you had to do the dpfi-mpfi swap. Make sure all your grounds are being used. The thermostat housing ground is a common one to overlook.

 

So the only ground i have hooked up is the battery ground wat other ground should i hook up and explain where please. Thanx.

 

in the engine bay you should have a couple of grounds going to the chassis. You should have one on the valve cover, tranny, and thermostat housing. I'm not sure about the valve cover or tranny, but i am sure that it wont crank if you dont use the thermostat ground.

 

did he say hes using an sohc p28 on a b18c1, that just sounds wrong...

 

So now that i have the grounds all figured out is a problem to use a 94 sohc vtec delsol ecu (p28) or will it still start and then ill have to get it chipped. basically im wondering if it will start with this sohc p28 ecu?

it doesnt make a difference all that much that ur running a P28 cuz all its gonna do is allow u to hit vtec...but u should get the right ecu soon so that ur getting the right amount of fuel

 

Alright cool thanx im going to try and hook up all those grounds and see if it will fire and then later wat kind of ecu should i get?

 

you mostly likely will want to use a p72(gsr ecu) or get the p28 chipped

get ur p28 chipped

 

alright thanx ill post wen its all done it will end up being a built gsr t3/t4 turbo. thanx for the help!!!

 

So now that i hooked up all the grounds i got spark but it still wont fire up. I am very confused now. I did the dpfi-mpfi swap but am not feeling i did something wrong please give me some info on wat to check!! thanx

 

SEARCH, dont expect people to give you all the answers. top right hand corner click the button that says search, not that my rant is over

you have fuel, you have spark, what about your timing? or compression
