4age wont start/ dies if it does

[skin]

Just bought a car, bought it with the engine not running and I'm now trying to get it going, its a jdm rwd bigport.

Apparntly the morning i went to pick it up he said it started first thing, ran for about 5 mins then died. Now wont start again

Its not getting any spark

help please


Ive checked basics

[Grega]

check engine main relay and fuse to ECU
u got any power to the coil?

[skin]

Yea power to coil just no negative trigger to other side

fuse to ecu is fine.

engine main being the "blower relay" lol

righto ill check that

[skin]

Ok so i went back tonight for anothe rlook


checked the main pins at the ecu

Earth pins are earthed, batter pins have battery

However this pin IGt i take by the information below (gathered from club4ag) is supposed to have a positive signal when the engine is firing.

Can anyone confirm this as this pin has no power on it.


IG t Black/Blue Igniter Assembly Ignition timing signal


The coil has ignition on both sides which I'm sure is how its supposed to be untill the distributor sends a negative signal to the negative side, which it is not doing.

I also have to work out why i no longer have fuel pump working, the circuit opening relay has a positive out put to the fuel pump when its cranking over but its still not operating/priming.

Ahh can anyone help me, I'm starting to think that a dizzy change is on the cards

Cheers

yo

my ae86 book tells me that IGT-E1 should have 0.7 - 1.0 v when idling...

oh the fuel pump doesn't prime either. i got caught out with that
when you flick you're ignition from start back to on (during starting) you'll hear it

[skin]

Hmm well bit hard to test that cause it wont idle lol

Um yea na it dosent even prime when u hit start for like 1 second. Not working. But seems the relay for the fuel pump (circuit opening relay) is working cause it has an + output to the fuel pump wire.

Hmm

[Grega]

sounds like dizzy or igniter might be the issue.
ie: ecu not getting signal from dizzy telling it to fire.....OR....its getting signal but the ignitor is not telling the coil to spark.

u checked to make sure the rotor is actually rotating when the engine is turned over (not a broken cam belt)

[Cuzzo]

check the wiring around the dizzy plug. Sometimes become split and exposed wires.

Been over that thoroughly

mmm i hate cars lol

[Grega]

dude is the rotor button spinning when you're cranking?

[skin]

hinting at a broken timing belt?

I honestly thought to check but forgot lol, havent had it off as i figured theres no spark even geting to it yet lol

[Grega]

yeah
just check first mate.....just to be sure
