Sorry to bother with Off Topic but....
My dads Suburban quits at times because of lack of fuel and won't start for quite some time after if we are lucky.
My nephew was boosting his truck and my niece says that the volt meter was down in the red zone quite a bit a week ago.
We replaced the fuel pump and relay and it is the same thing.
I have to bypass the pump relay to get the pump going when it is in this condition.
The injectors are not spraying a good full spray that I thought I would see when the engine is off and ignition is just turned on.
If I have to bypass the pump relay to get it to work, then I think the problem is leading to the computer.
I think the roll over inertia switch is between the computer and the pump relay but I don't know where to find it to test it.
Don't get me wrong. I am only trying to bypass these components in order to find the problem and would not leave them bypassed. I would do the proper repair after I find the bad component. Even with the pump relay bypassed so the pump runs, It still will quit when slowing down for a corner and will not start again for quite some time. Fuel poured in the engine helps to get it going. I think the common denominators are:
1- signal to the fuel pump relay sometimes
2-injector signal is not proper for demand. I don't have a fuel injection pressure tester but I will get one if I have to. Does any body know where I can find the inertia switch (come to think of it, I don't think that is the problem)
Does any body have any ideas.
I don't have another computer to try as a test
Just scraped the old 88 Suburban 2 months ago. Thanks in advance

Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
