does it have a spark?
if the engine light was on...can you give me the trouble code?
explain to me how it quit?
it stopped running three days ago due to a "oil diagnostic light", that is, it ran low on oil
what does it do now?
i am not allowd to call
read the details of what I originally asked, it is all there
and what i have done to correct the problem
did you get any trouble codes?
now the service engine soon light is lit, and will not extinguish itself
no, no trouble codes
when you first turn the key on....does the fuel pump come on for 2 seconds?
ok..the engine light wont go off until it starts
but I have not checked today, it started finally yesterday, and then when i went to change the oil, I started the car, left it to run and warm up for better oil drainage, and it died. now will not strart\
does the fuel pump come on?
it is impossible to hear the fuel pump, but it does NOT come on, the system interupts the signal which allow the relay to power the fuel pump
no fuel pressure for the injectors is the problem,
it should always come on for the first 2 seconds when you first turn the key on
it should come on and go off
unless you are familiar with the interlocking electronics of this car, i dont expect you will know what to do.
the relay that powers the fuel pump is locked out, so it will not run at all when the computers say turn off
but...does the relay come on,,for the first two seconds?
it is never energized when the system is in shutdown, i only7 know this from trying to solve this for the last three days
does the security light stay on?
it does sometimes energize when the crank or start is attempted with the key, but not when just turning the key to "on"
not any more, i am quite good at resetting the security, main, and oil diagnostic computers, all three of them
it is not passlocked
are you close to the car?
i have bypassed the passlock function by installing a 2200 ohm resistor in the circuit of the passlock device
do you know for a fact,,,that the fuel relay does not come on for 2 seconds?
the above bypass worked fine yesterday, the security light doesnt come on
as above, only when turning the key to start
not in on position
ok...so you do have fuel pressure while turning the engine...correct?
and there is no fuel pressure at the distribut9ion pipe for the injectors
no, it would start if i had fuel pressure, and it wont start
all this is after having removed the fuel tank, and the fuel pump and doing tests to determine that there is no problem wen the fuel puymp is ienergiozed
the problem is overcoming or overriding the computer which turns the fuel pump OFF when it wants to
so, like i said earlier, if you dont know about this electronic system, it will be hard to help me
ok...i will opt out...someone will be right with you
Hello and welcome to Just Answer.I will assist you with your problem in a professional manner and will try to resolve your problem quickly.
I have read the posts concerning your problem.
Do you have a wiring diagram for the vehicle?
You really need to follow the diagram closely and inspect everything.
Somewhere along the line the car may have had work done on the wiring and it could be something as easy as a bad connector installed by a previous technician.
It's very time consuming and can be frustrating.
Have you tried to wiggle the wiring harness while an assistant is cranking the car over?
I have seen instances where a mouse or some other critter partially chewed a wire causing some strange electrical problems.
Please post your comments and I will try my best to help you resolve this matter and get the car back on the road.
Glad to hear the car is back on the road and out of the shop.
Electrical problems can really be challenging.
