I just got back from vacation and started to work on the jeep again. It was recomended in the last thread that i check the distributor re-indexing/spark path to try and fix my problem.
I am satisfied with the distributor index, and the firing order i had in the hayes manual was correct 1-4-2-6-3-5.
But... the firing order cast into my intake manifold is 1-5-3-6-2-4.
The engine wont start at all with the cast-in numbers.
It will start and idle poorly with the hayes numbers, but it wont rev up at all. Throttle change does nothing. another interesting condition is that unplugging sensors (IAS, TPS, CamPS) does nothing at all.
I am puzzled. what is the correct sequence? why does the engine running seem to be running sensorless. BTW it is a 1990 xj with an 88 block
