Ok so here is the deal i just swaped a b20 vtec into my 00si and when i try to turn the key to the on position, to prime the fuel i get nothing. Just the brake light comes on. and then if i try to start the car still nothing besides the cooling fan starts up. I know the battery is good and my grounds are good. i am using an obd1 ecu with the proper conversion harness. what could my problem be?

 

check all your fuses.

 

will do, any other ideas?

 

grounds? ecu? and make sure your main relay is good?

 

i dont have the fuse covers which one is the main relay and how do i check it

 

Get a meter and troubleshoot.





EDITED: My fault - posted the wrong schematic...

 

ok i will do that also

 

still nothing i put a known good main relay and still nothin

 

$100 says its the TRANNY GROUND, i had the same problem before.

 

THANKS A MILLION...had the same problem as same guy above, but now solved..Tranny ground plays a big ROLE!

 

Where is my $100 LOL

hahaha

 

wrong guy i am the one that started the thread. what should the maximum ohms be between the batterry and any given ground?

 

Doesn't really work that way. You'd be more interested in the max. voltage drop across the individual ground cable....which is something like .01v.

But if grounds are something you suspect...clean'em. It should be a part of normal maintenance. There aren't but what, 4 or 5 of them.

When you click the key 'on', do the injectors/ECU get battery voltage? If they don't, troubleshoot that first. The ECU needs battery voltage in order for it turn the Fuel Pump Control wire on to activate the fuel pump.

What ECU are you using? I only posted the schematics for the 99Si since you didnt include more info with your original post. Not all ECU's use A16 for fuel pump control...

 

i am using my 00si ecu but i also have a p28 and conversion harness. what pin is the power to the ecu

 

possibly neutral safety switch. just a guess

 

nope already checked it but good guess

 

i know i might be retarded but can someone point out to me which one id the power for the ecu?

 

could be the ignition switch or the harness that it attaches to.

 

ok i fixed it the connections that the grounds were made out of were not very conductive

 

 

so i take it was the grounds?

happened to me too. Fixed ground, good to go

 

YO, where is my money? LOL
