Bypass the fuel pump ballast resistor. @cruiser54

Air restrictor OFF maybe that what I hear on your CRANK/START video. Suggest one more @cruiser54 test: RENIX THROTTLE BODY BUTTERFLY ADJUSTMENT Still as mentions above (@howeitsdone), sounds healthy, sounds like a RENIX.

What is this air restrictor? Air Box w/filter????

On an AUTO that circuit is part of the NSS.

Do your back-up lamps work properly?

Check B+ Latch Relay circuit. Relay supplies 12vdc for IAC Motor via the ECU.

Taken from the 87 Electrical Manual. Circle with F in it.

....oops. I was using the 88 Electrical Manual. No Radio/LCD Clock Illumination Relay. Somehow now I think I've already answered this once. ...oops again. I should know better.

Add 1)Radio, 2)Clock and 3)Radio/LCD Clock Illumination Relay to your disconnect list, then take your measurement to ground. STG could be in one of those components.

Yeah. I was thinking more like distributor cap cracked or the tip of the rotor fell off.

If your sputtering started after doing this, double check these parts again.

≈760torr would be about normal for BARO. Yes. For RENIX 5.3mS-5.7mS for factory equipped and engine at idle, so I'm not sure for HO. For your reading enjoyment. Shows some values. _JEEP 1991 Sequential Fuel Injection Manual_1.pdf

BARO seems low. Not sure about INJ PW, also seems low. Are you up in the mountains?

88ElectManual shows it (Radio/LCD clock illumination relay), but the 87ElectManual doesn't. MJ_1987_Electrical_Manual_1.pdf

You could always buy a mating 4pin connector and just put the rubber plugs in it to seal it.

Vehicle wiring is wired for both the AUTO and the MANUAL. If your equipped with the AUTO trans your TPS would have both the 3pin and 4pin connectors. Since your vehicle is a MANUAL your TPS only has the 3pin connector. NOTE: Both types of TPS's (AUTO or MANUAL) will work for your vehicle. No

Is that for both the front and rear running lights? If front only, double check the grounds on those two trailer light assemblies. Ground through chassis or wired to ground.

Connect ohmmeter between oil pressure sender terminal and battery ground terminal. Resistance should change with change in oil pressure. Note values. I might have a spec sheet somewhere.

I've always like it when a crane does this during its off time. Happy 4th.
