Jesus!!! This car will not start to save humanity. It is a 95 talon with the original 7bolt block. The head has been rebuilt no leaks no nothing. Im using a 1g green top cas(jnz tuning-harness) head gasket is fresh. I have replaced the MPI fuse, engine coolant sensor, fuel pump, injector resistor box, transistor, coil pack, anything u can think of. I have compression, i have spark on all four, i have fuel to the rail. :banghead::banghead::banghead:. I can not figure this one out. my injectors has been inverted at the ecu(no link, no chip) my firing order is 2314
4321. I Honestly do not know what to do. my mechanical timing is dead on not even half a tooth off. When i try to crank it, the rpm needle jumps as if its going to start but it never starts EVER. Should my firing order be 3241
4321.
I am completely lost and definetely need some guidance. :cry::cry::cry::cry:HELP!!!
 
I would double check the CAS, never hurts. Hate for it to come down to something your swore was right. If that is wrong it would be trying to fire at the wrong time. Posibably fuel related, when we brought my friends 90 talon home it had a no start issue and we went through everything, had spark, fuel to the rail, injectors were good, good plugs, right firing oreder. Ended up being a piece to the fuel pump was missing and he wasn't able to get enough pressure to run on. Do you have a FPR?

Yes I have the stock fpr. What peice to the fuel pump are you refering to.

Did you install the CAS correctly? My bet is the CAS, I had the same problem and slightly turning the CAS solved the problem. Page 8 and 9 on the link below will be very helpful.

Which way did you turn the cas? Im going out today to turn the cas by hand and pull my injectors out to see if they fire. I have spark all day(strong spark way better than i had when i had the 95 sensors in). Today is trouble shooting
 
Well.. on my 96 talon I know the exhaust cam gear has 2 timing marks.... Maybe you lined up the timing marks 180 out?? I did... and had the same problem as you are having.

But theres only 1 dowel pin and its suppose to be facing 12'o clock. So nope thats not it.

Do you have a way to verify your numerical fuel pressure value?

No way at all.

OK,:ohdamn::cry::banghead:.....Made a mistake, Took the injectors out hook the harnesses back up took the spark plugs out and wires. i started turning the cas and BOOM!!! Car caught on fire. But with that being said, i didnt see any fuel coming out my injectors. The car caught fire because the injector blew off the fuel rail and gas started going everywhere. Im really sick of this shit. Wut other car besides the evo and other dsms can i swap injectors with. Im asking because there is hardly no DSMs in these junk yards and definetely no Evos. I dont know if the rail has to build up a certain amount of pressure before the injectors fire or what. With it installed the injectors soaked my spark plugs. Could they just be stuck open?? Im just goin to sell it, i cant take it anymore
 
Calm down man. I know its frustrating but hang in there. I seriously doubt you have four bad injectors. Your injectors should click when you spin the cas. If not then you need to check the incoming power to the cas and the output signal. I use an led test light to verify 5v sensor pulses.

when i turn the cas none of them clicked. The only thing that click is the spark plugs firing. But even with the original sensors it did the same exact thing. Couldnt hear them click. Its just pitiful man
 
You need to verify that your getting the cas trigger pulse to the ecu on pin 88 with that led test light.

If they're not clicking then your problem is your injectors not firing. Go to your local autoparts store and buy a noid light (return it when you're done if you don't plan on using it again). Plug it into your injector harness and crank the car. That'll tell you if the injectors are actually pulsing.

I'm the one who had the no start on the 90 talon. It ended up being the retaining cap in the fuel pump neck. Previous owner put a new pump in but only put the oring and plastic spacer on the pump, not the retainer cap. All my fuel pressure would bleed back into the tank without it, even though I was getting fuel inititally up to the rail, it wasn't enough to even spray out of the injectors (and trust me, it LOOKED like it had good fuel pressure).
 
Buy the noid light.

just forget it, injectors are working...compression is beyond repair. Im selling it. Im going to come back a little later, when funds are right

heres the conclusion. I have fuel, spark, injectors are clicking..The only thing i havnt mentioned is compression. Im going to leave it at that. it was 60-50-50-50 before i changed the headgasket. the HG was the cause of those numbers. It acts a little better now, but still wont start

Its a DSM, going into any project your ALWAYS expect dificulty especially with a DSM there a headache and a half when the don't work right! a good way to check if the injectors are working properly is to get a 9 volt batery and a a set of aligator clips. Fill your fuel rail with fuel and give the injectors power. You will burn through the batery prety quick though if you don't get one of the big 9 volts. This is what we did on Tyeler18's car, then when we figured out they were firing we go a noid light and made sur they were getting powered by the car. if all that is good it is no doubt fuel pressure if everything you stated before is true. Sounds like compression could definately be the problem, if so put it aside for a while if need be and build it or find a used motor.

I understand that these cars are old. What i dont understand is that as soon as i broke those valves on my old head and put this head on, it dosnt want to start. Let me give you a run down. I drilled a hole in the original head, i bought another head i didnt take it to a machine shop or anything(previous owner did). i had everything except valves, springs, rocker arms and cams. I swapped everything over and the car started right up. I didnt torque the tensioner pulley bolt:ohdamn:, i rev the car and it jumped timing. Broke valves, i bought a entirely new head had everything done at the machine shop. Now it just gave way on me.
 
Ever consider that your timing is causing low compression across the board?

My mechanical timing is dead on.

I "THINK" I may have found out the problem. Not really sure though. i have a dead cell in my battery. So when i take it to O'reilly's and they charge it, it still dosnt have full charge:banghead:..I will be troubleshooting tomorrow(monday) too. So going to test my luck with battery and everything else
 
Good luck man. Im still grinding my gears on this one. A perplexing problem indeed.

LOL..me too man. I hope this is the problem, along with those injectors too. I had it making black smoke, then i found out my injectors were'nt clicking. I believe they were stuck open, along with a dead cell in my battery. So i've been doin this lately:pray::pray::pray::pray:. We'll see!!
