Door and ignition lock cylinders
Ωhm replied to DirtyComanche's topic in MJ Tech: Modification and Repairs
Key your locks to a blank key. This way when you lose your keys, you can just buy a blank. No one else needs to know this except for yourself. shhhh. -
88 Comanche SporTruck Project Daily
Ωhm replied to Jeepzahn's topic in Member Projects: Your Comanches
Key on will cycle fuel pump 3-5 seconds with engine off (no crank). 27-31 psi is a good pressure. Pressure should hold and slowly bleed down taking a hour or more. Suspect check valve on fuel pump or leaky injector. As for no change in fuel pressure reading with vacuum hose removed, check hose or the manifold inlet nipple for blockage. Possible faulty new fuel regulator. -

Check out the flat 6 pin connector and wiring above the E brake.

Things that seem fine are not necessarily fine. Do Cruiser Tip 29.

After you clean the rear grounds, disconnect any trailer wiring, if equipped. Also your PARK LPS fuse is 20amp, call for a 10amp. Not saying this has anything to do with your problem, but maybe its blowing a 10amp.

SpaceX, nicely done. two of the three boosters made it home safely.

Don't forget Mr. Sunshine. It will be in your face during the evening heading west, plus driver's window all day long and in your face during the morning heading east. Bring protection.

Hesitation, then dies upon acceleration
Ωhm replied to coolwind57's topic in MJ Tech: Modification and Repairs
EGR has no bearing on engine idle on less EGR valve is stuck open or partially open. Yes, pop and plug the source vacuum line at the EGR solenoid to disable EGR. -
That's kinda of what I meant. Just see it and leave. You'll never forget it. Take a picture.

I'm with Pete, do the Grand Canyon. Make a day for it. It's one heck of a sight.

2.5L throttle stop will shut down the engine. This adjustment is only so that the throttle plate will not get stuck in the bore. Idle control is a function of the Idle Speed Control Motor (ISCM). Note: the nose of the ISCM is the closed throttle switch (CTS). If CTS fails the ISCM will not operate. Keep in mind that CTS could be good but the ISCM is just bad.

Brake Master Cylinder Reservoir Replacement
Ωhm replied to HOrnbrod's topic in MJ Tech: Modification and Repairs
After you swap out the reservoirs, fill with fluid, then apply a vacuum (hand pump) to the top of the reservoir. -

Hesitation, then dies upon acceleration
Ωhm replied to coolwind57's topic in MJ Tech: Modification and Repairs
Starter Relay coil finds a path to ground through the NSS (P/N) switch allowing the starter to engage, so does ECU_pin_C4. ECU_pin_C4 (labeled Start Signal (-)) tells the ECU vehicle is not in gear since it also finds a path to ground. When ECU_pin_C4 is open from ground the ECU will allow for idle speed compensation (kick +50 rpms). If vehicle had started in gear, allowing both starter to engage and ECU_pin_C4 to find ground (No rpm kicker). Starting in gear usually occurs when someone has bypass the NSS or a short to ground on NSS circuit. Clear as mud, right? -
Hesitation, then dies upon acceleration
Ωhm replied to coolwind57's topic in MJ Tech: Modification and Repairs
Renix uses CPS (engine RPM's), TPS (throttle position) and MAP (engine load) for fuel mapping strategy (INJ PW). IAC will hunt and search for desired RPM's if one or more of these sensors fail or are intermittent. O2 will add or subtract time from the injectors, if needed. These are your major driveability components. All of these are parts cannon ammo. P/N can add RPM's (≈50) when vehicle is put in gear. Check this by seeing if vehicle starts in gear. Take cautions here. Also when vehicle dies on the road use N for your restart. -

Since this is a new thread and to save a re-reading of older threads, exactly what parts were loaded into the "parts cannon" over the past year? -

They didn't have chrome thread. Still looks good, great price. Could be more work coming their way. -
88 Renix CPS wiring harness plug end
Ωhm replied to buffalob's topic in MJ Tech: Modification and Repairs
The CPS polarity does matter. It will shift (retard or advance, I don't know which) the ignition and injector timing by no more than 5°. Could this cause a no start, once again I don't know. Flip the wires to find out. What I do know is that CPS connector pin A should go to ECU connector pin C1. -
Runs great then won't run at all....
Ωhm replied to Eye Behold's topic in MJ Tech: Modification and Repairs
Airport issue: I'll assume your running with a working Knock Sensor (KS). The circuit between the KS and the ECU is a shielded circuit. This circuit if not grounded properly is subject to induced ElectroMotive Forces (EMF), hence the reason for the shield. The KS is designed to retard any advance timing during a engine knock condition. Could what your seeing during your airport span be that the timing is just being retarded way more than normal due to airport EMF's?
