Getting my car back together after replacing the fuel pump with a 2-port Bosch 69133 unit from Napa.
Car starts as normal, but when I turn her off she just keeps running. I can remove the key from ignition and she keeps running. And of course, this isn't some sort of overrun condition....actual running. Pull the coil wire and she dies as expected. Other notes, fuel pump is wired to switch power up front (previous owner did this). :dunno: |

your wrap won't cause an operational problem---no its not grounded--has 2 wires to run + and -.
did you also try changing the fuel pump relay? Mine did have this problem also and when changed out the car did run again. Gary so take a voltmeter and pull the 2 wires to the fuel pump and measure the volts when turning on the key---volts??? yes or no.... do you hear the hum when turning on the key? all mine used to do this (FI ones) |

Yes, my pump is running. The pump was wired up front off of switched power by the PO vs. the original fuel pump relay off the relay board in the back. My issue (from the first post) started with car would start but not turn off when putting the key in off position unless I pulled the coil wire. It further degraded to a no-start and noisy pump sound. 1. The noisy pump is likely a crimped fuel line. Also possible that I am very low on gas as I only put in 1.5 gallons and the car is on jack stands in the front. My first step might be to simply put some more gas in or lower it back off the jack stands and try starting again. I suspect it will start again and then I'll be back to the original problem (see #2 below). 2. Assuming I get her to start again, I'm trying to figure out why she won't turn off when I turn off the key. |
