Check your main relay, it runs power to your fuel pump

what's the main relay? and how do you check? the fuel pump is pupping fine, took off tha bolt on the fuel rail and it sprayed fuel out.

You sure it wasn't your injectors that were bad?

Are you getting spark? Fuel? neither? Check here before you spend anymore money and troubleshoot the problem.

nope main relay is good.. the cel goes off after liek a second.

i wonder if its possilbe that i installed the fuel pump wrong.. because yesterday b4 i installed it i tried to crank it to see if my old fuel pump was still good and it ALMOST started.. the rpms rised but didnt fully start.

and now i changed the fuel pump and the engine cranks but no turnover . i can hear the fuel pump working though, its like hissing when i put it on the on position xD.

ima check the injectors and check for spark.. anyone close to 91765 wanan come down and help a noob out xD

We are all having the same problems at the same time
Ill let you know how and if I fix my similar situation. If you can get the service manual there is a very detailed section on the fuel injectors and ECU trouble shooting. Here is a more detailed write up for the main relay other than just hearing a click... Also has info on ignition problems and ECU problems!
