Re: Turbo installl, but car won't start
 

try to replace it with a a/c relay or any 5 pin relay i believe. also use a test light to see if there is power before and AFTER the fuse box, if not after u know ur problem is in the box.eliminate ur options and it will be easier to find the problem.good luck to ya

Re: Turbo installl, but car won't start
 

sorry man that wont work the main relay has about 10 wires not 4 or 5 its a completely different type of relay

Re: Turbo installl, but car won't start
 

Did you check the big fuses under the hood by the battery? They range from 30-50AMPs and are held by two fillips screws/bolts.

Just take it out and resolder all the pins. Worked for me on two cars with same problem.

Re: Turbo installl, but car won't start
 

alright, I'll check it out.

Re: Turbo installl, but car won't start
 

hey guys,

How do you check if the resistor box is still good? I need to check it.
If you slice the deadend clip and took out the resistor box and dsm injectors, and put on the stock injectors do you have to solider back the slice wires?
Or can I leave them cut and just make sure they don't touch each other but putting any end on them.

thanks

If your not getting no fuel no spark It could be the ecu ground on the thermostat housing under the hood, or one of the two engine to chassis ground straps, when you cycle the key does the check engine light come on at all?

good luck

Re: Turbo installl, but car won't start
 

where is the ground for the thermostat housing? I cycle the it and i don't see a check engine light come on

Re: Turbo installl, but car won't start
 

Alright, it check

and there is no check engine light , I think its the main relay, but where is the relay located at on 99 civic si

help

Should be under the driver dash toward the side of the car, on your right if you're laying on your back.

At least I think so.
