Default ej20g crank, no start. flooding

Ej20g from 95 wrx ra, in 98 forester

Fuel pressure is right. Injectors ohm out and were cleaned and flow
Tested. sparks plugs are new. Sparks on all four coils. No cracked
Coils. Coolant temp sensor new and reading proper ohms at ecu.
Maf clean. Timing and compression proper

Might try to start if sitting for a while and dried out.
Then floods out

Help

And I figured I burnt out the injector drivers in my z5 ecu, scored a supposedly good
used z4... alas still too much fuel/not enough spark.

Melted a couple main relays years back before i found the o2 wires fried together on the uppipe. That was when this whole setup was in a 95 coupe

Can a spark be too weak?

Suspecting a weak spark, I ohmed the ignitor. Odd that I read continuity
Only from #2 of the 4 pin side, to each of the pins of the 5 pin side. Each
time it read 130k.

I should mention that I believe this starting problem began some time
ago in the coupe and became much worse to the point of not starting entirely

Yes a spark can be too weak, however in the case I remember, the spark was weak because of old plugs, new plugs sorted it out.

Are the coils in the proper order?

hadn't thought of that. checked and they match up though.

Thanks for responding with an idea. I bet it's something silly.
or maybe that pesky ignitor?

Well I have spark on all 4 coils, but I wonder if it's strong enough. I suppose the best info to have would be to measure the resistances across the circuits of a known good ignitor to compare to my numbers.

1) just found a crack in the flat spot on the MAP
Would this cause rich/no start?

2) does ignitor ground itself through bracket to strut tower?
Possible weak spark if poor ground due to loose bracket?

3) should my test mode connnectors be joined?

I don't know anything about the ignitor but when you say there is no continuity between wires on both sides, that somewhat sounds odd to me.
According to Rob's conversion wiring diagram, it looks like a straight connection. Unless the ignitor is an on/off switch then perhaps that is normal. Maybe someone can chime in on how it works?

So i'm testing my thought to be perfect coil packs. No cracks, no melty spots.

Subaru says 0.7 ohms between the two pins of the pigtail for the primary circuit. And that's good on all four.

However for the secondary circuit, they want 13.8 kOhms between pin one and the contact portion where the spark plug goes. This is where I am getting no continuity. Again this is my finding for all four coils.

As previously mentioned I am getting spark on all four and they arc quite a distance.

Any thoughts community?

depending on your ohm meter, some type don't go over a certain ohm value

do you have a multimeter that reads into the 20k ohm range?

I remember a problem at work were the fluke hand probe didn't read above 2.5k ohm..

My fluke 87 reads into Mohms. And I verified my readings with the nicer fluke at the dealer. Think i'm going to do the coil conversion.
Suspicious readings at the ignitor and bad readings on the coils.
Maybe there is a break in the secondary windings that a spark is still able to jump, albeit weakly

I can hear the eyes rolling to the ceiling, when I call a junkyard asking about wrx parts

Tried unplugging the MAF and seeing if it starts? IIRC there should be a limp mode if you unplug it and it's the problem it'll fire up. I had a MAF stop a 93 WRX cold.

Sorry that was a newb typo. I meant MAP sensor had a small crack, I hot glued it. I swapped MAFs already, but i'll try it unplugged

the coil conversion is pretty easy to do.

now the car runs real good I would recommend it indeed.
