I have the same problem and have trouble codes 35 and 36. I found out that there is a computer module that needs replaced as it sits low in a valley and gets hot and seperates. I am reseaching about the a/m fix that installs the new module away from heat.

SOURCE: fuel pump- 2002 GMC Sierra

The fuel sending unit only controls the gas guage not the fuel supply to the vehicle. The pump is twelve volts. If you are not getting twelve volts on the PUMP wires check the fuel pump relay and the key circuit to it. If you have to cycle the key three to four times rapidly to get the vehicle to start check the fuel pump pressure at the regulator for manufacturer specs. An injector stuck open will also cause same problems you are describing.

SOURCE: 95 Camaro Z-28 starts hard

could be alot of things but there are 3 basic principles/requirements for any gasoline engine to start. You need fuel, compression and ignition. Not much you can do about the compression short of having the engine rebuilt so focus on the other two. Fuel includes a good clean air supply (check air filter) and fresh gas (check and replace fuel filter). If the injectors have been already been cleaned, that's about all you can do. Have your spark plugs been replaced? Bad plugs will also cause this problem. The ignition system aslo consists of spark plug wires and other components that may need replacing. If this is beyond your mechanical capability, I'd have a mechanic connect the car to a scope to see if any of these systems are acting up.

Try this. Turn key to the on position, but do not start. Now press accelerator pedal all the way down for say 5 seconds. With pedal still depressed turn key to start position, does engine now start.

Why does my dodge start then die some times it takes 3 or 4 times starting it for it to stay running?

Could very well be a fuel filter clogged. Usually check that first, then check your fuel pump.

Takes a long time for fuel pump to prime before car will crank. sometimes 15+ minutes

Something is definitely wrong with this picture. It should only take 2 or 3 seconds for the pump to make correct pressure. Just turning the key to on turns the pump on to pressurize the system, then pump will shut off, maintaining pressure, until the computer gets an engine cranking signal, at which time pump should come back on, and stay running when engine is running.
The only way to check fuel pressure is with a fuel pressure gauge hooked onto the fuel rail. If you check and pressure is correct and doesn't drop right away, the problem is elsewhere, not in the fuel delivery. You said takes a long time before car will crank-is there a problem with the engine cranking over with key in start? That would be an ignition or starting circuit problem, not having anything to do with the fuel pressure.

2004 gmc sonoma why does it take 2-3 times cranking before it starts and only does it sometimes?

install pressure gauge and watch when key is turned off to see if pressure drops to zero if so bad drain back valve in fuel pump replace it or deal with it or could be cheap aftermarket pump and has hard time building unnecessary pressure to open poppet valves between before fuel injectors

Why does it take a vehicle 3 times to start and then starts normally

you could have a slow leak in your fuel pump to where it leaks back into the tank at there is no fuel present in the morning and has to wait for the fuel pump to bring it from the tank, while you are cranking the engine because it slowly leaked out/back during the night.and since it is 13yrs old...that does not seem unlikely at that age.

My truck takes a very long time to start it turns over a lot and finally starts what would be the first and easiest thing to start with

to start check the whole fuel system for any leaks,and replace the external fuel filter if it hasnt been replaced in a while.Also check to see if the fuel regulator is working correctly.check and see if its your fuel pump by turning the key on and off 3 times each time waiting 3-4 sec. in between and on the last 1 try to start to start it,if it fires rite up then its either your fuel pump getting old or some other part of the fuel system.Also check the crank position sensor,if its dirty and grimy the use some electrical contact cleaner and spray it clean,if its really dirty it will have a hard time starting too.

My 1999 Silverado fuel gauge jumps from 3/4 full to 1/4 full while on but in park. Also it has died a couple times lately while turning a corner. It will start right up if cold but if it is warm sometimes...

Sounds like your fuel pump is going out, I replaced mine at 120,000 miles. The fuel level sending unit is built on the fuel pump, so it will solve your level indication problem as well. The cheapest place I found a fuel pump was, believe it or not, on I searched for the part no., did a search, and found it there at the lowest price.

Changing the fuel pump is not really that hard - would take you and a couple of buddies about 2-3 hours. Email me if you need step by step instructions.

My 1997 chevy tahoe is hard to start, I changed the fuel filter and spark plugs but it still takes a lot of cranking before it will start

the pressure regulator may be leaking. pull he vac line and see if its wet. wet is bad. Also these fuel pump connectors are known to overheat from poor connections. Do a search on gm fuel pump repeat failures and overheating connectors. Also the fuel pump could be leaking down so the line needs to be primed. Try cycling the key about 3 to 5 times before you start it. The pump will prime for 3 seconds each time before shutting off. If this helps the problem is the fuel pump.

Poor engine start

the only thing that comes to mind is, the fuel pump may be weak and not pumping enough fuel when cold. check fuel pump pressure. or replace pump.

Hard to start

Fuel pump is a possible cause but I would check the ignition timing first.
