i messed your post on injector noid oddities. (fully)
stuck on?
is that before caps or after caps, ???
if the caps are bad the regulators (VRM) go nuts, and if those go bad (5vdc reg) the CPU goes nuts and with that nuts so be injections and more.
GIGO in computer land means garbage in gets you garbage out and power is first.
The ECU processor inside (CPU) must have clean power 5vdc from its regulator inside ECU or the CPU will fail. and do anything bad really.
in the world of electronics for sure this, power is first, clean stable power, and is 5vdc inside there.
there are 2 regulators inside one for all digital electronics and one to run only sensors outside ECU. ECU pin B6, 5vdc., gray/red top of TPS. is here.
Bad caps cause the ECU to reboot , endlessly cranking, and the battery is dropping low, even to 10volts low, and this will cause noise that if reaches the CPU inside
it crashes and self reboots, and this can even fail in a loop cranked, even so bad you hear lots of relays in the car and VSV all clicking like mad.
that is dead CAPS HORROR prime, vast folks seen this now, in any DEGREE of better to worse.
the battery must be good and charged, this starter only uses 100amps so a 500amp/hr battery has no problem pushing 100 amps.
that means battery voltage stays above 11vdc, if yes the ECU works and the caps clean up the noise and all things happy feet, this ECU has no LDO VRM regulators inside, low drop out regs here, they are not near this quality.(legacy stuff)
recap it and test all outputs for shorts sure.
