ive had my PFC for a bit with no problems. i just got back from deployment and my friend was watching the car for me. He tried to drive on day and it was sputtering badly. i returned home and found 2 Vac hoses off. Fixed that, and tried to start the car. No Joy, it just turns over. Checked all fuses and found 2 bad (Eco sensors under the hood. 30amp)
Changed, and still no start just turns over.
Any idea what else it could be??
Crank sensor? Coils?

Ive gone through ever process i can think of except for changing these items.

 

Hi

Is the display still showing on the commander as the battery/jump start or replacing fuse can spike the ecu and blow a fuse in it and this will stop the fuel pump from working and you will lose your map.

 

Everything still works on the commander. All sensors are good, all fuses replaced 2 days ago, and i checked again yesterday. Reset and installed the settings. Everything looks good with the ECU. Fuel pump primes, and can smell fuel when trying to start. Just not getting Spark. I dont have a CEL light or anything like that.
I think it might be a Relay, or the CAS sensor.

 

Is it possible for something inside the PFC to Bad. Checked plugs and getting spark on 1&3 nothing on 2&4

 

Check to make sure that you are getting 12 volts to the coil packs......could be a bad IGN relay.

 

yup i just thought about that too. will check when i get home. got another problem to deal with now. My fuel pump is dead i think. No Prime, all fuses good and all relays replaced.
sounds like time for an Overhaul

 

Yeah you always have **** like that to deal with whenever you park a car up for a while.

 

yeah, tell me about that. im still working the issues now, Gota get the size 8 for the fuel pump.

 

Did you ever resolve this issue? I'm having the same problem.

 

any news solving the issue...

 

I fixed mine, was the crank position sensor.

 

sry to bring up old thread, but to close. It was the fuel pump. since it sat, i had to turn the over longer then normal, then it just fired right up. I found this in another thread here. Tried it, and it started.

 

Do you know if this works on the EVO 9?

 

It should. cars are basically the same, just some sensors added for the 9.

 

was it easy to change? gotta do mine, pulled cam and crank sensor code.... let me know
