i have bought this car rebuild the engine, and after driving the car for about 1 week it just shut off, i had nothing i mean not even the door ding. has not started since, got fuel and spark, its in time and the problem is with the injectors. they will not light a nodi sp? light so what do you guys think? ha i ahve also tryed a computer
By "in time" do you mean ignition or cam? It is possible that the timing belt has slipped.
You have checked for spark at the plugs?
How have you checked for fuel?
I doubt it's the injectors. They don't just "fail" as a group.
TFI module maybe?
How much backlash is in the distributor rotor? (ie, how much can you rotate it by hand?). Munched a dist/aux shaft gear perhaps? What oil pump did you use on the rebuild? High pressure? A big no-no on these engines.
With the KOEO, and the dist hold down loose enough to rotate the dist, can you get the fuel system to prime? You should hear a click from the injectors and hear the pump run for a sec as you turn the dist one way or the other.
Well As far as I know all the injectors should fire at the same time. They all fire from the same signal. So I would tell you check your wiring.
yea, everything in new. i thinking it wiring as well.
A bad TPS or its associated wiring can put the EEC (computer), in the dechoke mode... Meaning the injectors are shut down...
Run the diagonstic codes, you may well find your problem...
ecu wont put any codes out.
Well, that's a problem.
It's either wiring or the ECU is bad. Since you replaced the ECU (known good one?) then wiring is probably the issue.
yes, well as far as i know. its a newone from autozone. i called about a harness today, ron (badbird) said he has one out of a 83 tc. i hope i can get that one, i miss the turbo feel
i had nothing i mean not even the door ding. has not started since,
I think ya barking up the wrong tree.....
you have now power inside the car at all??? I would check the fuse links that hook up on the starter solinoid, on the bat side of it, you might have burt the hot feeds to the fuse box
I mised the ding part... BogusSVO is correct, it likely has a bad fuse link...
You just grabbin for a harness is likely gonna get you in trouble as well. I doubt a T-bird and Stang harness are plug and play with one another...
see thats the carzy thing, now i have power in the car. and before i had trouble with the headlights or dash lights, somewhere i had trouble and i cant remeber excactly where. thats why i want to get a whole new harness. i have traced wires and found nothing. i mean there are three mechanics in my family and everyone is stumbed. i am close to pulling the engine and getting a tc, but then i wount have the rare-ness of the GT TURBO. some time i could just :yuck:
you guys are great thanks for all the suggestions, i will be working on it this weekend
Well, this would all be useful info to know when trying to help with a no start.
It's either a dead fuseable link or two or the ignition switch is bad....which is highly likely on an 80's Ford.
but if the switch would be bad would i have spark and the fuel pump running. its just the "power" to the injectors. but i guess i have to keep everything in mind. its just weird
Well, the "power" to the injectors comes from the ECU....you've swapped that, and unless you have 2 bad ECU's.....
If the ECU does not get the signal to cycle the injectors, you could have spark and have a primed fuel system, but sill no start. Did you check the TFI? Did you check the wiring to the TFI? Did you do a wiggle test on the TFI connector? Pull the TFI connector and look in the end of the plug. Are all the connectors inside all lined up, or are one or two pushed back in the plug body?
Did you turn the dist like I mentioned with the KOEO?
Then again, it's hard to play mechanic over the internet.
no i havent tried that. i will though and what you are saying is making sense. i may try to night, i have been sick lately, and havent wanted to go outside, for the cold. i will get back with ya
chuck w, about the koeo test, it should do that even after the fuel pump as ran??? i am working on it tomar! whaoooo!
check your grounds you have just pulled the motor and alot of the times grounds get forgotten. or broken when taking them out.
does the car have rust on it. check the Ecu Ground did you forget that. bc 2 bad ecus is tough to belive.
ITS RUNS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:evilgrin: it was a wire! and it was only about 1 inch bad section. yes!!!!!!!!!! it runs you guys dont even know:rollin:
i cant help it................... YAY it runs!!!!!!!!!:D
congrats enjoy the ride.
It's amazing the troubles you'll have with 20+ year old wires that have spent their life undfer the hood with a turbo ;) (That's why the Tbird is getting a new harness with the MegaSquirt)
Glad it's running.
i know its just crazy! me and my step dad worked on that thing for weeks, got pissed and stoped, so then i took it school and worked for a other 40 hours and nothing. started yeasterday ran some test found nothing. step dad comes up and says, its has to be over here.(refering to the wiring on the driverside) he puts his hands on these two fuseable links, that are about 3 inches from eachother, and says man the wire feels realy soft! so we run some restance checks sure enough thats it. so we put a piece of wire in and try to start it, and nothing i was mad!My grand father said to you have everything pluged in, lol ........ my uncle say no, the injector harness is not pluged in. so we do that crank and it started right up. she has a mis but we were runing out of time cause we HAD to go eat,cause of the hole family tradtion thing:yuck: . so we continue today!!
