WheaT_BeeR_MaN Posted May 23, 2009 Share Posted May 23, 2009 so i bought a new universal elctrical fuel pump. i test the wire to find out which is hot. what i got was no volts till we let off the cranking then my light lit up. now id run wires to it but i know its not suposed to be on until you r cranking. so anyways im kinda lost on what i should be looking for or to bypass. it doesnt make sence, oh and the fuse is good.

WheaT_BeeR_MaN Posted May 24, 2009 Author Share Posted May 24, 2009 also something else kinda wierd is my charge fuse is real real dim with my test light. it looks just like the fuel pump wire when i test it. not sure if theyre related. i read in another thread could be the VR? is that the voltage regulater?

SkankinPickle Posted May 24, 2009 Share Posted May 24, 2009 since'82 the voltage reg. has been built into the alternator so it's all one unit. Fuel Pump relay good? (it's right above hood release handle inside the car) I'm sure you already gave your old pump 12v and it didn't make any sound right?

GeneralDisorder Posted May 24, 2009 Share Posted May 24, 2009 If you have no power to the pump while cranking but you do when you stop cranking then I would suspect the fuel pump control unit above the hood release handle on the driver's kick panel. It's more than a relay. GD Quote Link to comment Share on other sites More sharing options...
WheaT_BeeR_MaN Posted May 25, 2009 Author Share Posted May 25, 2009 ya i checked the old one. ive been reading in threads for alot of hours and it seems like the box on the hood release should be whats wrong but all the wires are black. theres about 8 of them and about half of them are hot. i bought a multi meter today but i been hanging with the family. so probably tomorrow ill check voltage. do u know which wire in the plug is the fuel pump er tach? i also was going to try to hook up a hot switch just to get the car running. what do u think? the car sat for 10 years and i got it started with starter fluid. it ran nice and smooth but i was hoping the alternator would trigger something to make the tach signal or something work. i just read that in another thread. anyways i guess ill figuire it out tomorrow. oh also theres a box that that says nippin dinzno on it and its light blue. do u know what its for?

TomRhere Posted May 25, 2009 Share Posted May 25, 2009 The FPCU has a 6 pole connector, some units are Black, some are Blue. This may help; http://mshoup.us/docs/fsm/EA81/83/ Quote Link to comment Share on other sites More sharing options...
