1991 ford taurus with 3.0 liter, wont start after shutting off.
The first time it back fire and then started and ran fine.
Drove 15 miles and parked, after about an hour tried to start, it back fired and a little bit of throttle it started and drove it 5 miles. Notice the tach was not reading (inoperative). 5 minutes later the car idle rough and won't rev up and stall. Need information of checking sensors if they are the problem. Any suggestion. help

hello rusty,

The best place to start is with a self test of the computer [pcm] and see if there are any trouble codes. I would also test the fuel pressure, it should be around 30 psi. Check the ignition coil for having a nice blue snappy spark and that it makes it to the spark plug.

Instructions for self test. Get back with me after checking these out,, Glenn

Also tell me the mileage, and tune up/repair history

Ok,

That code 19 looks like the problem you as describing. The cam sensor or CID [cylinder identification] synchronizes the fuel injectors to fire at the correct time during start up. Otherwise the pcm has to guess based off the crank sensor and it takes longer to start. Here is the pinpoint test. I only gave you the first 2, hoping that would be it. Just reply if those are in spec. I'm going to assume you ran the engine running self test with a cold engine, that must be at operating temp or you get ect codes [21], if that was not the case, we need to check it out, it also can cause a hard start.

Would not find CID, this unit has ign. coil with 6 secondary towers on top and only 4 wires,(red/grn, wht/red, yel, yel/blk. And the cam sensor has (1)org, (2)lt blu, (3)grn, (4)red/grn. Check (cam)ohms between each terminals. 1-2 was 1.228, 1-3 was 1.228, 1-4 was 87.5, 2-3 was .001, 2-4 was 1.316, 3-4 was 1.316.

Thank you very much for pointing me in the right direction. I replace the cam sensor and it started right up. The tachometer is working and throttle is responsing as before. I'm limited with tools and test equipment but I still made it. I really appreciated your qualities.
