I'm gonna work on it when I get off work today and see what I can find out. I will definitely post whatever the problem ends up being. Only way I know to clear codes is to disconnect battery for a...

Light is good. Just a reminder, this is a brand new painless harness. I have the battery grounded to the engine. The engine is grounded to the frame and the frame is grounded to the tub....

Jeep did great on the ride in Knoxville. Funny thing is, when I hook up my scan tool to check for codes, I'm still seeing several codes (O2, map, IAC, ECM, etc...) but it's running just fine and not...

I've got several other things to work on first to get ready for a ride in a few weeks in Knoxville. I may come back to it and see what improvements can be made.

I appreciate the comments/suggestions! I swapped out to another new computer (gotta love warranty coverage). Power is back!!

I agree, the switch is not going to make a difference. I threw it on anyway and swapped out my fuel pump back to the carter p5001 tbi pump. Adjusted my fuel pressure up (he recommended 20 psi -...

The mechanic I took it to says I should have it. Called Painless since I have their harness and he swears I NEED it. I guess I'll pick one up and throw it on. Mechanic also said my fuel pressure was...

I have a scan tool but didn't realize because it's an OBD1 I can't look at live data or freeze frame. It idles fine. As soon as you give it throttle in a stationary position, you can hear the...

Thanks Ony! I first replaced the ignition module in the old motor to no avail and since have dropped in a new distributor, which I reused in the new motor.

Thanks for the insight 1project2many! I hope to shed some light on things when my scantool comes in tomorrow (and I learn how to use it).

Already checked the injectors. All is good there. Just ordered a scantool. Should be here on Saturday. Thanks for the help so far!

Sorry for the confusion and thanks for cleaning up my mess! I should have elaborated a little further. This was a new long block and ALL sensors have been replaced with new ones, new injectors,...

I've been off-roading for over 20 years and had several modified Jeeps with various motors. I recently purchased a Jeep CJ7 that already had a 1993 Chevy C1500 TBI 5.7 motor in it. Guy who had it...
