So the other day when I went to start my truck it took quite a while but when it started it began loping like a cammed gas motor and then the battery light came on and I tested my alternator and it checked out fine so then I went to my battery’s but since I didn’t have a way to test them I just...

Good morning, Gonna try to keep this as simple as possible. About a month ago I was having an issue with my brakes. I found a bleeder seat in the rear right caliper was shot so I replaced it, bled the calipers and all was good. Then a few days later I lost my brakes completely. Only leak I...

So I bought a 99 f350 4x4 6 speed dually. I’ve had multiple 7.3s in the past. All were super strong. When I bought the truck it had a KC S300x turbo on it. Stock injectors and stock tune. It only made about 3 lbs boost at the time. I took that turbo off and put a stock turbo back on it. It now...

Hoping to get some insight on what my issues might be. Bought a early 99 7.3 with trans issues. Vehicle will not upshift into 2nd gear electronically but does manually. Im not a trans tech but work on fords everyday so I checked codes and have 2nd gear incorrect ratio. Fluid is full and clean...

I posted yesterday about the truck (1988 7.3 IDI) not turning over. After hooking it to a charger it started but not happily, then it ran good and sat at 12 or 13 volts for awhile so I decided to take it on a bit of a test drive through town. Well, after hitting about the 3rd or 4th stop sign...

Hey fellas new here and new to 7.3’s but not diesels. Recently purchased the Edge Insight CTS3 and it keeps saying that it can’t read the VIN from the OBD2 port. Any ideas why or has this happened to anyone else?

Hello! I'm new but have been reading the threads and Mark's help thanks in advance for reading! We bought out 2000 f350. Dropped in a new used motor as the old one was cracked. Ran good but hubby drove it before checking the tranny fluid which was about 5 litres low. Noticed transmission was...

240k Miles and no mods. Truck is having intermittent power surges, like I pressed the NOS button in fast and furious, while on the throttle cruising. It happens at idle too and revs close to 1k rpms and bucks when I let the brake off, the rpm is steady while doing this. The bucking happens...

we've had this truck for a while now, it was brought to our shop for not shifting. We replaced the transmission with new. still no shift. we can manually shift it into 1st and 2nd but still no OD. We've had the dash sent out to be checked and rebuilt- still didn't fix it. checked all lights- no...

Okay guys I’m totally at a stop. Here is what’s going on. I bought a 99 7.3 350 SW. one day the starter just keep going till I disconnected the battery. I hooked up a toggle to power the starter with the starter relay on the passenger fender. Worked fine. Found out the fuse panel under dash was...

1995 4700 International LP with 7.3 I lost a drive shaft on the way home with a heavy load. I pulled over and the engine died. It was below zero out so I restarted the engine to run the heater and after one minute it died again. This has repeated several times. It will only run for one minute...

So my PS pump went the other day. While I have it apart to replace, i decided to do all of the hoses. I ordered all hoses from RA. However the 2 lines that arrived don't make it to the cooler? they are much shorter. I referenced the part i received versus what the interweb says :) and i don't...

I can make it shift every time by revving up to 3000-3500 RPM and letting off the pedal. Had ABS codes and I got rid of them all by putting an OSS, Rear wheel speed sensor, and the right front wheel speed sensor, thinking it would also fix the shifting problem. No engine codes or ABS codes...
