ok i have just put a 89 si wire harness main and motor

and i went to start it and i truned the key and the main relay clicks once and no fuel pump goes on
i have never had **** car running
i bought it with no motor and no wire harness

my ecu isn't blinkin so i don't know if it's workin or not
and my engine stays on

there was on plug i didn't put in and it was the one on the back of the motor which is a b18a1 it's a little green plug on the block and i didn't have a little green plug on the motor harness
i don't think that well mess with my fuel pump tho

i have tried to replace the main relay so i took it out of a car that had no motor so i don't kno if it really works or not
it still does the same thing

is there something that i could of not pluged in ??


thanks for any help

 

Is the CEL on but solid?

Try resoldering the connections on the main relay just to be sure.

 

i never even looks at the main to see if it's craked or not

could that be it???

or could it be a ground that i missed and where could the ground be??

steve, when u put ur new body harness in did u plug all the stuff back into the under dash fuse box. i think that may be ur prob. u are not getting power to the ecu.

p.s. sorry i havent been on aol lately im at my dads house and he dont have aim but i will hit u up tommarow. later

 

yea
the ecu used to blink
then i pluged every thing in

but should it blink to show that it's on????

 

You should have a ground from the engine (valve cover) to the chassis, tranny to the chassis, battery to the chassis and the ecu ground is in the harness and it attaches to a 10mm bolt on the thermostat housing. If all of those grounds are nice and secure, then I would look at the wiring to the pump and from the main relay to the ecu. But before you do that, verify the condition of the main relay, even a small hairline fracture will give you problems. So examine each solder point closely.

 

ok i well check all of that
uhm my batt is in the back of my car
but there is a ground wire there
just i don'tkno where it getts bolted to so i just put iton a bolt near the starter

i don't have a ground for the vavle cover so i am just gonna make one

thanks for the help

So what's the status of the car now?

 

the same i didn't work on the car
i took the girl down the shore

so the rex had to wait
i am gonn abe going out rite now to look at the main relay

so later
i'll get make on tonight

 

GOOD LUCK

 

ok i soilder the main relay
and i turn the key and 3 seconds later it clicks
but i still don't hear the fuel pump
what should i do next?????

 

bump

 

yoo bump
help me out

Check the wiring to the fuel pump to make sure it's getting signal. If not look for a short. Perhaps the pump went out on you.

 

do you know where i could get a diagram of what wire goes where on the plug of that is rite near the pump??
becuz i have 2 wires cut
but i think there for the guages that show how much gass
but i just don't wanna put the wire in the wroge spot and expletive **** up

thanks for nay help

 

What colors are all the wires? Look online for the UK/JDM CRX manual, it has all that **** in it.

 

uhmm i think one is yellow and the other one is black with a yellow strip but i could be wronge
i have the chilton for the car just i haven't found it in there yet

 

Black with yellow strip would be power and the yellow is prolly some sort of signally thing. Anyway, figure it out. Try giving power straight to the pump to see if it primes.

 

ok well someon riged it so the pump runs straigh off of the fuse pannel on the inside so i didn't know that but there is the black and yellow wire there
so i am gonna try to hook it up the rite way
but other wise i put the wire in the one fuse and then put the fuse in and i truned the key and the pump just keeps running and never truns off intill i trun the key off

so i don't think that is rite
i think theywhere tring to get away from buying a main relay

i don't know
i am gonna be getting oil and putting my MSD **** on
and theni am gonna try to start it

later
