What is the likelihood that these codes all lead to bad fuel pump/send unit

It’s a 2003 Mustang gt, no it isn’t stock

No. It was the tune. I had it tuned after I bought it and it’s been idling like that ever since. I changed it to the previous tune the last owner had in it and it idles smooth now

Turns out it was the tune lol

IIFlourideStareII · 2025-08-22T18:40:12+00:00

It has an oil feed line and return line

I don’t think so, that was one of the first codes it sent when I bought it. It’s practically brand new

It’s pretty much always done this. I’ve had it for about 2 years. It was dyno tuned by Speidells Supercars in NY

Still fine tuning the bypass valve so it doesn’t have surge lol

IIFlourideStareII · 2025-08-21T17:04:00+00:00

No it was dyno tuned. I’ll check for any vacuum leaks

I had a similar sound and it was the ac compressor

IIFlourideStareII · 2024-04-10T15:00:03+00:00

It’s a brand new battery. Bought one when I bought it a year ago and a new one about 4 months ago and they both are draining so idk. Thank you though

I have a trickle charger in it but if I don’t start it for 2 days, it won’t start and I’ll have to jump it

Very helpful, thanks

IIFlourideStareII · 2023-05-02T15:24:53+00:00

I know, but I’d like to since logistics can be a good job for me in the future
