18rgeu cold start problems Sun, 25 May 2003 00:33 Go to next message
Hi there,

My 18rgeu doesn't like to start in the cold. The main reason went to EFI is for the better start in the cold. I am not sure if the cold start injector is working,(not sure how to check), or if i have wired it up right. If anyone has had a problem with this can you let me know. And if anyone know of someone to take it to to have a look at in Brisbane can you point me in the right direction.

thanks

Hey blaze - when its cold get your multimeter and back prob the cold start injector plug. start the car and make sure the injector gets 12v and times off after a short period.

The cold start is controlled by the cold start switch next to the coolant temp sensor. ones green plug and other is brown, not sure which is which.

you should have ignition supply to one pin on the cold start injector and also to one pin on the cold start switch.

The other pin on the cold start injector will go dirrectly to the cold start switch.

The body of the switch is where the earth is triggered to.

Hope you can work it out from that.

Another option is to unscrew the cold start injector form the manifold (plug the manifold with a rag), get a glass jar and place the injector so that it sprays into the jar. Get a mate to crank the motor and see if the CS injector is working.

I'm not sure how the 18RGEU setup works, do they also use an Air Bypass Valve?

Cheers
Wilbo

Well I didn't see this coming. I found out that the wire i thought went to cold start injector was not it at all. after fiddling around i found it. and got things going. but it only started when things warmed up, (around lunch time). Drives fine after you start it. But was a bit weak in places. Now i know why!

It did the same thing again the next morning. Got RACQ out to have a good look over. I was going to ring around and find some one to tune it properly as soon as it got going again. Anyway the bloke tried a few things and then took a look at the suction through the air intake. Very weak!!

He did a compression test and it had nothing Shocked Shocked

So I guess that would explain why it won't start in the morning. and will when it warms up. Time to take it off the road again and rebuild it. Serves me right for trying to do it on the cheap.

Hi. I have a similar problem with my 22re engine. It takes about 5 goes to get going in the morning and starts fine when warm. Was just wondering what did you do to solve the problem you had?

Hi,

You should of stayed with the carbs.

If they are properly tuned and set-up - and I mean properly by someone that knows what they're doing - you'll not have any cold or warm starting issues.

There appears to be a lot of misinformation regarding carbs are poor at cold starts. Well, yes they are if they're not properly tuned.

my cold start injector isnt even hooked up. the biggest problem i have whith my enging is it has no electronic idle control, so running cold is a bitch.
my ecu is just tuned to pour lots of petty in when its cold. dont see the difference in using the cold start injector.
