sorry bout that second line i ment to say "im still stuck on the fuel pump because it didnt pump" ect

how would i check the fuel pump relays? where are they located i'm not to familer with z's because didnt pump when i checked it still on the car( i had some one turn it over and i was underneath looking at the unhooked fuel line going from pump to injectons) however after i took it off and hooked it up to power it ran.it didnt pump all that good however. i'm use to water impeller pumps in outboards with the rubber impeller that always goes bad if there is somthing clogged in the pick up line is the fuel pump anything like that. something rubber that can be burnt up so it wouldnt pump that good. thats why im stuck on the fuel pump i want to get one problem solved at a time. would a plain electric fuel pump with the right hose fittings work on this injecton i have priced them out at a local car parts store and there around 40 dollors or should i looked for a used pump off a z and how much would that run.

how much is that fuel pump suppose to pump. could i get away with replacing the metal fuel lines(there pretty rusty) with some high pressure rubber lines. ok i've been looking at the underbody in front or unibody it looks awful rusted would it be worth it to repair or to part out and sell the parts. i would like to keep the car but i looks like alot of work how much work did you guys have to put in your cars to make them look nice? and are 280z's fast enough for the 1/4 mile thanks ( sorry for misunderstanding your writing)

well i checked and replaced fuel filters and some bad fuel line i dont think its getting gas because i put some gas in a cyl. and it fires but wont stay running. nothing happened unnormally when it stopped running. all i did was shut it off and tried to start it after about 1 hour i dumped the gas by taking out the drain plug in the gas tank. it didnt look dirty just really old and varnishy. i checked the fuel pump and it dosent pump very good so im looking at replacing it with just a in-line plastic electric fuel pump. unless you have any better ideas. how do you clean the injectors? i can clean a carb in about 20 mins but injectors im stumped with. hey beandip i work at a local marina so just remmber im not totally dumb about troubleshooting engines but this early of injectors have me wondering

I unhooked the filters and changed them but no diffrence i just got done taking off the fuel pump and i hooked it up to a trickle charger to see if it would pump and it did but i think it might be in the wiring because when i took it off i checked if it was pumping gas and it wasent i couldnt hear if the pump was running over the engine turning so i'll put the pump back on and see if that does the trick how would i go about checking timing? i have also thought about that route. thanks!!

Hey ya'll i just bought a 78 280z with a 6 cyl. overhead cam. i was able to drive it home but when i got it there it won't start. i have no idea why all of a sudden. i dumped the old fuel and put about 4 gallon in the tank but still no start any ideas??? maybe possible fuel pump? its bugging me really bad (anybody know how big of gas tank would be in that)
