Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello welcome to just answer I am master tech and will be able to assist you today.
have you checked to see if the fuel pressure is at spec and also does this have fuel pressure when the car does not start ?
the reason im asking is the D4 light flashes on these when the fuel relay is on the blink.
I had one mechanic check the fuel pressure by taking the bolt off the fuel-filter and depressing the gas-pedal after a stall-out. A stream of fuel shot out almost 12" across the engine bay. He had no pressure gauge to check the the actual pressure to say whether it was in spec, but he told me he was satisfied that it was getting fuel. Do you thing this was not a sufficient check?
well it shows their is pressure
but does not show the system has the correct amount of pressure
you might need to take this to acura to have this looked at since your mechanic does not have the correct tools to work on a acura
when he did this the car was running correct ?
or the car was not starting and he came to the car and did this ?
Yes, the car was running when this test was performed. I appreciate you comment regarding him not having the proper tools to test, but I should remind you that I know the Acura dealer could solve the problem. But, this is a 15 year old vehicle and I need to balance the cost of service and repair with the alternative of replacement. The dealer charges $100/hr to find the problem. Just one day to find the problem, and I've blown the budget, and I have quite a bit of experience in that regard.
ok this will never prove anything this needs to be done when the car does not start.
if you want to fix this problem replace the main fuel relay and drive the car like normal
im 99% sure this is the issue on your car
Do you mean to main gas/fuel pump relay in the fuse box?
no this is actualy called the pgm-fi main fuel relay
this is located in the drivers side dash cover
I'd like to have this part changed out and issue a follow-up if I might. It may take a day or two, but I may have need given my lack of knowledge on this issue. ...I'll be back. Thanks.
make sure to buy this from acura only
Yes, I just found the part: ACURA FACTORY PART# 39400-SV4-003 Correct?
let me check
39400-SZ5-A01 / RELAY ASSY., MAIN
I only see the part number that you've present associated with the Acura TL 3.2 model only. I thought the number I gave was for the TL 2.5. Can you verify?
sorry let me check that
39400-SV4-003 / RELAY ASSY., MAIN so yes the one you got listed above is correct
Thanks. I'll be back.
