Reposting a now intermittent no start. An oscilloscope showed suspect injector wires as did an ohm meter reading. I replaced the injector wires and it started immediately with AMM disconnected and idled smooth. The next day - no start.
This is an LH2.2 which I've not seen reported as having a 'weak' FI transistor like the LH2.4's. Spark is still strong and fuel pressure and flow are good. I've replaced the rotten alt, temp gauge, starter and oil pressure wires (and the FI connectors and wires). Grounds at intake measure low resistance.
The only other symptom is that with a 'maybe good' 2nd AMM when idling (the rare times it'll start), slow pressure on the gas brings up idle, but a 1-inch push causes a severe hesitation that can result in a stall (starts right back up though).
Very frustrating, mostly intermittent no-start. I could use ideas - this is the rotten wire era, but the FI temp sender reports proper resistance, there is spark, and it has started more than once.
Thanks.
