New part came in extremely quickly, was able to pick it up after work. Swapped out without issue and it'* running great. Better than it had been for quite a few months, actually.

Thanks for the help, cheers.

Adding to this old post:
1990 Bonne LE 3.8L Vin "C" 89K miles...

What could it mean if, when the MAF is pulled, the engine cranks well but won't start at all (and has no codes stored)???

Is the ECM not throwing codes, and also not running on the predetermined/default values??? (So instead of the MAF being bad it'* actually the ECM?)

This is a great opportunity to learn but very frustrating...
Much thanks!

It means you check for fuel pressure, spark, and injector pulse.....

Shouldn't jump on a 2 year old post......start your own......
