stranded again what gives? ideas

Have you checked your fuel pump wiring?

You can check your compression with a standard compression tester. Here is an example, you can search youtube for other examples.

there you go lunchbox....got the stethoscope out no sounds up front when inspecting the fuel pump in back again nothing....so yes a fuel issue definatly changed the filter anyway...

it got dark on me didnt have time to get the multimeter out will break it out tomorrow

btw it did the same thing...cranked right up but died out because it wasnt warm due to bad idle....it did this two more times before it ran and just died out and yeah the final time as if it abruptly lost fuel, trying to start from this point yielded the same results as before

the car was low on oil theres no fail safe is there cutting out out power to the pump?

I do not believe that there is a fail-safe based on the oil level.

The pick up screen in the tank could be getting clogged up, so you might check that while you're checking the internal wiring to the pump.

I would recommend running new wires to your fuel pump, and definately make sure that you have a good ground for your fuel pump. There are some pretty good write-ups about how to do it; however, I'm fairly sure it's pretty straight forward as you're just replacing old wire with new, and securing a better ground.

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.

1. all good to know. will check into i have a friend in mind with tool

2. still have the rewire (fuel Pump) to do im reading up on the for NA. also decided to change the fuel hoses/clamps didnt like the condition

atsronnyats · 09-21-2010, 01:05 AM

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
