It sounds like the fuel pump relay ,they have a long list of faults ,if you still have the old relay take the top off it and with a small soldering iorn dab it on all the solder joint,s and put a dab off fresh solder on them ,just be careful not to l et them run together.
I dont believe it to be your computer now a relay sounds like stuck open these are simple to diy yourself under hood theres a fuse box relay pannel find the relay marked fuel pump now check other relays to see if the numbers match switch relays by pulling out basically trading spots if problem goes away just need relay replacement
Also have your car taken in for a free inspection could be a bad fuel pump or alternator getting ready to pass on check always basic things first spark ignition fuel and exhaust if runs you know one of these are failing do to maintenance
vehicle wont crank? you have other issues. if it cranks but wont start then we may be looking at a fuel pump/relay/pressure regulator issue. the easiest way to test this is to simply buy a new relay( they are usually pretty cheap) or find a simular relay in your junction box or elsewhere, such as an a/c relay and switch it out typically if it fits it will suffice. how ever when they go out they usually go out completely. i would start by testing your fuel filter. remove it and try to blow throw it. if its good you should easily be able to pass air through it. if you cant or it seems restricted then replace it. if the studdering sounds continue after checking and replacing the filter and relay (both cheap parts, i dont know the year make and model but you should be able to replace both for around 30-40bucks) then its definitely your fuel pump and they typicaly run upwards of 100-400 bucks. and are a pain in the **** to replace as they are in the tank. just a side not some vehicle dont have and in line fuel filter, they have a "sock" on the pick up in the tank (jeep cherokee for example) other cars are well known for thier pumps going out around a certain mileage. let me know the year make and model and i can help walk you through the problem.
Are you getting battery power and ground at the fuel pump connector? (This should have been checked BEFORE replacing the pump)
Other things to check:
1. Fuel Pump relay in the Engine Compartment Fuse Block
2. The relay is powered (Secondary -or- "fuel pump side") by Fuse 0 in the Engine Compartment Fuse Block.
3. The relay Primary -or- "control" side is powered by Pin 37 RED wire at the PCM
4. The relay Primary control (or ground circuit) is operated by Pin 22 LIGHT BLUE/ORANGE wire at the PCM
5. The Inertia Fuel Shut-off Switch located between the fuel pump relay and the fuel pump may need to be reset. The switch is located behind the right kick panel. The DARK GREEN/YELLOW wire at the switch is the feed from the fuel pump relay. The other wire goes to the fuel pump. Some units have the DARK GREEN/YELLOW wire going in and the wire going out can also be DARK GREEN/YELLOW, or PINK, or ORANGE - the wiring diagram for your vehicle does not specify the color of the wire that actually goes to the fuel pump itself.)
6. If none of the above produce any results, make sure that your ground wire at the fuel pump has good continuity to ground. It usually screws to the left frame rail near the fuel tank.
Any of these components (including the PCM) or their connecting wires could be the cause of your problem.
HELLO,THE 3.8 SUPERCHARGED (VIN 1 MOTOR) IS UNIQUE IN THAT THERE IS A FUEL PUMP RESISTOR THAT IS NOT CONTAINED IN AND REPAIR MANUAL (I WORK AT A GM DEALER SHIP AND WAS HARD PRESWSED TO FIND IT IN THE BONNEVILLE SVC MANUAL.THE FUEL PUMP RESISTOR IS IN THE PASSENGERS SIDE FRONT CORNED (KIND OF UNDER THE BUMPER AREA) ITS SILVER IN COLOR AND IS ONLY ON THE SUPERCHARGED MODELS.GOOD LUCK RAY.
