92 corolla 4 cyl auto. Just quit running and won't restart. Has spark, about 45? Degrees advanced. Not the 8 it is supposed to be. Getting the EFI signal to the injectors. Fuel pump runs then shuts off. Had 2-4 and 1-2 trouble codes. The IAT sensor checked good and N2 signal is present at the test location. Replaced computer with used one. The codes cleared and still won't start. Any thoughts

Are the sparks bright blue and constant while cranking?
What are the cylinder compression pressures?
Check the timing belt for jumped timing if ignition timing is advanved by too much.
Does using starting fluid changes anything?

Spark is white and good.
No gauge but spins w/out plugs and surges with plugs in.
Not checked yet.
Won't run on starting fluid.

The diagrams shows the timing marks.

Since you have not removed the lower cover and pulley, turn the crankshaft till it is at TDC whereby the timing mark on pulley aligns with the 0 (TDC) moark on the pulley cover.

If the valve overlap is at cyliner 4, check the cambelt timing as shown in diagram. There is a small hole which aligns with a mark on the cylinder head behind it, not easy to see.

It seldom occurs but would if the tension is loose.

In your other post you mentioned no sparks at the moment. Seems it is getting complicated.
