Fuel pressure gauge

Under the steering wheel it looks like a place to plug in a computer. You can take a paper clip and jumper 2 of the pins( I don't remember which two) when you get the right two the check light will start flashing short and long spaces. the first will be one then two that means diognostic mode after that you can take those numbers and look in the book or call auto zone and they will tell you what they mean.

no diagram ,sorry , but usually located in the fuse/relay box in the engine compartment and the cover will have list of which is which

yes it can but more likely it is an internal problem if it is a high pressure. Need to have it flushed.

2 ways you can do it> 1 find the fuse and pull it out but only if it is for the antenna or you can disconnect the antenna wire from the back of your radio, it is normaly a blue wire run with the power harness. Red is 12V. Black is Ground 0V. Yellow is Remote, it works with an AMP if you have one installed. Blue is normaly the power antenna. hope this helps> test it first by pulling the fuse to the radio and if the antenna does not operate then the power is from the radio

what car do you have and maybe i can be of assistance
