Just got done reading after searching for a while.. my fuel pump isnt priming,
after searching i found that the reason for the pump to not prime could be a bad fuel pump, or a bad main relay, or possibly a map sensor..
the car cranks fine i have the hose that goes to the fuel rail disconnected to see if fuel will come out when priming and im getting no fuel, and the pump isnt priming...
its a 88 hatch with a b16a1..
Any ideas?

 

bad main relay, especially since your gauge doesnt work.

 

does anyone know if an Eg main relay is interchangeable with the Ef main relay?

 

underneath the driverside of the dash all the way to the left you'll see the main relay (little black box with a 10mm bold holding it on with a plug into the bottom of it. While you turn your key on keep a finger on that little box. If you dont feel a click when you turn the key, then the relay is bad.

 

I had the same problem in my hatchback. Power at the pump, cranking, but no fuel in the fuel lines. You should hear it click as your CEL goes off when you turn your key to the second position as well.

 

I'm having the same problem but my fuel gauge works. So I think with your situation something is bad with the wiring.

 

ok i put in a new fuel pump, still didnt work.. then checked the wires in the back for power leading to pump and realized i wasnt getting power. So i went and got a new main relay and the fuel pump is still not coming on. i checked the power at the plug that connects to the main relay with the main relay connected, and the yellow and black single wire does not get power. I checked the wires in the back seat again after the new main relay and still no power to the fuel pump. so i unplugged the fuel pump plug in the back seat and checked the main relay plug and now it had power. then plugged the pump back in at the back seat and checked main relay again and no power this time.. so it seems by plugging the pump in is somehow causing the power to be cut off??? help for ****s sake im getting discouraged

 

the fuel gauge is working now i cleaned the plug and its getting power. i hooked the pump up straight to the battery and it works to by the way

 

when you turn the key to prime the pump, does your check engine light illuminate at all?

 

this is wat i always do wen this happen run a wire from the power for the fuel pump to to ur underdash fuse box there u have like 4 slots wer u can plug a connector in i think its the 2nd or 3rd dnt remember but try this then turn the key to on position and watch it work might as well put a kill switch while ur at it dnt take but 30 mins to do all this well hope this helps.

 

no the check engine light doesnt come on.. and yea i thought about wiring the pump to a switch or to the ignition but i wanted to get it to work right.
I wired it straight to the battery last night just to get the fuel pump to kick on and it did so i could attempt to start it.
ALso i checked for spark last night on one of the spark plugs/wire and wasnt getting any spark either. no fuses are blown, and i looked inside the ecu it doesnt look burnt out any where.. also the fuel pump wire gets power right at the ecu, but not at the main relay for some reason...??????????????????
by the way the car has been sitting for a while.

 

also i heard the main relay is supposed to click once when u initially turn the key, and another time like 2 seconds after, mine is only clicking once when i first turn the key

 

so i got no spark, and the main relay is not turning the fuel pump as it should.. no blinking lights on ecu, no blown fuses, brand new fuel pump and main relay..
whats that sound like? distributor? igniter or ignition switch? anyone?!

 

Quick question Mike banX, did you buy an oem fuel pump or one from like pepboys or kragen? Asking because the one I bought I had to tap into wires because new fuel pump had it's own connectors.

 

i got mine from advance autoparts but it didnt help cause for whatever reason im not getting power from the main relay

 

if your check engine light does not come one there is a problem with the ECU. can you give me the specs on your car? what ecu are you running? obd0 or obd1?

 

when you installed the new relay, did you disconnect the battery first?

 

if the engine light does not come on when you turn the key for a few seconds, then there is a problem with your ecu. do you have another ecu you can try?

 

I wouldnt say it's your ECU without knowing your ignition switch is good. Check your ignition switch

 

yea i disconnected the bat.. no i do not have another ecu.. i was thinking ignition switch too..

 

i read somehwere that if the light doesnt blink on the ecu when the key is turned its faulty.. mine doesnt blink at all, cel doesnt come on, main relay only clicks once, not getting spark and not getting power to the fuel pump.. also the turn signals werent working the first time i tried starting it..
by the way the car has been sitting for a while

 

CHECK YOUR IGNITION SWITCH. Its a big prob with the ef. no check engine lights are going to come on no power to your fuel pump no power to ecu and no spark. Come on if the switch that turns on everything in your car is only working half *** because all the solder got to hot from the switch and melted away guess what only half the **** in your car will work.

 

I wish people that asked for help would actually listen.....

 

lol...I thought? never mind. All we can do is try but your right the key word would be listen.

 

yo tjchad you were the first one to say something bout the ignition switch, and you just said it today.. I agreed with you by saying i was thinking ignition switch too.. therefore i did listen.. I will check it just didnt get around to it today..
505turbo: i am getting power to the ecu.. just no cel, no spark, and no power to fuel pump.
I appreciate the help, and the more that chime in the BETTER.
