Civic EG

Okay just swapped in a B18 in my CX
go to start it and it clicks, so i thought my battery was toast.
got the jumper cables and tried again.
now only my dash lights and e brake lights and stuff comes on
no engine, oil or battery lights flash when turned to the on position?
but i did it the first time before?

i guess a have a wiring issue... but where and how?
anyone have any ideas? i turn the key over and i get my main relay clicking and i hear one from the under dash fuse panel too.

What a bummer on first start up!

Make a ground strap from the tranny to the chassis, then on the drivers side make one from the chassis to the head/valve cover.



Sounds dumb, but i've seen this happen a bunch, one ground from the chassis to the trans and the cars all fired right up.

wow you know what! i totally forgot to put that back on!
i got the one on the valve cover but im going out now to do the tranny!

Let me know what happens

WELL wouldnt ya know it!
it turned over!!!
HAHAH WOW didnt think a ground would make a difference on the tranny!

You sir, are amazing

unfortunately it didnt start
checked the codes and it saying 3 and 11?

You are welcome hahaha


3 is MAP sensor. 11 isn't on any list i have seen?

well only have a exhaust manifold and downpipe on it right now
would that cause Code 3 and 5 Manifold Absolute Pressure

and also i have a P75 installed.
would that be the Code 0 and 11 Electronic Control Module (ECM)

Is the MAP sensor on the throttle body? Check the connection, and make sure it is getting vaccuum

yeah its on. but arent those 2 plugs exactly the same?
i may have got them confused?

also can i even use the P75?

You could have it mixed with the TPS?

yeah thats what im thinking.
ill give it a go in the AM

alright i tried to switch the plugs but it didnt have enought length to reach the other sensor so it must be right.

anyways then i bought new wires and tried again, still nothing
that ECU fault code is gone but still have 41.

not sure what is is now?

just checked, im getting spark fuel and air...
it must be something? anyone know? maybe the timing?

tried starting again and just hear a HUGE BANG under the hood!
it was like a freakin explosion, kinda.
think it was from the intake mani.

What the hell is goin on!

wow bro i think you need to goover everything. make sure everything is properly pluged in. and the sound u heard proly was just all the gas in the cylinders from tryen to crank and not fireing and finally it all poped
