QUESTION: still get ignition, car turns over but will not not run.
I would say I am losing fuel, does not appear to be getting to injectors. I am not a mechanic so my knowledge is limited . fuel filter is in the line just under the driver side door I have it checked 2 times and emptied it of gas and then checked again to make sure there is a flow to the filter.
ANSWER: Remove one of the 2 wire fuel injector harnesses from the injector.

Check for battery voltage on ONE terminal. If you have battery voltage on ONE terminal then proceed.

Take test light and put the test light alligator clip one one of the 2 wires and the tip of the test light on the other wire in the same connector.

Crank the car and see if the test light flashes ON and OFF.

Repeat with other injector wires.

If no test light flashing ON and OFF, replace computer.


NOTE: when you are cranking the engine to try and start it, Can you see fuel spraying from the injectors ?.

QUESTION: Sorry for delay....checked all of the above , no luck I have also found that the diagnostic codes do not show  when called on the digital screen , could this be further proof of ECM FAILURE ???? CHECKED GAS LINE GOING INTO INJECTOR BODY AND THERE IS GAS IN LINE!!!!

Answer
Take one of the injector wires OFF the injector.

Turn ignition ON.

One terminal should have battery voltage. DOES IT ?

If it DOES, Put the test light in place of the injector and crank the engine and see if the test light flashes ON and OFF. DOES IT ?. If NOT, Replace the ECM computer.

To enter diagnostics:

1. Ignition ON. Engine OFFF.

2. Simultaneously push and hold the OFF and WARMER buttons for 3 seconds and release them.

3. Diagnostic codes should appear and then stop displaying.

4. Do you get any codes ?
