1996 4.3 Chevy vortec it won't start unless I put fuel down intake I have 58 lbs of pressure at the fuel rail It starts again after it has started but not after it sits for a couple of hou?

Fuel pressure should be 60 to 66 PSI. If you are sure that you have 58 LBS Then the engine won't start. And it will do what you are saying it's doing.
It has got to have 60 LBS to start on it's own. NEED to replace fuel pump and filter.
You can check it this way if you want. After it has set for a few hours are over night.
when you go to start it next time. Just turn the key on, wait 3 seconds then turn it off. wait 10 seconds, then turn it back on again for 3 seconds. then back off for 10 seconds. repeat same steps 2 more times. After the last time turn key off wait 20 seconds, then see if engine will start on it's own. Either way Im sure you need a pump.

2002 dodge ram 1500 4.7L Cranks and starts after 4-6 secs When warmed it starts fine Check engine sometimes reads cyl 6 misfire Plugs replaced numerous times coil packs fine too Fuel pressure fine?
Sometime the fuel pressure leaks down went he engine is turned off for a couple hours or more. If that happens the engine may be difficult to start later. Try turning on the ignition switch for a couple seconds allowing the fuel pump to build a little pressure, THEN crank the engine. See if it makes any difference.
Why is valve overlap important?
Having the exhaust valve still open when the intake starts to open uses the exhaust "pull" out the exhaust port to help start the intake charge entering the chamber -- before the piston has started down and has generated it's own vacuum. Also, leaving the valves open longer (duration) increased the density of the intake charge and allowed the headers to better scavenge the exhaust gasses out.
98 mercury mystique that when started goes above 2000 rpm fine then drops off and dies Have replaced the MAF sensor no luck?
Connect a fuel pressure gauge to the injector fuel rail. Watch the fuel pressure when you start it. If the pressure drops off as the engine starts running bad, it's probably either the fuel pump or fuel filter.
On a 1989 S10 Blazer where does the 4x4 vacuum hose start and end?
IT starts @ the intake manifold & ends on the front axle.
When did science started?
When the Arab Muslims started it back in the days. It was the Dark Ages for America and Europe, but it was the Golden Ages for the Muslim Arabs that invented and started all the science that we have today. Then the Muslims were kicked out of Spain and all the science was left for the Romans. -MUSLIMS!
You have pressure in the fuel lines and it doesn't start you put fuel in the intake manifold and it starts Bad fuel pump?
If you put fuel into the intake and it starts and keeps running, replace the engine coolant sensor. If you put fuel into the intake and it starts but stalls it probably is a bad fuel pump or pressure regulator. Do a fuel pressure test. Need to know what model, year and engine you have to help you any more.
Why an intake pressure boost in a two-stroke engine is a must?
After the exhaust blowdown is nearly complete, the intake slot starts to uncover. At this point an intake pressure boost is needed to increase the pressure at which the air enters the cylinder, to push the remaining exhaust gases and fill the cylinder with combusted air-fuel mixture.
Why does my 92 Camero runs good for a couple blocks then dies. Sets a couple min then starts and idles give it gas and it dies?
I would replace the fuel filter and check fuel pressure.
Why does my 92 camero runs good for a couple blocks then dies. sets a couple min then starts and idles give it gas and it dies hit starter and it starts easy but dies when you give it gas?
Inadequate fuel pressue probably. Check fuel pressure with proper gauge.
What is the reading of oil pressure gauge before engine starts?
Oil pressure shouldn't register at all until the engine starts and builds up pressure.
How do you get an aquarium overflow started?
I'm assuming you mean an overflow filtration system? If so, then just take a cup and pour water into the filter housing until it starts to overflow. It might take a couple of cup fulls before it starts working.
