i have a 1993 loyale that ive been working on for little over a month and a half . the other day i replaced the fuel pump because it was leaking pretty bad but now the car will only run when you pour gas down the throttle body . im kinda thinking the fuel pressure regulator went out as its getting pressured gas up to the regulator

1--Did it start before you replaced the pump?

 

2--Is the wire connector thingie coming off the fuel injector plugged into its mate in the wiring harness with a good, clean connection? (Not gummed up)

 

If it's not either of those simple things, and it starts with starter fluid, then we'll cross them off and move on to more involved stuff.

yes it ran good but the pump was leaking really bad

i will check the wiring agin but it seem to be hooked up right but it dosnt seem to be getting fuel now but is getting fuel up to the regulator

Are you working on a SPFI or MPFI engine?

 

You can pull the line from the output of the fuel filter where it connects to the intake, put the end of it into a container and hit the key. If the pump is working properly you should have flow from it while the pump operates. If there is no flow then you know you have an issue with your pump. If you have flow then id check the fuel pressure.

Grammar

its single point im thinking the problem is in the pressure regulator as im getting pretty good pressue up to that point

im thinking its the fuel pressure regulator as i know its getting fuel up to the regulator and it will run when you pour gas in the throttle body

Found that they fuel lines got mixed up on the throttle body

Thanks for all the help
