Oil pressure fine when engine cool or not at idle.when at idle and engine warm pressure drops to zero,chevy 2001 express 1500 van

Since the oil pressure reads fine when cool or not at idle, the problem is probably the oil pressure sending unit. The easiest way to check is by replacing it, and it is fortunately not an expensive part.
Let's hope that is the correct fix.....
Think about how you noticed the problem....was it a gradual thing, with the gauge reading lower and lower until it was at zero, or one day it suddenly just happened? If it was a sudden thing, the sending unit is the probable cause. If it was gradual, there are several other possibilities, one being the oil pump itself. When an engine warms up, the oil thins, and a worn oil pump cannot deliver as much pressure. This can be fixed for a relatively low cost by a do-it-yourselfer in an afternoon or so, by replacing the oil pump. This requires removing the oil pan, and in some (not all) cases the engine must be unbolted and jacked up enough to allow the oil pan to be removed. A worst case scenario would be if the loss of oil pressure at idle is caused by worn main engine bearings. This would require major engine service.
If you really do not want to put any money into your van and just need it to last a little while longer, if the problem turns out to be main bearings, you can alternatively add an oil thickening agent like "STP" or "Motor Honey" to the oil and thicken it up enough to build up some extra pressure. Please be advised that this is not a "fix", but it will get you a few more miles out of your van in a pinch....eventually the bearings will fail. This will also help a worn oil pump build pressure, but it depends on how worn it is. This about covers "best case", "middle case" and "worst case" scenarios. There are some in-betweens, but unless you have noticed strange engine noises you do not have to worry about them as much.
Stay positive and go for the oil pressure sending unit first!

Has spark has fuel pressure but wont start

Does it have injector pulse to deliver fuel to the cylinders? You can check to see if the injectors are getting power by probing the red wire to the injectors, with the key on it should be battery + voltage, a common cause of this kind of problem is the ignition starter switch on the top lower part of the steering column. You can also buy a small tool that plugs into the injector connector called a "NOID", (about $5) it flashes when the engine is cranked if the injectors are been pulsed to deliver fuel.

My 2005 Chryler Town & County 93000 mile is having transmission issues. The trans downshifts erratically-no codes-45-55 miles per hour. my mechanic can't seem to fix it. Thanks for your help.

Try replacing the throttle position sensor. They can get 'noisy' electrically which confuses the computer, yet doesn't set a code for the defect. This sensor is supposed to deliver a smooth transition from near zero DC volts to near +5 volts as the throttle position is increased. Hope this helps!

What is the ideal operating fuel pressure for an 89 Corvette w/ LT-1 TPI

The 5.0L injector is sized to deliver approximately 4.05 milligrams of fuel with a 2.5 millisecond pulse or 18.13 lbs per hr at approximately 36 PSI. The 5.7L injector is sized to deliver approximately 4.83 milligrams of fuel with a 2.5 millisecond pulse or 23.92 lbs per hr at approximately 43.5 PSI. This information is typical for all manufacturers and flow rates will vary slightly even between identicle injectors.
Good luck and hope this helps.

You may have a faulty check valve in the fuel pump which should hold a static pressure of at least 1 psi to the injector.Excessive cranking can be caused by this due to the fact the fuel pressure needs to build back up in order for the injector to deliver fuel.A proper diagnostic step would be installing fuel pressure gauge and verifying any static pressure held after the engine has turned off.If the fuel pressure gauge drops immediatley to zero,this might be your source of the problem.Another source could be improper temp sensor output or crank/cam sensors therefore an E/C parameter check with a scanner could prove usefull.
