evo no start
So I have this weird issue that just happened. I got my new HTP 6466 on the car everything ready to go to be tuned so I go out put a full tank of pump 93 in the tank and of course my last tune hates pump gas and has a hard time starting. I get the car fired up and get it home to park for a few days while I wait on my tuning apt.
Day of the apt guy remotes in and car will not start. Ok put my old map in there no start. Ok wtf is going on. Tuner gets frustrated that I'm basically wasting his time and ends session. Ok great now wtf is wrong with this thing. Fast forward to a week later when I have a short period of time like I do everyday to look at it.
No fuel pressure. Ok great 2 brand new 525s go in tank that job is done. Try to start the car pump primes no start. OK wtf so I dig into it a little more. Comes out to be that I have no spark, no fuel but my pump primes. Any suggestions? I looked to see if there was any blown fuses and nothing, It is odd to me that I have the pump prime but my plugs are dry after I crank the car over. And what confuses me even more is no spark at all and all I did was put pump gas in it and drove it home. I am thinking maybe crank trigger but I see rpm when I crank the car over so idk if I can eliminate that. Thoughts?

In regards to the no fuel/spark. That is odd. Especially since it was working before. Something electrical is definitely going on relating to spark/ignition. Could be a crank sensor maybe? Double check to make sure all connections are not loose. Fuel pump is priming, but injectors aren't getting signal likely to pulse/provide fuel.
Hard to read your mod list from my phone, but are you on speed density?

Sounds like you need to find another tuner lol. Unless he is tuning for free, that throws red flags to me.

Ok this is starting to **** me off. I did find my multimeter, it was right where I didn't leave it for whatever reason. Anyways I have continuity from ground to all the ground pins on the ign1a coil (# 1 coil) and Idk what the voltage is suppose to be to the power side but I do have .008 with key on so there is voltage there. I am at a loss idk what to do. I tried to crank it over again and pulled a plug and plug is dry but I can smell gas so idk how that is. I am starting to get pissed.

I switched from haltech to stock ecu a couple of weeks ago, and it wont start. I checked all the fuses and batt connection but it still wont catch. I switched on my extra batt, tried flooring the pedal, released tank pressure and added fuel into the tank and finally it started catching then dying. I think it finally ran on the 5th try.
I noticed that on my SD tune the idle table >500 are zeroes so I put some values in there. that seem to help when feathering the clutch and the idle is dipping below 900

while doing a pull on haltech, my car popped a fuse apparently (&@#!!%$! busy street). its one of the 'engine' 10A fuses under the dash (i know you checked yours already). the shop said its the fuse to the ecu and that it popped because the o2 sensor was drawing a lot of current. everything worked, the haltech unit even has its power light on, but it just wont start
