If you have them, or can source them quickly, then yes change them

Iíve done both and had no issues either way ó they are easy enough to change out if there is an issue ó no way I would let not having fresh injector O-rings hold up a project

Yup. Just to remind you, I said "at least" a week to transfer parts.

Re: Engine swap vs shop


I turned it over 30 seconds twice with the fuel relay disconnected. I have a few questions. I didn't start for the following.

-Its flipping late, and she's straight piped, sounds great but I doubt neighbors agree this late.

How long should I need to prime the oil pump?

CEL is on, my guess is from, front clip still off, t case wiring disconnected, fuel relay disconnected???

F""kin thermostat gasket leaked. I didn't use Rtv this time because I read many don't need it., easy fix but I'm none to happy about it.
Ugh

Anyway happy to report the new battery still is kicking hard as it hasn't had much time in the jeep before it got shelfed for the project.

Up stream and down stream o2 connected, no plugs that I can see not plugged in, hope the CEL is of the listed possibllilities.

Your supposed to prime the pump/engine before you install the distributor and before you crank the motor over!

Re: Engine swap vs shop

I just changed a thermostat in my 96 last week -- I did use RTV -- while putting it all back together I knocked the thermostat out of it's seat and didn't notice -- bottom bolt felt a little funny while trying to reach 15 ft/lbs -- of course it leaked

Took it apart and found I tore the gasket with the thermostat being out of position -- still drips a little -- ordered a new gasket and hoses -- gonna do a flush soon anyway


What engine did you end up using? Was it a fresh rebuild or a good used? Never had oil in it?

Re: Engine swap vs shop

Good used engine, which is why I was going the priming route of turning it over with the fuel off.
Better to pull the distributor?

Primed the pump with drill.


Currently I have a no spark issue, test light on ignition coil producing nothing

Check all your wiring ó itís probably something simple

Does your fuel pump run?

Re: Engine swap vs shop

Yes fuel pump primes, the rail has fuel, I've looked over everything I can think of.
CEL light still on, gauges working.

Re: Engine swap vs shop


Wire casing is peeled, but wires intact case was brittle so I electrically taped it, how should I test this as it feeds into the wiring harness?



Ckps and CPS were Mopar replacements, I removed both to avoid damage on the removal/install

Re: Engine swap vs shop

I would work on checking out all your ground connections. Particularly to the block. All that nice paint you have applied may be messing something up. If someone like Mark could chime in on which sensors/components depend on a ground via their mounting point that might help narrow down the field of possibilities.

(Voice of experience: I had an alternator case powder coated (on an older GM rig) and it left me with a dead battery twice before I managed to figure out that the alternator wasn't charging on account of its insulation from ground. An extra chassis ground wire with a star washer took care of the problem.)

Re: Engine swap vs shop

I can't tell if that is black paint on the surface, or if the camera just shows it that way.

A little attention with some 120 grit on a sanding block wouldn't hurt either way. The orange paint looks to be proud of the boss, although the compression of the bolts should have resolved that.
