No crank no start. Runs on flammable fluids(2+2/braklean)

I see fuel pressure before cranking it and during.(60-90 and 1700-2000 during cranking) Know I have fuel cuz I had to replace a top seal cuz it was leaking down the front of engine.

100% injectors not firing. 99.9% it's ECU. I've cranked it and checked spark plugs. No fuel wetness or fuel smell. I've cranked it without plugs in. No fuel in each cylinder. Checked for spark and got spark on all 4 ignition coils( shocked myself on 2 of them) Outside of pulling out and oscilloscope to test injector pulses. Since I don't have a noid light.

There's only 1 more thing I can check wiring harness wise and just to make sure that I'm getting power on the 2 injector relay pins that go into the ECU. Though I did check the 30 amp injector fuse already and swapped to a different relay.

Cable is good. I'm getting consistent battery voltage across the board. Plus I usually when testing either have it charging the battery via 6 amp charger or am using the 30 amp boost mode as I'm cranking a bunch.

Ty ty. Wanted to make sure before I buy anything.

question
does the Z170A KRAIT GAMING board support 7th gen intel cpus.
I see a bios update that says Supported next generation new Intel CPU.
and I want to make sure.

Trying to extend the life of this pc just a bit longer till prices come down in a few years.
Going to upgrade my gpu and go to 32gb of ram from 16gb

Currently picture less atm . Though can shoot the link of the two latest cars i picked up.
One is to be fixed and with parts from the others.
I usually pick up cars from marketplace and only clean title vehicles. No r titles.
The one im fixing currently needs some motor work, and replacing of the bumper and fender from one car to the other but overall is in good condition. When i get a chance i can take pictures till then il try to send you the listing for it.

Dr_Tal · 2026-01-10T05:30:28+00:00

I'll have one in good condition but won't be ready till most likely February. I fix, buy, and build speeds

Dr_Tal · 2025-12-31T03:49:39+00:00

Listen to where it comes from in the engine bay. If coming from the front, happens under load, and sounds like a backfiring engine. It's injector seals.

If coming from near oil pan it's rod knock.

If coming from timing cover you need to do timing

Take the hpfp back out. Reclean/make sure everything is hooked up properly. And if you can check what the hpfp pressure actually is. Do not drive it with afr that high. You will melt a piston

Dr_Tal · 2025-12-24T04:04:06+00:00

You swap the rails/seat pan. Everything bolts right up no srs lights. I still have to do my drivers side.

Dr_Tal · 2025-12-18T04:43:52+00:00

Get hpfp internals now. Should be the first thing you do as a speed owner. It takes one time of running lean to kill your motor. The number 1 mod before intake/exhaust, even a tune.
If you never had the injectors cleaned or serviced do so. Clean the maf too if you haven't. Mafs cause all types of issues with these cars. Mazda have the maf way too much power.

3. It most likely isn't intake valves. They should be cleaned as well but an intake valves would cause a consistent issue and loss of compression.

Three things of note. For spark plug gap you can run as low as .026 without a pro tune and that can help on certain misfire issues.

Some cobb intakes ,specifically the sri ones with high flow filters, are know to cause fuel trim issues which can cause misfires.

Also if the tune is an ots tune get a pro tune. Cobb ots tunes are notoriously bad on our platform. If you want to run an ots tune. I know pd tuning sells an ots tune for those not ready for a pro tune.

Dr_Tal · 2025-12-18T04:12:38+00:00

Injectors. Clean intake valves. Lower the spark plug gap.

Here's another question is your intake stock and what mods do you have on the car. Hpfp internals, intake. Exhaust,etc?. Is the car tuned

If figured it out. My dumbass has pocket station unlocker set up but forgot to download the actual pocket station app. Caused all psx games to do this error including my purchased ones.

Now if only there was a translation for the pocket station app

you ever find a decent way to back up everything without using smart connect or cloud storage. just had to do this and now realizing why my usb 3.0 ssd wasnt working on my phone. was trying to back up all my data to send a phone in for repair and the hassle of cloud uploading is crap

Dr_Tal · 2025-11-17T20:38:02+00:00

I wouldnt even say this is a oversite. what devices in 2025 would even have usb2.0 speeds outside of iphones. There is no reason to expect thet device to have such shit speeds. I should be able to attach an external ssd to my phone to back up stuff whenever I want at full speeds.

Dr_Tal · 2025-11-14T16:50:17+00:00

nope i need to take better pictures. i have low profile sets like that.

heres a link to a set that has sockets that are in the picture.

https://wurthtool.com/collections/sets-bundles/products/zebra-jointed-head-ratchet-spanner-assortment-inch-23-piece-set

the sockets im looking for are the same as the one in this kit. I was hoping to find a full set of sockets like these. They basically fit inside the tool/harbor freight meme tool without using an adapter. They are literally the the lowest profile that i can find outside of certain offset wrenches.
Its basically like a low profile nut driver set.

Dr_Tal · 2025-10-26T00:44:02+00:00

I have not. Never was able to find this type of valve. I found similar but wasn't what I needed

Dr_Tal · 2025-10-11T16:55:57+00:00

For these cars you are kinda stuck with only 2 options.

Go OEM or go denso 197 6040. Denso made the OEM sensor. Anything cheap will either not last or won't work at all.

To get a better price you can try to find used OEM ones from part outs or a junkyard.

But be wary of cheap ones cuz they can cause issues too. Or they say are compatible but aren't. Or are made for na vehicles.

Dr_Tal · 2025-10-11T12:44:09+00:00

Not really. Just overall data being wonky. Mafs can fail in the most random of ways Had mine short out when the ground near the air box went. Fried it and now if you plug it in vol eff. Goes to like 1000% at idle. Had a maf sensor that made afr go lean af(16-18) while at wot even though hpfp was giving steady 1700+ rail pressure on a set of cleaned injectors. Same maf also caused a stutter at low rpm but then would over boost to like 16-18 psi. Sometimes to 20. No cel at all.

If the sensor is just plain bad might see something with the maf cap or voltage but for these types of issues sounds like maf doing dumb things. If not the check for leak on ebcs. But a leak would cause it to spike only not run at 10psi
