Do you have an update for this?

Yes, sorry I should have specified. The crank sensor was the culprit. The evap was causing other issues. Rough idle, ran like crap when it was cold etc..

Pics are working now! Thanks!

After reading this comment I tried this thread on Chrome, FireFox and Safari. I dont see any pics :( Edit: I click the links and the forum says I do not have permission to view this album.

Pics or it didn't happen!

Put in new Crank sensor as well as the EVAP canister, started like a champ.

So what your saying is, the fuel rail can hold pressure if the fuel pumps are disconnected and I'm cranking it over? So many people are saying ignition related, but there is 0 fuel exiting the rails.

Ya, no codes. Also. starting fluid never started it. It just sputtered some. Also, I ordered a new crank sensor and EVAP purge solenoid, will be here Monday.

I will go try now.

Sorry, I should also elaborate. Its a 4.6L Aluminator with BBR stage 2 heads. MSD COP's Siemen Deca (I think) 48lb injectors, Whipple 2.3L supercharger amongst other things.

Hey guys, it's been a long time! Anyhow. Car wont start. Turns over, very random sputter once every 30 seconds cycle. I am attributing that to my evap purge valve being broken, but I could be wrong. Tried starting with pedal to floor, as well as pumping it. On diablosport tuner, INJ1F through...

Yeah. That's why I said you can not will. Next time I will be more diligent even though I covered alternator and fuses and never used pressure.

Yup figured the problem out. When I cleaned the engine it must have killed an o2 sensor. Then when a friend and I put everything back together (after a minor exhaust update) with new o2 sensors a front sensor connector was accidentally hooked up to a back o2 sensor (with not as wide a range as...

Supplementary question. Are all o2 sensors the same? If a green connector is plugged into a blue o2 sensor is it okay? Or are one more sensitive than the other?

I had a factory green o2 sensor connector plugged I to an extension but the extension changed to fit a blue o2 sensor.

Another riddle. Why do I have a connector extension that changes from green shape to blue shape?

Since it happened I replaced cops, alternator, MAF sensor and o2 sensors. Mostly upgrades but. It had a code o2 sensor stuck open which is why I replaceded them. Never fixed issue. Almost like it's upstream from the sensor. Wot it'll lay strips, but idling and slight accel it lags, it...

Okay, yeah its been a while.. ill look upon what colour the rear is

Hey there. Long time... I am having issues with my car, I think it may be O2 sensor related. It's been so long I can't remember what sensors I rendered useless. Isn't it typical to render the front two out of the tune? also, which colour cable is that, blue or green? Second...

Yeah the car ran like poop. Until it was warm it ran decent then. Just typical bad maf bad O2 sensor stuff. Rich lean rich lean. Mostly rich. I don't have stock motor though.

The upstream sensors are bigger than the rears. The codes I threw were O2 sensor heater malfunction.

So just figured some info out from a friend that's a Ford tech. DY-1039 are front sensors DY-1038 (old pn DY-1058) are rear sensors. I thought I was running front sensors. But some how my tune is using rear "blue" sensors. Which had me confused. Im going to order new tears and be done. As for...

Having issues with them right now. The green connector ones are bigger sensors. Wideband? Upstream or downstream? The blue connector ones are smaller sensors. Narrowband? Upstream or downstream? I thought I ordered new blue connector ones but two green connector ones came in. Took out two...

So I changed the spark plugs and the car started fine. However it threw a code after a short drive for O2 sensor heater malfunction. I pulled two sensors and the wideband and they are pretty fouled. So I ordered two new O2 sensors and a new wideband. Turns out there was nothing wrong with the...

The fuel pressure reads 38. And when we pulled a spark plug it's super saturated with fuel. Okay so we did some digging. There is spark. But we pulled the coil and tested spark plugs and there is very very little spark. We cleaned the spark plug a bit and it had a tiny bit more spark. So...
