Replying to: esaxton (Jan 18, 2009 5:26 pm) The truth often is that a third party part actually is better than a part from the OEM. I ALWAYS opt for third party part if it is available. A simple reason is that if their part does not work they will be out of business so they must make sure, for most of them, that they work as well or better as OEM part. Car dealer shops can screw up countless times with poor quality parts and people keep coming back, until they are out of business when these people finally realize they need to buy something else, i.e. imports. You did not say anything about the fuel pressure regulator. Was it tested? When you check fuel pressure it can be too low for two reasons. Your pump does not give enough flow/pressure or the pressure regulator is bad. As you very recently changed your pump already why not replace the regulator just to rule it out as a possible problem? I does not cost much. I have not changed it but I would expect the part to cost less than $30. Who diagnosed that you have a fuel pump problem? Dealer shop? If so, make sure they do NOT also replace the fuel pressure regulator to make you a happy customer since it seems dealer shops are the worst ones to rip people off and do unnecessary repairs. Worst case would be that they only replace fuel pressure regulator and don't even touch the pump as they could be aware of the "real" problem and know they can get nearly $1000 from you for a $50 fix. I know I sound pessimistic but this car fixing cheating crap is everywhere and you just need to look for yourself. A fuel pump going out in two years is very rare occasion and just for that reason I would replace that fuel pressure regulator before going after that big job. You can do it yourself. Arrie

Also, I should mention my fuel gauge needle all the way to the right at 3 o'clock ("full" is at 2 o'clock). Your remarks about the fuel pressure regulator sounds like it may be my issue. I've never heard of a fuel pump going out because a car sits (I could be wrong). In the past, I started my old 1966 Mustang that sat in my sisters garage for 13 years!! I have an old Jaguar that I seem to be able to start after it sits for months at a time. Please help! Any advise is welcome.

You had it sit for a year, right? Before doing anything else, based on your post you need to recharge the battery or perhaps even replace it. You obviously have another vehicle so give it a jump start. It could be that there is nothing wrong other than not enough juice in your battery. After you jump it or recharge battery and get good crank and if it still won't start post back and we can think of something else being the problem. Depending on the vehicle they pull various amounts of amperage from the battery even when they just sit. In a year it does not take much and the battery goes empty. Unless, of course, you disconnect battery cable while it is sitting. It also is that when battery is low enough that it still barely cranks the engine it might not have enough voltage for a good spark to fire up the engine. I would try to jump it as I wrote above and think other options after that if needed. Arrie

My wife needed a tow truck today when her 1999 suburban 4wd stalled in traffic. It would simply not start. The gas tank indicated full. When we got it home I checked for spark, good spark. I replaced the fuel filter since I had one laying around, still would not start, but the old filter had a lot of dirt in it. I checked the forums here, and noticed that many suburban and tahoes have faulty gas gauge problems. So I checked the trip meter, which was 562miles. I divided by 13mpg, and it came to around 43gallons. I asked my wife when she filled up last, it was several days ago. I checked our bank records, sure as shootin' it was 4 days ago. She had driven several hundred miles in a Suburban, which "died" on the highway reading absolutely "full". I just put 2 gallons in her, and after a strategic pause, she fired up nicely, purring like a kitten again. I'm not going to mess with the fuel gauge (in the tank), we'll use the trip meter, which is more accurate anyway. When the fuel pump dies on some day years from now, I'll find out what happened to the gauge.
