Make sure every little thing you disconnected to make room to work is reconnected! Sounds like your AFM is not hooked up. :devious:

Update

i messed around with the afm and now the car will start and idle w. spray start. if you hit the gas it will rev but after a min or so starts to bog out and dies, hitting the gas does not help at all.

fuel problem right? i checked the fuel pump, its pumping

any ideas?

Could be fuel filter, gas tank, or anywhere inbetween. I would start with a fresh fuel filter to rule it out and run the fuel pressure test that is in the fsm if the problem still exixts. How long did the car sit before you purchased it?

[ALT_255]

i replaced the fuel filter, i can now get started w. starter fluid and it will run for aprox. 2 min and then it starts to bog down.

i was trying to rev it up to clear out anything stuck in the injectors

and it bogged down real bad and the engine started to smoke from the area around the injectors?????

bad/clogged injectors?

thanks for the help so far sblake and frank

Check to see if you have the gas feed and return hoses on correctly. I've done this before putting it back together at night:stupid: me

[ALT_255]

went and checked it organ, their right... that would be a funny way to fix the car...

anyways does anyone in IL know of a shop that can clean injectors? i think they are working fine, i did the test w. the long screwdriver and they clicked ok..

anything else i should try?

p.s. the car has ben sitting for about a year and the lines going into the injectors were completly mealted, like they were disolving in my hands when i got them off

The reason I asked about that is when I bought my 78 in 1997 it has been sitting for quite a while and the gas tank had to be replaced because of all the sediment that had developed over that period of time.

i got a fuel pressure gauge and put it on, and started her up.

i have found that if i stick a wrench up the afm to hold the flap open untill the preasure gets to ~36 psi the car starts right up and will idle for a while, ~2 min, while it is idling i can rev the car up and everything, but after a little while it starts to bog down and smoke comes from down by the headers...

im going to fill the tank all the way up and see if that helps the pump and if noti guess i will replace the fuel pump and see where that puts me...

is this a good course of action? other things to try?

[sblake01]

When it starts bogging down, is your fuel pressure dropping?

[ALT_255]

yes it goes down to about 10-15 psi
