The pink label syndrome is no fuel pump, but like all old electronics it can have ordinary non-syndromic defects with scattered symptoms. I agree with your plan to find a -951, not because of its different method of cold start enrichment, but because you have no other way to know if the ECU is at fault but to substitute one you know works. Same goes for the AMM. All owners of LH2.4 cars should acquire spares of these two items while one has the luxury of time to shop.

My first approach to real troubleshooting would be to measure the fuel pressure and observe the response to A/F ratio by the switching action of the oxygen sensor. Just the list of new or "different" parts replaced is not enough to base any conclusion.

If you lend someone $20 and never see that person again, it was probably worth it.
