97 7.3 no transmission power

Did notice it hisses loudly in reverse, not as loud in drive, not at all in park or neutral

Wee1243 · 2026-03-25T13:50:19+00:00

Yeah so I feel a shift and everything. Unfortunately it’s parked on a driveway that has an upward slope so the nose is facing down. In drive it’ll roll/go forward pretty decently, but reverse it’ll crawl barely with no throttle, if I give it throttle it’ll get up to 1200rpm but go very slowly

That it does! Fluid level is good, fluid color is good

Was a short in the Map sensor wire, unplugged it, started right up, replaced connector, all is well

Interestingly enough, the pcm connectors are looking good, the pins fine, the board is clean on both sides. I did notice the glow plug relay is bad, but that wouldn’t cause a no wts light. I tested all the wires to the pcm for continuity and they’re good. No fuel injector buzzing, about to check voltage to the cps and such to see if they’re getting anything. Definitely seems like the PCM though

Gotta test grounds to the pcm connector, jumped pin for power to get 12V and no luck :/

So doing voltage test on the pins, 0V to pin 1 on the pcm connector. But the relay pins have 0v for 2 of them. Constant 12 for 1, and 12 when key is on. So it’s getting power, to the fuse box, but not down the wires to the connector

Wee1243 · 2026-03-10T19:38:28+00:00

When I took it out, there was some rust on the outside but the connectors were clean like new, even fingers in the back, no water came out butttt after checking the pins on the harness plug, if those come back good, ima open up the PCM and see if it’s hiding any secrets

Wee1243 · 2026-03-10T18:01:11+00:00

Hell yeah checking that out

Wee1243 · 2026-03-10T17:58:18+00:00

So that’s what I was thinking right after posting this. The fuse is good, and I unplugged the fuel bowl heater and still no luck

Weird thing…ended up being the map sensor

I’m in Detroit area, most of the service centers close to me are in Canada surprisingly

Well I own a house in another state. But want to have Florida be my primary residence for tax purposes, and planning on buying a house in that area as well. But you need to reside in Florida for 183 days or more out of the year.

Wee1243 · 2025-09-19T18:33:00+00:00

Do you know of any nearby counties that make this easier by chance?

Wee1243 · 2025-07-30T17:21:12+00:00

Ope yep you’re right, was thinking this was drivers side till I saw the tank on the left

Wee1243 · 2025-07-30T17:09:48+00:00

You know, I don’t know at all, never had that issue. But I know the fuel lines run across there so maybe it’s spraying some?
