just got my car back recently from a tune, it ran fine omw home.

the next morning i go to start it. it starts and then all of a sudden the car goes to a stall, i start the car again and same thing. Then it just doesnt start.

Basically it cranks but nothing happens. i could hear everything firing up injectors and fuel pump, put on my old ignition, check the fuses and checked my cam and crank sensor.

i accually had someone swap out the sensors to see if it was it, nothing.

Do you guys think my ECU is fried , or if it was my COP? Any other suggestions ?

Thanks for your time.

 

Did you check all the IC pipes?

I know it sounds stupid but you never know...

 

yup everything is bolted up and in place lol kinda weird

 

Hmm..I had a similar problem once and it was the immobilizer. Somehow either my key or immobilizer got screwed up and I had to get the key re-programmed to my car. Same thing happened though. Started, ran for a few seconds, shut off, started it back up and shutoff almost instantly, then it would just crank and not fire anymore. Do you have access to ecuflash and cable? You could try disabling it and see if it starts. Or do you have the spare key? Try using the spare and see if it starts.

That's if you did check the obvious first. Fuses, and relays, connectors..etc etc. Don't think it's your intercooler pipes I'm sure it would still start but idle like crap.

 

yeah i tested my spare thought it could be the reason still didnt work.

 

Damn, you hear the fuel pump runnin? Can't be the mass air or IC pipes cuz it would still creep on it's own. It's not ignition... It honestly Sounds like the ecu!

 

yup fuel pump is crankin, gonna try another ecu today and let you guys know .

 

If your trying a new ecu that means you got ecuflash to change the immobilizer code for your key right? So why don't you just try to disable the imm. first before you go and change the ecu...wouldn't hurt

 

After my car was tuned, it had some idling issues, but never had it stall. It would rev down to 1krpm like it was about to, but never did. Take it back to the shop, have them take a look at it. Kinda sounds like the engine isn't getting enough fuel. Did they install a new fuel pump at the same time?

 

If you have spark the ECU is working.

 

no spark and i just got new injectors but i know there kickin

 

ecu is good i tried it on another evo and it turned on fine. also tried another ecu no luck lol BUMP FOR SOMEONE TO HELP lol

 

Have you done a compression check? And your 100% sure cam sensors are fine and all fuses are good? Did you check relays also?

 

I am not saying it has anything to do with the tuner, but I would speak to your tuner immediately instead of posting on here. They should be able to direct you in a better direction or diagnosis since you have already tried numerous things such as the ecu swap and you say you have spark and fuel kicking in.

 

100 percent sure its not the cam sensors i swaped out 3 different ones lol that work good on my friends evo.

deff not the tuner but he is helping me out alot with things and gave me suggestions.

pretty stumped lol maby a wiring harness i will let you guys know, will be checking those out tomorrow.

thnks for everyones imput so far you have been very helpful.
