Check List ...

Post by Bantum » Wed Dec 10, 2014 8:43 pm

There's a few things to check :
  • How old is the Battery ?
  • Battery holding charge correctly ?
  • Alternator OK ?
  • Do you have a relay to the Starter ?
  • Faulty / corroded wiring ?
  • Bad ignition switch ?
  • Earth leakage ?


Could be any number / combination of these ... ;)

Ciao, Bantum ...

Alternator is charging at recommended voltage. battery is good was on trickle charge prior to refitting timing kit. no relay to starter (not needed) wiring is good.

If you listen I'm sure there is a relay clicking while the engine won't start. which on the second start dissapears when the gerchug gerchug gerchug starts.

I've changed the ignition relay but I need to wait until tomorrow morning (when it is cold) to see if that solves the problem.

Could be your starter solenoid Jules. My old van one day did a similar thing. Then over the next few weeks it got to the point of spending half an hour clicking away. I pulled it apart and silver soldered the contacts back up and it worked flawlessly thereafter. Could also explain the weak cranking power because all the power for the starter goes thru the solenoid. If it does it again try a screwdriver across the solenoid and see if it cranks normally. It probably only does it in the cold morning because the battery is cold and cant put out the amps like when its warmed up from the engine and the sun out in the car park.

Ok this afternoon it cranked and cranked and wouldn't start 3 times without a start then on the 4th try away she went.

Im going to try another starter and another battery.

I have a sneaking suspicion I could have an unhappy fuel pump. :(

I dont think a bad fuel pump would cause the sluggish cranking ;).

Yeah ok Doug :) the battery was the problem (I hope)

I swapped the battery from my brumby in this morning and no slugish cranking, yet the battery from the vortex works fine in the brumby.

I guess even though it was holding charge, it was discharging too quickly on cranking causing the problem (good theory Doug?)

Or a bad connection fixed when you swapped batteries?

Could have been but I doubt it, as the battery was on charge for 2 days before I put it in with clean poles and a clean positive and brand new negative clamp.

the battery from my brumby is a calcium hybrid (no idea what that means) and it has 400 what evers of cranking power. the vortex battery was a normal job with 400 what evers of cranking power (my very technical unit of what evers :) )

I would say the vortex battery, now brumby battery is getting a bit long in the tooth at 2 years old :)

So I like testing my cars to see just how well they go :)

About 10 Kms from the Preston beach south entrance (I think)

THe biggest problem I had was the fuse holder for the thermo fans melting down from too much draw. Oh and my wife and kids screaming with joy? as we hurtled down the beach in Jetcar AKA the sand rail.

I think I need to put the lower air dam back on to try and stop the sand castles that were being built in the engine bay :)

So it seems with the new year the vortex has decided that not starting is a good idea.

questions asked and answered many times :)

Please remember this is an EJ22 conversion not an EA82

what condition is the fuel pump in? both fuel pumps work I swapped out the working aftermarket pump back to the Subaru pump which works.

How old is the Battery ? ... less than 2 years old so was the other one I swapped it with.

Battery holding charge correctly ? ... yes I can crank the starter all day both batterys hold charge.

what condition are the battery terminals and clamps in? the battery terminals and clamps have been cleaned

What condition are the positive and negative battery leads? 12mm copper leads from a late model liberty.

Alternator OK ? I changed from 4 wire to later 2 wire model and it is charging at 14+ volts

Do you have a relay to the Starter ? no Don't need one as the starter cranks every time.

Is the starter in good condition? I have a reduction starter. I pulled it apart this morning and cleaned all the carbon out of it, the brushes for the motor are near new, as well I greased the bearings and gears for good measure

Faulty / corroded wiring ? wiring has been checked and is jn good condition.

Bad ignition switch ? ignition switch is good (so is the spare)

Earth leakage ? all earths tested no noticable leakage

injectors not tested but can be heard ticking away nicely when the damn engine runs.


Is the igntor working? Ignitor checked and the spare was checked as well both are working units

Is the coil pack working? coil pack checked and the spare was checked as well both are working units

the EJ starter circuit and fuel pump relay the orange / yellow jadeco relay (one of 5 working units) works fine as does the other round subaru relay for the ignition(one of about 10 working ones)

upper cylinder cleaner used about 4 months ago.

injector cleaner less than amonth ago.



Sensors checked and replaced with known working units

AFM, IACV, Crank AS, Cam AS, Knock sensor, O2 sensor (new one in the mail) Water temp sender is brand new from subaru.

All sensors listed have values with in range at the ECU (was fun to check)


now I have a question ...

will a faulty TPS stop the engine from starting?

according to the error code section the ECU should supply a value if the TPS is faulty so the engine starts (but runs in limp mode)

My engine just floods and won't start. must bang head against fault line :(

Forget about the starter, if it turns over it, the battery, the cables, the clamps are all doing their job, The alt is only to keep the battery topped up, so forget about it too.

Are you getting ignition? - at the plug? if so, are you getting ignition under compression?
If you are using NGK plugs, try champion, they are more resistant to shorting.

If you are confident ignition is fine, how old is the fuel? doesnt take long to go off, especially if it is an ethanol blend
Have you tried giving it a 'cup of tea' down the throttle body then cranking?
The trading corner : the stuff that I need ATM -
# Vortex Main Dash Surround / Bezel ANY COLOUR,
# Vortex Radio, # RHD Vortex 4speed auto digital dash,
# RH-Side parking (86+) Vortex wiper transmission,
# EA82 AWD 4EAT,
If you have them please PM me :cool:

Time to replace the ignitor?

Only ask as it seems that you don't have any spark if it's just flooding.

I had an issue with the TPS unit being a part of a problem with starting and poor running. At the same time I replaced the knock sensor and temp sensor. The TPS was replaced with a cleaned out second hand unit.

But I was still able to start it with a lot of effort.

Are you using the EJ starter circuit in the conversion?

It is possible that the TPS could stop/make it difficult to start the engine.

I'm using the correct AC delco platinum plugs.

fuel is less than a week old as stated it floods and won't start

I used start you barstard to get it home yesterday this morning it just doesn't start. even when given a squirt.

Igntor was tested and replaced and tested I added that to the post along with the tests for the coil packs.

every sensor has been tested or tested and replaced apart from the TPS

which I can't test until my new voltmeter arrives in the next 2 weeks :(

Yes I'm using the EJ starter circuit and fuel pump relay the orange / yellow jadeco relay (one of 5 working units) works fine as does the other round subaru relay for the ignition(one of about 10 working ones)

I've given up for today as it gets hot in that car in the sun.

If you want Jules your welcome to bring it around some time and we can have a look at all your signals with my scope, make sure they look happy.

If its flooded, spraying more fuel down its gob aint gonna help. Try cranking at WOT, if the ecu is smart enough it will realize your trying to clear a flood and turn off the injectors.
