Hi;

Having probleme with my car,

Started it in the morning, went to work, parked it, and when i wanted to start it at night ... Nothing happen!![ANGRY][/ANGRY]

engine turn, -quickly enough as battery nearly have 3 month- but doesn't want to run !

 

I don't hear the fuel pump, what could it be ? I'll have a look at the fuel pump ecu.

 

Started very well, as every days in the morning, never had issues with the car !

 

Please HELP!

If it's a stock pump you probably wouldn't hear it. I would check for error codes first, then the obvious, has it got fuel in it, pull a plug and check for a spark etc.

Hi, thank you for reply.

 

So worked on the car at work, at lunch time,

1st try: done the 12v mod (fuel pump controller)

the car started well after that , (was 12'clock)

Started fine at end of day; too. went to my mate's ; and there when i had to go ... ...nothing.

car won't start !!

'til now still don't want run.

>No fault code

>Fuel pump running

>battery ok

 

 

i didn't put the fuel pump controller back after the mod could it be a probleme?

*#$:(

She did it again ... drove it all night yesterday & this morning, started well numerous time. I went to the gas station to fill up the thank and she didn't not want to start (that pissed me off)

tried to look at the probleme but she never started. had to let it there and now after my day of work i'm going to see what's going on.

 

Thing is ;

it started yesterday when i plugged back the Fuel pump ECU, so i tried many time with ECU plugged & unplugged.

plug in : ok

unplugged : not ok

so i tough i solved the probleme by bypassing the ecu . but not !!!

 

Does anyone add issues with fuel ECU???

Should be something playing up

car started this evening , she stayed all day at the gas station, i know well people working there.

Fuel pump ecu was disconected i plug it back and she started.

took it back home to do some try tomorow

all that checked when the car don't start

 

Here is the list you should check:

1. Fuel Pump relay : ok

2. Fuel Pump regulator and filter : should be ok as i think that it's an electrical issue

3. Fuel pump ECU : need to check

4. Coolant temp sensor : no to check ; but i don't think it have a play in here (i may be wrong ) 5. Gounding point : ok

6. Fuel Pump : ok

7. crank sensor and cam sensor if neccessary
