Check the fuel rails most the japan vehicles don't have screw valve. If you don't see a screw valve you will have to slice in the main fuel line in to your guage.

My brother has leant me his 1993 Ford fairmont EB11. A red light is flashing intermiitanly it looks like a fan in some kind of cylinder. Could someone tell me what it is?


  • Full instrumentation pack (four ancillary guages plus tachometer) - with volt meter & oil pressure guage.
  • Speedometer, odometer, tripmeter, fuel guage & water temperature guage standard in addition to the above.
  • WARNING LIGHTS: High beam, rear window demist on, turn signal / hazard light, alternator fail, lights on, park-brake on, washer fluid low, radiator coolant low, cruise control indicator and low oil pressure.
  • AUDIBLE WARNING CHIMES: low fuel, lights on, low alternator charge, low oil pressure, high coolant temperature and brake failure.
  • Trip Computer standard featuring fuel consumption figures, distance to empty, average speed & time display.
I found this site, no mention of the fan in a cylinder, but I'll let you figure it out. Hope this helps.

I have a 90 chevy k1500 350 tbi with same problem! I have traced problem to... after turning on key fuel pump kicks on when u crank it over injectors shoot gas and truck starts! After few seconds injectors stop spraying and truck dies! This can happen many times over and over! Eventually sometimes truck stays running and all is great! I changed ignition module, oil pressure sending unit (which i was told controls gas after vehicle is running) fuel filter, computer, fuel pump relay, I am at a loss now! Hope this helps and hope someone can help me!

Sounds to me like the fuel pump is worn out. They DO wear out. And even though they seem to be working, the brushes in the electric fuel pump may not be contacting all the commutator, thus making the pump weak. It may start the motor but can't maintain normal running pressure (27-35psi). Have you run the car out of gas shortly before this problem surfaced? If you have then it's your fuel pump. It was damaged when the tank ran dry. Even though the pump may seem to be working, it's still badly damaged and needs to be replaced.
Just as Matmenzies has stated, get a fuel pressure gauge and test the pressure. I'd start with a complete check of all your vacuum lines. Check for cracks on the vacuum hose that connects to fuel pressure regulator on the fuel rail. Also, if you can, get a hand operated vacuum pump to check the regulator. If you can place a vacuum on the regulator and it holds, I'd say move on the fuel pump and check it.
BTW, if the fuel filter has been changed, you may want to check to see if it was installed backwards! Some fuel filters are valved and will cause symptoms like this. However, this is an immediately noticeable mistake and you haven't provided enough info for me to say more. I'd pull it and check that it has any flow at all. You could have sucked in a big dirt ball and blown it right into the new filter, effectively stopping fuel flow. Then I'd blow out the fuel lines, just to be sure.
Start with these 2 things and post what you find. We'll go from there.

Hard to start in the morning. Also stalls


This sounds like a fuel pump check valve problem, if the fuel is not kept in the filter and lines by the check valve it drains back into the fuel tank and causes the kind of problems you are having, you can check this by hooking up a fuel pressure guage at the test port on the fuel manifold that supplies fuel to the injectors, run the engine and shut it down, note the fuel pressure at shut down (with the test guage hooked up), walk away for an hour, come back and check the pressure, it should not have dropped more than 5 PSI You can buy a universal fuel injection pressure tester for about $25.00, cheaper than having a shop run the test. If the pressure drops you found the problem, bad news is the check valve is in the pump, the pump is in the gas tank.
