From the begining:
1994 Accord Wagon H22 swaped (OBD I),the bottom end built and driven after 16 000 km. Everything in a working condition. In May turbo build started:
Walbro 255 into the tank, IHI turbo, Tial WG, big IC, some piping, LC-1 WB, Blow Off, Neptune RTP to control all, 3 bar MAP by GM, 450cc DSMs (it appeared they are not working, so 345cc stock for now temporary).

First when I wanted to start a car there was no spark. I thought : OK I fried the coil (it happens, but I'm doubtful now- will check the distributor on my friend's car) as I pulled the plugs from the distributor while ignition was on, my fault? Maybe. I replaced the distributor and finally got some weak spark (cap, rotor almost new, NGK blue wires, fresh ZFR7F11 spark plugs), car didn't start.
Meanwhile I heard some kind of funny noise and I could smell fuel. It appeared one of the fuel lines got rusted so much I didn't sustain the pressure of a new pump and started to leak. OK but what the hell happened to spark? Tried few times and once I spotted the check engine lamp didn't go on when I switched a key... And the fuel pump didn't start to prime at all. It just stopped working. Yeah, what I need is a fried ECU... Anyway I measured the voltage at the distributor plug and it was 12V as expected, I also checked the voltage on the MAP sensor plug- 5V as expected, so maybe ECU is OK? I replaced Neptune with a stock ECU and replaced MAP to stock one. The fuel pump started to prime. OK. No spark though. Another fried distributor? I don't have another to replace... Nor I have an idea what to do...

Help.
Thanks

 

What do you mean by weak spark?

What happens if you pull a plug out, ground it, and crank it? Try all 4 separately, make sure all 4 fire.

 

Weak spark- a spark hardly appear... Now it doesn't spark at all. Just stopped. On Neptune and on the stock ECU.

 

Have you done the ICM wiring test?

Have you checked all the grounds? This sounds like a very odd issue and usually grounds are at fault with something like this....

 

Haven't checked ICM yet. But it is quite strange when they go one by one on two different distributors (if they did- I'm going to check these distributors in the other H22 powered car)
Grounds seem to be OK- I haven't touched them at all. They worked for 16000 km well. but definitely will check.

 

Have you checked the main relay?

 

But distributor has no connection with main relay I think. Anyway it was in a good working condition before. Even now the injectors spray fuel well.

 

Wait now, this just happened out of the blue one day? It was running right before this happened? No mechanical changes/work done?

 

I built the motor and it was running for 16 000 kilometers in NA form. Then I decided to finish the project and turbo it. I haven't touched the ignition system at all but spark plugs. Tried to start the engine, it failed. Checked spark- present, next time cranking- spark not present.

 

for now the coil is fried. Infinite resistance between coil ports. I suspect the second dizzy be the same. All grounds in place.
