Question about 1990 Ford Tempo
Sounds like a intermitant coil winding in the crank sensor but agin as is the case with a lot of these questions i do really need my head under the bonnet as their are many different varients on many models of cars and trucks and this is one i have never seen before ,this model is not in europe and to liken it to scorpio or a mondeo in europe is difficult as although the running gear may be the same the engines used in american cars differ from its europeon cousins ,we do not have cheap petrol hence the popularity of fiats and alfas ,Vw golfs and ford fiestas ,small cars which are rapid ,go around bends at great speed and manual gearboxes and most of all do 100mph and 50 mpg

Was looking at posts and other sites. I take it that some relays are even under seats. Anyway, Apparently the ECU relay and the ECC relay are linked. When properly operating the ECC brain sends a signal to the ECC relay and the ground wire is tan/green. The brain can be throwing the signal and the relay terminals are not receiving the signals, so the relays cannot switch.
Although you have replaced some relays, you need to check your plugins for these 2 relays.

if the battery is not much good then you will get issues like this also being a ford I would check the earth connection from the car battery to the car body, the main feed. also there is another o the gearbox and another that runs to the altenator, these are all common poor earth problems. ensure they have a good conatct.
Secondly have you checked the fuel relay is not loose or maybe on it's way out, this again is not unusual, if the relay fails then it has an electro magnet inside, poor powr from the battery will make it stick either open or closed like a light switch kinda, you should here it ticking at the fuse box when the key is turned, also immobilisers often use this part of the cars wiring to stop fuel coming to the engine as a security measure. Maybe thats the issue the immobiliser shutting the relay down.
I would certainly check that first as its super simp,e to replace.
p.s if you need more info get back to me

There are several possibilities, but based on how you described the symptoms I suggest a profile igniton pickup. On these systems the failure usually begins as dropping a cylinder occasionally,like a misfire,mostly during high underhood temperatures,will manifest into stalling and finally into a stall with no resart condition. Symptoms are most likely to occur in summer. The pickup is inside the distributor and the distributor must be disassembled to install it,the trickiest part being the removal and installation of the distributor drive gear. They are iron and easily broken. The simplest solution is another distributor. The ignition modules typically do not fail in this manner,but this is classic for the pickup coil. A code for loss of pip signal should be present, it is possible for a code to not be present,though very unlikely. Having worked on these systems for years this would be my first area of diagnosis.
