ok so this 3.0 needed a new fuel pump. there was no fuel psi. so i put the new pump in. i first started it with start fluid then the fuel pump was able to take over from there. but i cant get the car to start with out starter fluid.
the oul is nasty but not low.
the battery has to get jumped each time before starting as well.
also the pump is working. i hear it every time i turn the key to prime it.

ok nothing seams to go agenst your last comment about the battery. i agree complettly but i have a question on this, i did jump the battery with a car (4 banger honda, small battery) and when i cranked the van over it had a very strong crank.
so my question is, even tho it sounds like theres a strong crank, would you still advise that it is still the battery being worn down?
i mean its gonna need changed anyways (its so dead u need to jump it to start anyways.) but im just trying to find a final solution so i can better help this lady out.
Was it working(starting) fine before the FP went/replacement? Sound like a good idle once you get it started with fluid after a bit? If she’s got to get a new one anyhow, why not try once with new one? Or swap out with a known good one with as high or higher CCA rating? Then I might go on from there. I don’t think you’re going to be able to solve it for her with one final trip.
If you suspect a problem with the battery test it, it’s that simple. Don’t forget about the connections however as those are just as important.
My friends van did something very similar. The cat would only start some times and when it didn’t we would have to disconnect the battery for a few hours to reset it, then it would run fine. It would happen about every thirty cycles of the key. We figured it out to be a loose soldering connection on the back of the instrument pannel. We fixed it by taking the dash apart and re soldering the connnection. Tue cat has run fine ever since.
If the battery is dead and needs to be jumped.
The proper voltages to run the car will not be
there.The alternator can not do it alone. I guess
we could say the battery and alternator are a marriage.
if one is not happy the other is not happy.Address the battery
and charging system.[quote=”bwebb” post=36517]Ya there is plently of fuel psi. and the car runs fine, just when i start it i need to use starter fluid to get it going.
keeping in mind that the battary sucks [and every time i go to start it the car needs jumped] could this battery be so dead that it wont creat enugh power for the spark plugs to ignite gas but it will ignite the starter fluid. then the altinators power takes over and is suficent enugh to power the spark plugs more so they can now ignite gas as well. dose this sound something that could happen at all? ive only been a mechanic for a year now so im still learning these things[/quote]
Considering this doesn’t have a schraeder valve and takes a specialized adapter to check fuel pressure, how did you verify the proper fuel pressure? What was the exact PSI? Obviously something isn’t so good if you’re ethering the thing to death. If you know the battery is junk, why hasn’t it been changed yet? It will cause you trouble in and of itself along with straining the hell out of your alternator.

Did you clean the tank thoroughly when you replaced the fuel pump??? and fill it at least half full???? A couple gallons is not enough to fill the fuel pump module!
[quote=”bwebb” post=36495]there is fuel psi.
there is sufficent fuel for the engine.
the battery is crap
the alternator is good.[/quote]What is the PSI at the fuel rail? What is spec PSI?
How many gallons is “sufficent” fuel for the engine?
Why use a crap battery when FP needs good voltage and current to perform properly???
Why risk alternator trying to keep a “crap” battery charged
How do you know battery is “crap” Have you had it load tested? What were the load test results??
What voltage did it go to when tested?? How many amp draw for test???
For a proper evaluation these things need to be known since we cannot be there to do the testing you need to provide them for us.
