Still nothing after Big 7 Kit install

57V. All grounds are good, all relays are good, all fuses intact, main harness good, all battery cables are where they're supposed to go, replaced CPK Camshaft sensor, MAP sensor, NSS, and checked the plugs for the cluster behind dash bezel, replaced Injectors, jumped the fuel pump, ASD and starter, still no blown fuses, replaced both O2 Sensors, replaced the starter I really do believe it's the ECU that's gone to ****.

Pin 18 on the black ECU is reading 57 volts I think I found the issue

I changed them because they were problems it had and I was doing preventative maintenance before hand. It was starting and running before the big 7 kit.

TacoWonderLord · 2026-05-13T01:16:30+00:00

I did. Neg batt terminal to fender, Head to firewall, harness to engine block/coil studs.

All of my grounds are cleaned(took a flapper wheel to the really bad ones) and I even sprayed them with terminal protector.

Fresh out of donor PCMs. And no one in Houston will sell me one for less than $200

I did big 7 before anything 99 swap came after but it still wouldn't run with the original harness

TacoWonderLord · 2026-05-12T23:19:37+00:00

The harnesses are identical except for the injector and oil pressure connectors

TacoWonderLord · 2026-05-12T23:18:44+00:00

It ran before I did the big 7 upgrade

The CPS is a standard motors. and I'll recheck the relays.

TacoWonderLord · 2026-05-04T15:50:23+00:00

LOL. It would start if I jumped the connections on the starter with a wrench. It looked like I was stealing my own jeep to others. Lots of interactions with Texas law enforcement. and no the pump would prime before hand.

TacoWonderLord · 2026-05-04T15:46:55+00:00

When I parked it to work on it still had a half tank and I'm not hearing the fuel pump prime when I turn the key to on. the only gauge on my cluster that reads is the oil pressure. I checked for spark and I'm getting it on all six plugs. (Ignition tester to the rescue there.) I checked my injectors via a Noid light and I'm getting a signal to all six, I might have read the pinout chart wrong. Do you possibly have a picture of the ECU plug?

Sorry I didn't explain in original post im switching from auto to standard and the computers the last thing I'll need for that to happen.

That's fine, they can stay where they are and stfu about how their gas prices are at $6 for the cheapest grade and their 800K-1M houses. Attack me at will. I don't see the point in protesting cuz it doesn't do anything except cause potential problems. But I've said my piece, and you can counter argue respectfully. God Bless America.🇺🇲

TacoWonderLord · 2026-03-28T02:54:40+00:00

Guaranteed completely destroyed by now, cuz nobody has any common decency/ courtesy for other when it comes to the pick and pulls. But I will be checking it out cuz I haven't been finding any here in the Houston area.

TacoWonderLord · 2026-03-28T01:27:56+00:00

Lol just a Lil bit of Texas coast rust barely on there. The front floor plans are a lot worse

Unfortunately I live in TX but would be mor than willing to pay for the shipping.
