Sunday April 8

I turned the key, car started right up (after not wanting to start at all yesterday), ran beutifully at around 1000-1100 RPM, then around 30 seconds later, just stut off - no stumbling at all - opposite to the other times were it usually stumbling and slowly idled low.

Now no longer fires up. For the heck of it I tested the crank sensor again through OBD and the code shows that the signal is received, so not sensor related nor ground to ICU.

I pulled the return line from the fpr and no fuel comes out when I crank.

I replaced the fuel pump relay with another one (tested good, both are resoldered) and still no start. I cannot test spark at the moment, I am alone on this.

I checked the black wire coming from ignition amplifier behind coil to where the spade connects behind the left headlight, its super clean. I bypassed the grounds from engine to chassis and chassis to battery, still does not start.


Any ideas? Could it be fuel pump?

Thanks,
Greg
