Hello all,
I have been searching the forums and Google for the last to days and am running out of options. If anyone can give advise I would greatly appreciative it !
Here is the story. I have an 00 s2k 130k miles, comptech s/c , AEM V2 , all supporting mods, rc inj 750cc , fuel pump. I got tuned 6months ago and this is my first problem.
So I go to start the car sat after it sat for 10 days and it chuged like the batt was low. So later that day I put a jump box on and it started after a few sec. The next day it started fine , the day after that i changed the oil and it started fine , later that day it would not start again so I put jumper cables on but it would not start only crank. And it has only cranked today as well No start.
So I am getting spark , I can smell fuel and I can hear the pump turn on, my battery is good at 12v, I checked all my fuses , none are bad. I pulled my cam sensors on my valve cover they had oil on the metal part (not sure if that is a sign of a bad sensor ) I cleaned them off but still just cranking. Since I have aem EMS I can monitor a lot of stiff but I don't get cels.

So if anyone knows why it won't start or what to look for on the aem EMS I will be very greatful!

Thanks Eric

 

Just because you can smell the fuel and hear the pump doesn't mean your injectors are firing. Have you pulled your spark plugs? Do they have fuel on them? If so then you can determine your injectors are firing. I'm assuming by your post that you pulled the plugs while confirming spark so I may just be giving you pointless tips lol. I'm not sure about AEM but with my old boosted Eclipse I had DSM link. If the battery died or I unplugged it I would have to reload my tune in because it would reset. This could definitely cause the car to not start because your injectors aren't dialed in correctly. Doubt this is the issue but I would confirm compression too just to rule out the basics. Hope you get it figured out!

 

How many times did you try cranking it over? how cold is it outside? I know with my AEM EMS if it's below 20F it will not start without me jumping it, I will kill the battery. On 40F days like today, If i haven't moved the car for 8 or more hours, it will take me about 6-10 tries for it to start. If its below 20F and I kill the batter after about 25 attempts, sometimes it will take an additional 20 attempts with it being jumped to finally start.

Mine is an 01 with 103k miles CTSC 550cc injectors.

 

Thank you both for the tips I will try to confirm spark by taking out the plugs and check for fuel on them. I don't believe I have lost my tune but I guess my inj could not be dialed in from jumping the car???

When you say cranking it 25 times are you holding the start button for 25 sec basically ? I usually stop cranking after 10-15 secs. It has been cold for here but that's just 40 at night 60 daytime.

Does anyone know what to look for on aem tuner to check if inj are firing? Or that cam/crank sensors are working ?

Thanks Eric

 

Can you plug it into a laptop with the aem ems software? Should then be able to see if the ems is seeing the crank sensor which it needs to see in order to start.
Fuel pump making any weird noises or anything?

 

did you check the simple thing, ignition fuse?

 

It's alive! It was low on battery power so it didn't have enough spark to ignite the fuel so it flooded the plugs, we swaped in my accord 01 plugs and it fired up ... Accord POWr

Thanks for everyone's help ! Eric

 

no, I mean holding the start button for 3 seconds at a time 25 times. It depletes the battery and then I have to jump it until it starts. So far this winter I have had to jump it 3 times, both because the temps dropped down to the single digits. I have been told a tuner can tune for cold weather, I may have to do that when I install my new pulley this month.
