Hi,

that would make sense... once I get it some gas it runs fine.

I'll check connections first... a free fix is always good.

but is it difficult to replace the crank sensor? if it's not sending the
signal to turn on the fuel pump it'll do exactly what mine's doing...
then when it finally flips on it runs fine.

the O2 sensor in front was a breeze.
