Question about 2004 Oldsmobile Alero

1 Answer

I am trying to fix an 04 alero. it cranks but does not start. i thought it was a fuel pump or presure regulator but it has 53lbs of presure at start up and 57lbs at running. the only way it will start is if i put a splash of gas in the intake then it will run really good and have lots of power. i have no idea what it is. call if you have a idea 715-218-4534 my name is chris

    i am thinking it is the crank or cam sencer. the gas was just put in the car and it will start and run on just a one squart or starting fluid. it dont take alot of starting fluid. this is why i am beating my head against the wll with this car. the car has a plastic tank and is spotless i took it out and looked at it. the car i drove it home and in the morning it didn't start. that is weaird.

This sounds like it may be as simple as cleaning the water or gunk out of the gas tank which is what I always do 1st because it's easy and inexpensive.
Gas that has sat for an extended period will lose igniting power and will not fire easily that's why we have to add winterize to our lawn mowers' gas when storing for the winter.
Fuel Systems always gets contaminated with carbon buildup, gunk, grime, water and/or bottom junk like rust and this will cause the problems your having!
Fill the tank with High Test, Add some dry gas and a good fuel system cleaner or 2 or 3 and this should dissolve all the gunk and clean the injectors and fuel system!
Use a can or two of starter fluid to get it going and idling on its' own!
Read & follow the cans' instructions carefully.
If this cures the problem never let your gas tank get below 1/4 and especially never run it to empty as this is when the gunk and/or water will enter the system!

2003 olds alero crank no start, thought it was passlock. by passed this, it almost starts with either. cycle the key and pump works but no pressure after that.


Make sure you're getting power to the fuel pump after start up. GM cars provide power to the electric fuel pump via the starting circuit when cranking and switch to alternator/battery power via the fuse block and 12v relay with ignition on in run position. Check your fuse block (bad fuse; power not getting to part of fuse block) and fuel pump relay. Could also be plugged fuel filter, bad pump or ?. but not likely because you get fuel while cranking. Check for error codes in the engine control computer (GM OBDII) as well but that probably won't show anything. Good luck and good hunting. I had a similar problem with a Chev Astro. Turned out to be power not getting to one bank of the fuse block because of a burned junction terminal buried behind the battery under the hood. Get out the multimeter and start looking for failed electrical components or broken wires.

Fuel presure @ idle is 70, reg connected with new regulator


fuel pressure is too high. Should be 40 to 45.
You intermittant no start may be a bad crank sensor or hall effect sensor.

Alero will crank awhile before it finally starts w/ more details


May have small fuel leak or fuel pump sending unit leak down. Or fuel pump psi low.

After 30 minutes try this turn key on. do not try to start wait 10 seconds turn key off then on again 10 seconds then try & start if it starts right away fuel system is losing PSI either back through the fuel pump or a leak in line. If you can find no leaks would suggest replace fuel pump & assembly.
Another possible but rare fuel injectors may be leaking fuel over time & dropping PSI needed for start up.

Fuel presure dodge diesel ?


all i can tell you is that as long as you dont go below 4 psi you should not starve injection pump, this is a minimum psi though., 10-13 psi is average on my 2002 at service port.
