a few months ago i bought a 94 gt and i got about 20 miles from the guys house and it stared running like crap and then wouln't even run at all, so i drove the three hours home to get a trailer then three hours back to the car then three hours back home again it was a long day, lol. turns out to be the fuel pump problem solved. i got it out on the road for the second time and got about a mile and it just dies, i was out of fuel i only wish. the dowel pin on the cam broke and no one had a replacement so i bought a new comp cam. i pulled the engine out installed the new cam a full set of gaskits and along with a new trickflow trackheat upper and lower intake. i finay got the engine dropped back in and everything hooked backed up and went to start it and it turns over but doesnt fire.
i checked the sprk and it has good spark then i checked the fuel and it has good fuel pressure 40psi. im not sure what to check next?
some times it tries to fire but only for a second and once it back fired through the intake. there is a ticking noise when im turning the engine over but when i go full throttel it stops.

any hels is appreciated.
keep in mind im only home on the weekends to work on it so progress will be slow.


here is a list of engine mods

trickflow 185 cnc aluminum heads
trickflow trackheat upper and lower intake
70mm throtel body
1in trickflow intake spacer
30lb injectors
comp cam extreme energy cam

first welcome to the site

The distributor is a common prob with our cars. so ck into that. Stock replacement or new ford is good. MSD may or may not cause more probs down the road.

Also ck the harmonic balancer for slippage or rubber squeeze out.

the key on the crank shaft that holds the harmonic balencer in place looked fine, I'm not sure what you mean by rubber squeeze out? the distributor is pretty new but it could be defective or something.

i know the wires are right i double checked those, i might have put the dizzy in 180 out. when i put it in i made sure #1 cylinder was on tdc compression stroke then dropped the dizzy in with the rotor poiting towards the #1 post. is that right? i had the timing set at 14 degrees advanced be for and i marked it be for i pulled it so it should be close.

when in put the cam in i had #1 cylinder on tdc then aligned the timing marks?
thanks for the help guys
i wont be home until Saturday so i wont have any updates until then but if there is anything else or any suggestions you might have feel free to post em.

as the HB gets old the rubber between the hub and the pulley gets dried out and it may cause the HB to wobble, causing vibrations. It can also slip, thus giving you the wrong timing readings.
You can usually see the rubber squeezing out from under the car looking between the HB and the oil pan.

my vote is for the cam timming being out. if your 100% sure the spark plug wires are ok and that the dizzy is in right( not 180 out) then i would say the cams off. Backfiring is caused by incorrect timming so check all of the timing components as listed above.

i had the distributer in wrong but now i have another problem. it will star up but it wont idel as soon as i left off the gass it starts to die but i can put i can push the throttel a littel bit and keep it running. is there anything i can adjust or something to make it idel on its own? i think i have the timing close set at about 14 degrees advanced and running 40 psi fuel pressure.

i really appreciate the help so far guys.
thanks

reset timing back stock at 10 btc. check all vac lines. reset tps and clean maf/iacv. after you set everything back to stock specs and it still wont hold idle its got to be timing. maybe your cam timing is off a little bit??

i think got the timing set back to 10 btc. to get the car running i have to press the throttle in a Little bit and crank it over quiet abit to get it to fire and start, and as long as i keep presser on the gas pedal it will stay running about 1/4 throttle. as its running the hole car shakes. the only vac line that i found not hooked up I'm not sure where it goes to. on one end of the vac line there is a container looking thing with a electrical plug going into the bottom of it where does it hook up at?

does the shaking increase with rpm? Does it ever smooth out?
If it does not stop shaking then chances are your harmonic balancer it toast and needs to be replaced before it tears your whole engine apart.

it gets a little better if i raise the rpms up to say 1000 but it still shakes and never goes away.
i adjusted the tps and i could not get it to go below 1.07 volts. when i try to adjust the timing i pull the spout connector out then start car and set timing shut car off and reinstall the plug and it jumps up the timing like its supposed to but it jumps it all the way up to the end of the scale on the balancer. all the threads ive read it only jumped theirs up about 4 degrees. when the spout is out the car wont idle on its own at all i have to keep constant pressure on the throttle but as soon as i put the spout back in it will idle on its own for about 10 minutes, it will hold at 800 rpm for a few minutes then go up to 1200 rpm for a few minutes then fall back down. i dropped the fuel pressure back down to 40 and it doesn't change the way it runs.

PHYSICALLY GRAB the balancer and see if you can wiggle it. If it moves...at all, you've got a shot balancer and its slipped and youre timing is innaccurate.

even though the car will start and idle for 5 to 10 min do u guys think it still could be the cam timing? is there any write ups or directions you guys can give to help check the timing and fix it? standing at the back of the car listing to the exhaust it kind of sounds like it has a miss. I'm going to check the balencer and the cam timing today

i put the #1 cylinder on top dead center compression stroke then pulled the timing cover off and the two gears were dot to dot. i don't know how to check it any more than that. i guess the nuts on the intake vibrated loose or something causing a vac leak that might have been causing part of the problem. the balencer looks and felt OK no movement.
