Its probably got an electric igniter rather than a coil, either way it sounds like your not getting for in your piston cylinder.

Hi Trevor, Please let us have the engine type, as that will help us help you diagnose the problem. In the meantime here are some suggestions. take off the ducting to the turbo and look to see if there is oil contamination in the inlet from the turbo. It is not unusual for those units to become worn and then begin burning oil by leaking it past the seals. If the turbo shaft has any drag, that would also indicate excessive wear, indicating a replacement is required. If the head and rotor are damaged or worn, that would usually present as a problem with starting, especially when cold. Defective injectors could also cause the problem. Piston rings may also be damaged and worn. It is advisable to service turbo induction vehicles used in dusty conditions every four thousand kilometers, much less than normally recommended by manufactures. I would hope that you have replaced the filters with new and that they are of good quality. If they are substandard, they could be blocking fuel flow to the injector pump. Let me know how you get on. Regards John

My 1991 ford F350 w/460 EFI is really hard to start after sitting for a week or so, and once I have it running it does not want to rev. It pops and misses, almost like a bad mass air flow sensor.

Sounds like a lean misfire condition. Have you run a fuel pressure test? Should be 55-60 lbs. If pressure is ok during idle and reving, Ttry disconnecting MAF and see if any difference on accel.

I have 1991 GMC syclone turbo charged. It has a full tank of gas and is getting spark but wont start

step one- need silence- insert key - turn to on- not start- listen for fuel pump whine- if here nothing- check 1- fuel pump fuse
2- fuel pump wiring (double check your ground!). if pump still does not make whine(pressurizing) your pump is gone. an intermitant pump can be a ground issue or a bad pump most times....

1991 eagle talon non turbo will turn over but wont start just replaced the computer in it and havent even drove it a mile my brother thinks its the fuel pump because u cant here it kick on when u first...

Hello, Joey, thank you for the direct question. Here is an easier more accurate way to troubleshoot your problem, other than the one proposed.

If the fuel pump is in doubt, check for fuel pressure at the fuel rail on right side of the engine. With the key in the run position you should have about 40 PSI. If pressure is present, but low, check for a restricted fuel filter and voltage at the connector, on top of the fuel pump. You should have 12 volts there. A lot of times a bad ground will cause a drop in voltage. The pump will still run, but will be weak. You should be able access it from under the backseat.

Another area to inspect is the CAS. If the ECU does not receive a signal the engine is trying to start or is running, it will not fire the fuel pump.
I hope this info was helpful & good luck with the Talon.

Has he checked the turbo, pressure? How is your air filter? could be a short to the coil for the pump Try running a couple of tanks of amsol additives cleaner, may just be carbon deposits forming on your injectors.

Car will start for a few seconds then dies.

Still sounds fuel related to me. Getting minimal fuel enough to start & or rev, but not maintaining proper pressure required. Try this. Get a can of WD-40 ready, remove air intake hose at throttle body. Start car & when it starts to begin to die, spray some WD-40 into front of throttle body & see if engine continues to run, as long as you keep giving it squirts of 1-2 seconds. If it does, change fuel filter first, but be prepared to do pump too. If you can get a fuel pressure test done on it, that would be even better. Let me know what happens.

Engine seems to run good then goes downhill

Have a look at the fuel pump it looses pressure when hot which means it is due to be replaced.
