Engine starts and then dies.

[fixkick]

the suppressor was just taped down , day1. to the harness with black tape (plugged in of course)
it creates the tachometer signal if it falls of all injections end, DTC error 41, the dash tachometer goes dead too.
its really just spark read back from the coil, but is 100% necessary.

if the supressor falls off, (or connections fail for rust,etc) the injectors go dead, and the noid lamp test fails on all 4 injectors.
