...the fuel pumps. Only after the engine starts. It`s a safety feature. To operate the fuel pumps, uncover the relays behind the coolant expansion tank. Remove the fuel pump relay (the innermost one). Bridge terminals 30 and 87b (you should use a 15 amp fuse for safety). The fuel pumps should run.

Just installed four new fuel injectors this weekend and car wouldn't start after the job was completed. This doesn't completely surprise me, I figured they would take some time to re-prime so I left the key in #1 (accessories) position for a while to let the fuel pump fill them up. I tried cranking a few times but it never started, I repeated this series a few more times but nothing. I don't hear the fuel pump humming while the key's at #1 which leads me to believe thats the problem. Can I just pull a fuel line somewhere, turn the key and see if it pumps fuel everywhere or is a multimeter needed (procedure?, please)? I'm sure it's a fuel delivery problem because afterall I replaced injectors and the cap and rotor are brand new. Please help, thanks!
