The only "fail safe" it has is that the idiot cluster will light up for low oil and the buzzer will go off. The same buzzer for redline/low coolant.

A car with low compression will still "work" very well, it just won't pull as hard, but you'd probably never notice that. Low compression really begins to cause issues with things like hot start and idle.

so if my attachments work you will see from the fsm what im talking about....remember NA

1. on position no voltage at pump wiring harness (R0-3)...in yellow
note: i know two top supply voltage--- bottom two fuel level sensor

2. From FSM section 4A-74 **NA** when checking voltage at fuel pump relay...
a. ON position checked out
b. ig sw Starting no voltage from Fc which is "fuel pump switch"
c. failed to check (no time) with measuring plate open

until this point i was going to as you know rewire the fuel pump i have the materials and im in a holding pattern suggestions guys based on 1-2 info above
