check your motor mounts

FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired. Fig. 1: 1991-94 2.9L and 3.0L Engines Firing order: 1-4-2-5-3-6 Distributor rotation: Clockwise

Its not worth the trouble. get the correct engine. The difference between 1994 and 1999 is everything.

bs it is in the back under the seat dont comment if you dont know
remove four screws pop plate off and there it is it took me 25 mins to change fuel pump beat that

99 Engine is OBD-II.

It must match with the same production line ECU.


You may luck out by getting the chip set for the ECU.


Did you purchase the 99 engine,ECU and the wiring set OFF THE SAME Jeep.

The key is to have a matching ECU firmware to drive the injectors and read ALL sensor.

Go to pick and pull and check out few ECU stock numbers and compare to your

==
There is a "S" for stating it's an auto or stick.

The CPS crank position is differnrt between the two.

This can be your major miss-match.

You may need to change out your 94 wiring harness to a 99 to handle electronics not found on you 94 but yes is should work if your computer can (TALK) to your 99 engine

Yes there is a problem with your airbag system. Take it in asap

Ok here it is. Hope you can figure it out.

Yes, but if you don't have a really good diagram for both, you will need to identify each function by trial & error, then remove wires in harness and put them in the right places in the harness plug Use original plug from old seat on new seat.Don't change anything in body harness.
