Hey guys i got my jspec in and everything hooked up but when i go to start it nothing happens. i took the starter apart and cleaned it and tryed it and it works but some how its not gettin the singnal from the key to the starter. All it does when i turn it to start lights dim and clock dims. Please help out on this if you have any ideas i was hoping to get it going by today.

Try jumping it, or making sure the battery has enough voltage.

Josepi

ohh ****....sorry I reread it... Have you tried applying voltage to the starter? Can you get it to start that way?

Get under the car and remove that single wire that goes on the blade connector. Get in the car and see if the lites dim when you try to start. If they don't dim now that the wire is disconnected, then you have a starter or starter solenoid problem. Also check the large power wire is on good and tight and that you have a good chassis ground to the engine. I'm inclined to think the starter solenoid is crummy. You hear no loud clack of the solenoid or you would have said so. Another sure fire method of checking the starter is to put it out of gear, get under with a piece of wire bare on each end. and touch one end to the large power wire and the other to the single blade. The starter should revolve. If not........crummy solenoid or starter period.

Try to turn it over by hand with the plugs out to make sure you don't have any water in the motor. Water does not compress and would make the motor hard to turn over. If the lights are dimming it sounds like you have power to the starter. Either something is binding or there is water in the motor.

I would just remove the plugs and try it again if it spins than it was water in the motor and it should spit out while cranking with the plugs out.

Hey guys thanks i got it to start but not run. but what i did i just took a switch to start the car so now i have push button start but now it dont run right or at all. it remined me of my old car when the back seals were blown, like its only runnin of the front rotor, so im thinking maybe primary injectors. Reason i think this is my car is a 87 turbo 2 and there is three lines all have the same connections going to the primary injectors and what i think is the coolent temp. what im thinking is i hooked up one connection to the coolent temp instead of a injector. Cause when i turn on the igntion one of the injectors (Ithink Its one of them) makes this click click click sound. Is there any way to check those wire and tell the diff from injector lines and that water temp senser? Im gonna post this question on a new thread to try to get some attenchin

Its possible. I just did it on an engine in the garage. The water thermo has a key that is offset, but if you shove a plug with the key in the center on , it will go on. The front primary plug should have a light green wire and a brown wire. The front secondary plug should have a light green wire with a white stripe and a brown and white wire. The rear primary plug should have light green wire with a black stripe and a brown and red wire. The rear secondary plug should have a light green wire with a red stripe and brown and yellow wire.

Hey thanks i'll go look at them but i put differant connections on there cause the old ones broke. you know of any way tellin by voltage or a Ohm meter?

HAILERS

I take it that you do not have the intake off right now. If you did you could just look at the wires and color of the wires that I posted to tell if you have it right. If the intake is on, you could remove the connector to the water thermo sensor at the back of the water pump(I think thats the one you think got crossed) and then go to the ECU. Pull the small plug off. With the key on, you should have 12v at the light green wire with a red stripe, 12v at the light green and black wire, 12v at the light green and white wire, 12 v at the light green wire. Do that and if you have 12v on all, then you did not cross the water thermo plug. What you should do then is pull the intake stuff out of the way where you can see the wire colors and match them up to my above post. You should do this because there is doubt in your mind and it will never be resolved until you do so.

Is it true that the main harness at the end branches off to 3 connections and 4 connections. 2 of the 3 being primary injectors 3rd of the 3 being the plug on the back of the water pump. and 2 of the 4 being secondary injectors?

HAILERS

Sounds kinda right. The two primaries and the water thermo go around from the right side of the engine and go from the left side to the primary injectors and water temp sensor. The two secondaries do not go around to the left side of the engine. they branch off about where the water filler cap is and go right to the secondaries.

are you talkin about NA's or turbo 2's?
