he might be if that were the case but it's not..it's cfi if you read the whole thread
anyway to the OP...on top of the throttle boby where the injectors are there is a shreador valve / fuel pressure test port...put a gauge on it and test the fuel pressure when you turn key on it should power the pump up briefly and indicate pump action / pressure...if it doesn't fuel pump circuit needs to be troubleshot.........check fues box first for any blown fuses..but my gues is since the fuel pump draws it's current directly off the selonoid through a relay..you may have shorted one or the other when battery was hooked up backwards....the wires to the selonoid for fuel pump action on the fender mount selonoid should be on an eyelet black and blue wire at least it was on my 85 cfi stang........check the fuel pump relay under drivers seat..it may have gotten fried

i wish i knew more about the cfi systems like that so i could help out better. all i know is they suck and thats why they only lasted 2 years with ford but gm didnt know how to get out of the retarded age and move to efi

Well we went ahead and tested a lot and checked to see if wires were fried.. They all seem to be fine, the old owner did some modifications and took short cuts doing so... We think its some thing to do with the pump and starter but not sure

trust me I learned more than I care to know about the cfi!!..when I first bought it I didn't think it was much slower than a carbed one until I rebuilt it all with a cam, roller rockers ported head..performer 302 with 2 barrel egr plate, fulll exhaust and 2000 stall and 3.73's with an aod....and my bro's stock 86 gt spanked my ace!!!.......that cfi stands for crappy fuel injection..no way to tune it......so I heaved it and converted to 4 barrel and went from a 15.4 in the 1/4 mile immediately to 13.70's

hahaha thats why im happy mine came with a carb, actually i test drove a 94 gt over the weekend and that thing didnt even have as good of a throttle responce as my carb does mine is snappy as hell and that thing was just blah

We are going to try and take a 12gage wire from starter to the gas and see if that would work...

mjr46

and ignite it??? wtf??? your doing it all wrong..I told you where to start....the wires that power the relay under the seat.....is on an eyelet on the starter selonoid= I believe a blue and black wire and I believe that bridges into a fusible link that you may have toasted..and the relay is under the seat....hint hint..may have fried it...and in the behind the left tail light is the fuel pump reset/collision trip black box..check all this....the system in that car is simple and if you understand what it consists of and where all components are then you can figure the prob out...and dont you dare apply 12 volts directly onto the injectors..do what I said and you can resolve issue......a test light will help you locate some probs

ak5150

we took a test lighty thingy (what ever its called) tested wires and what not it gave us red lights for almost everything except for the wire that goes from the starter cilinoid to the pump, that wire was tosted and we were going to replace that wire... i will try this tomorrow what you have stated before i go ahead with the idea that the guy said he feels it is... there is no noise when we turn the car into on position he said normally there should be a gas noise of some shorts, also there was 100% no gas coming up into the car it seemed like but we kept turning it over when we pushed gas in manually through the breather but it just shut off

where is this "and in the behind the left tail light is the fuel pump reset/collision trip black box"

I did not see this where is in by, inside trunk?

mjr46

behind left panel by tail lights..you'll have to look around..it's only about 2 x2 inches in size

HACKGT350

its got a big red button on top of it. its called an enertia switch. if you smack it with your hand you can trip it thats how sensitive it is. we play games on each other at the dealer here. we go around and smack the quarter panels where the switch is and trip them so when the other guys go to start the car it wont run and they have to figure out why its lots of fun lol
