I know this is not a Ford question but there is some great techs here. Anyway here it goes. I have a 92 s10 as a beater truck and lately it's been running rough. My fuel pump went out 2 months ago and change it and ran fine. I recently fixed a leak in the fuel line and also change the Fuel injectors. After I changed the fuel injectors the thing has not ran right. I have to put gas in the throttle body for it to crank and then it runs but runs rough. I know that if you have to put gas in the TB then it is usually the fuel pump but because i just change it and it runs okay after it cranks i ruled out the fuel pump. There is no gas spraying out of the injectors when i try to crank it but after it cranks gas is spraying. I have no idea. Seems like there might not be enough pressure or something to push the gas out of the injectors when I try to start it. Like I said once it is started gas sprays fine. ANy ideas?? Any help is much appreciated.

 

Fuel Filter?

Pressure regulator?

 

Well I unhooked the fuel line and there is no fuel coming so I guess it is the fuel pump. When I turn the key I dont here it kick on like Chevy's normally do so I guess we will see 2 morrow.

 

could be fuel pump, maybe fuel filter too.

 

Check your oil pressure sender. Low pressure keeps some chevies from starting. Once it is running there might be enough current through the sender to keep it running.
