Have a jd 7775 skidsteer that won't start on its own without the help of either

SOURCE: car will not start

there is no such reset switch located in the car. First turn your key on and listen for the fuel pump to pressurize the lines. Then check to see if the fuel is leaking from the  filter. If it is you may have got the connection wrong. If thats the case your engine is not getting the proper fuel pressure to run. Hence its sucking air. If that does not work you might have a bad fuel pressure regulator sensor that is bad. Its located by the TBI. Reference a Haynes manual for replacement.
also if you did not fill the new filter with fuel then you have air in you system and engine will not run. so try taking it off and filling it with fuel and then replace it.
--------------------------------------
turning ignition on removes air from fuel lines and primes the fuel system. filling fuel filter with fuel is irrelevent, as lines need to be clear of fuel upon installation. leave ignition on after installation for roughly 30 seconds-one minute. this will prime the fuel lines and remove air and most water from the system. if problem continues, fuel injectors. this is a common problem in 90-92 camaros. if cannot start car, you'll need to replace every injector, as it's not cost-effective to diagnose every injector. roughly 300 dollars in quality parts, roughly 4 man hours of labor. if rough start that requires push on accelerator (try this), run the car with fuel injector cleaner. this should salvage you injectors. if this helps proformance, starting, then for the next 3-4 full tanks of gas, add stp injection cleaner for every tank of gas. be careful, as this does not restore your injectors, but it helps clear away deposits which are common in multi port injectors.

SOURCE: no voltage going to new fuel pump

The GRAY wire i believe going to the fuel pump is the hot wire it should come on for 2 seconds with just the key in the on position this is were you should check voltage for 2 seconds then it will go away until you crank the truck.Your oil sending unit is behind your distributor that could be the cause .

Hi,
It sounds like your engine is firing out of time.
Here is a link to the manual for your engine. It does contain some good info and I hope it will help you to solve this problem.

Best of luck!

SOURCE: fuel pump relay switch not working/ fuel pump emergency switch?

If the pump is making sound, then the relay must be ok.
It could still be weak, but you could tell with a pressure gauge.
(Harbor Freight sells a gauge kit cheap.)

But make sure the ignition is working first, by spraying in some starting fluid.
It is even sputters, then you know the ignition is ok.
If not, then check all the fuel injection connections.
The the temperature sensor and mass air sensor.
Use an ohmmeter, and check resistance against the norm.

ok could be a few things.

Have you changed the inline fuel filter? these usually have paper filter elements and after a while can be clogged with moisture which blocks fuel flow. The fuel pump will still have good pressure but the fuel rail will lack the flow required and you may burn out an injector as its running too lean. Secondly, the MAF sensor, could be dirty, clean it with electrical cleaner.

I think its more likeylt the fuel filter blocked. Try and bypass it if possible, reset the ECU and try agiain
