still need help.....frozen lines?

[kennycoulter]

okay here is my new update....havent wrote much for a while. okay i got the car back together, gas tank is full, and the egr pipe is now on. well i think my gas lines are frozen. car is in unheated garage. the engine turns, turns quick, had the battery charged, the coil is very strong, and i tested the spark. i have the hood off to get at all the stuff i had to. so i can hear things better too. i put a new alternator on recently. here is what it does:turn the key to the run position, (i used to do this a couple times before turning over to get fuel up top), i hear a click near the fuel rail, and a click afterwards under the seat, but i do not hear the gas spraying through the injectors. i used to be able to hear them squirt........kweeeeessshhhhh! but now only a click pause click. now the other key position: turn to run, and put screwdriver on solenoid(my key), engine turns fast, hear a clunking, finally realize its the vam opening and closing(never heard this before), gets spark(what are plugs supposed to be gapped at again?), and sometimes after wards ill here something spool down or clicking. wasnt sure if it was the new alternator or starter or fuel pumps? sounds like it is coming from distributor area. any ideas? does this actually sound like frozen lines? if so, what to do? should the vam clap like i hear? please help....p.s. ill become a "member" when i get my new job.

Do you hear the fuel pump running?What concerns me is that you have had to turn the ignition key several times in the past to get enough fuel to start.You may have a bad fuel pump or you may check your hot wire that runs to the starter solenoid,as my 86 svo had a similar problem that turned out to be the fuel pump hot at all times wire.

You should here the pump spin up when you turn the key. The click under the seat is the fuel pump relay.

You might try the fuel system reset button in the hatch area behind the plastic siding. It may have tripped on you with all of the other things you were doing.

I believe Pat_in_LA told me that you can run the fuel pump by supplying 12v to the small plug of the computer harness where you connect the EEC code reader. You might try that to see if you hear the pump running.

You might need to pull one of the fuel lines and direct it into a container and turn the key to see if you have flow. Be Carefull! Make sure the gas cannot get near a spark.

The hot wire I spoke of goes to the relay.My 86 fuel pump relay would click and if I cycled the ignition switch would finally start for a few seconds and then run out of fuel.You should do as gaboy suggests and check for the presence of fuel in the fuel rails or lines. If you don't have fuel pressure I would check for power at the fuel pump.If you have no power there I would trace back to find power and narrow it down from there.

oh man. well the car never really ran, so it would sit for a week, then i would go to work on it. thats when i would turn the key a couple times then start. i dont think i ever heard a pump spin up. any remarks about the flapper door? it banged around alot.

[kennycoulter]

so just a wire from the battery to the connector/tester would turn the pump on?

[GAboySVO]

Kenny,

I was mistaken about which test connector. It is not the small one, but it is the larger one and the wire goes to the lower right one as you look at the test connector with the lock mechanism facing up. You will need to turn the key to on position as well. I just tested it on my car in the garage and I could hear the pump hum.

This is how you empty your gas tank before removing it.

As far as the VAF flapper goes, it maybe that as each cylinder tries to suck in air the door tries to open.

[kennycoulter]

so no worries on the flapping? the only thing i have set up different is the egr is on. and no i.c. brackets. oh and my heater core broke so i have my coolant lines connected directly with a loop.

hey, does the adjustable fuel pressure regulator have to be used in conjunction with the 255 lb/hr fuel pump? i guess my fuel pump is bad. i AM DEINITLY GETTING GOOD SPARK.

[kennycoulter]

ok i cant wait for shipping times, so im just going for the regular replacement pump. any tips on installing that the haynes manual doesnt cover?

[SVOeric]

I wouldn't replace the pump wthout making sure that is the problem. Have you tested the pressure ?

Throwing parts at problems can get expensive!!

Tips on replacing the pump -- a empty gas tank really makes things easier.

[kennycoulter]

i figured i could clamp the line. i was told to do a test buy having a wire from the positive to the test connector. i only hear the clicking coming from the passenger side.....and i was told i should hear the pump spin. how do you test pressure? there isnt a valve on the line like newer cars.

[kennycoulter]

anyone?

[GAboySVO]

Kenny,

When you turn on the key, you should hear the pump run for just a few seconds. At that point, there should be pressure on the fuel rail/line. You will need a guage that threads onto the shrader valve (looks like an air stem). There is one on the fuel rail and one in the fuel line near the firewall. Maybe Autozone has one you can borrow?

If you are not hearing the pump prime when you turn the ket on, then there is a wiring problem or a bad pump. Check to see that you are getting voltage to the pump when the key is turned to the on position. You could have a broken wire or a bad relay. The 84 has to pumps, one in-tank and one in-line.

[SVOeric]

if you have clicking -- that sounds like a bad relay -- it should be a 3" or so green thing under the drivers seat.
