Thanks for choosing Just Answer . I'm Wolfgang here to help!!Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.
i do need some more info .. i do need a vin # ***** also the 5 digit fault code that is stored in the ecu . thanks
let me see what i can find on the wiring diagram. so the car does not run correct?
ok i need you to inspect fuse 34 to see if it is ok and while cranking do you have 12 volts at the fuse. second the fuel pump relay that you have changed is the last one on the right of the relay panel. can you show a pic of the relay panel so to make sure on it and the pic of the relay and part #
ok when cranking do you have 12 volts at the injector green/yellow wire?
at the fuel injector plug it self . there are 2 wires green / yellow
one wire is green with a yellow stripe. that is the hot wire . use a volt meter and check the voltage at that wire when cranking . it should be battery voltage. DO NOT USE A TEST LIGHT!!!!
let me know!!
ok what happens if you clear the faults do the faults come back after cranking the engine . what happens if you shoot carb spray in the intake and try to start the car does it run and die?
shoot more and see what happens please. carb spray not as volitile. can you measure the resistance of each injector please . disconnect and measure
I wonder if timing belt jumped. When it cranks w/o and fluid does it sound normal cranking?
The front covers needs to be removed and special lock tools needed to make sure it is time
You need the same thing but the one with a hook. You need to take the front to gain access. Service position.
please look at proposal. additional service
