Hello all, I created an account just for the sake of getting help with this tricky problem…
I have a '95 Chevy Caprice Classic 4.3L Sedan, and it cranks but does not start.
This started happening after about a year of the car just sitting in the driveway. Before she sat for that year, she ran just fine.
I am under the impression that the problem is the fuel pump, it is NOT running when the ignition key is turned to the “on” position,
this is very confusing because a volt meter placed on the connectors going directly into the pump motor shows 12+ Volts when the key is turned, for about 2 seconds, as it should, however the pump motor does not run. Also, I have already replaced the pump relay AND the entire pump assembly (though the pump I used as a replacement was also pulled from a junkyard vehicle).
The MOST confusing part is, when either of the fuel pump motors that I have are plugged directly into the car battery, they run just fine. So I have no idea what the problem could be at this point!
Please help! Thank you for reading.
