Question about 1989 Ford Escort

Open Question

My 1989 ford escort with throttle body injector has no computer. There is no fuel pressure or ignition. Ijumpered out the ignition vacuum switch and got ignition, but so far I have no fuel pressure even when the vacuum switch was jumpered. I have exposed the fuel pump and am going to power it directly.

SOURCE: Checked Fuel Pressure Regulator on 93 Ford Tempo GL 2.3 Liter.

As far as I know without checking it personally it sounds like it could be one of three things (in order from easiest to hardest). Clogged air filter, worn timing chain, leaking head gasket. To check for the third go to Auto Zone and get them to do a compression check, its free. I can't remember off hand but if the 93 has a TPS (throttle position sensor) that could also cause an irratic idle.

SOURCE: Ford Escort 1998 fuel pump not working.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

SOURCE: throttle body injectors not fiering but there is fuel pressure

the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up

SOURCE: 1989 GMC 2500 5.7L - engine surges and stalls at idle. Loses power at cruising speed.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

What is next on trouble shooting fuel injectors?


what engine?

Do you have power to the injectors? if not check the ECM1 fuse. If blown check the wiring harness around the throttle body for pinched wires to the injectors. Really common on the early throttle body engines.

Why wont the fuel go to the carburetor on 1989 chevy 350 cdi. It has new injectors, fuel pump, and fuel filter.


The injectors are mounted in a throttle body.
If you have normal fuel pressure at the injectors, they may not be getting power and ground from the engine computer.

Still having problems will not run good. 1997 ford 2.0 escort;new plugs&wires coil;fuel pump still codes 0351;


From a reputable repair website:


P0351 - OBD-II Trouble Code

Auto Systems and Repair

Ignition Coil "A" Circuit Primary/Secondary Malfunction Our emissions expert has put together the following information about the P0351 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0351 Ignition Coil "A" Circuit Primary/Secondary Malfunction
What does this mean? The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire.
Code P0351 indicates there's an electrical problem in either the primary ( the computer side ) or the secondary ( the spark plug side ) of the Ignition Coil "A" Circuit.
Symptoms
  • Check Engine Light will illuminate
  • Engine idles rough
  • Engine misfires on acceleration
  • In rare cases, the engine may not exhibit noticeable symptoms
Common Problems That Trigger the P0351 Code
  • Defective Ignition Coil(s)
  • Defective Spark Plug(s)
  • Intake Manifold Vacuum leaks
  • Carbon buildup in the Throttle Body air passages
  • Defective Idle Air Control Valve or Electronic Body
Common Misdiagnosis
  • Ignition coil(s) replaced when cause of the malfunction was a vacuum leak
  • Spark Plugs replaced when cause of the malfunction was a vacuum leak

1989 ford stalls when idling ,runs rough at idle


Check for any trouble codes in the engine computer, and have the fuel pressure tested. If it is throttle body injection. observe the spray pattern of the injector when it pulses. You should see a cone pattern of the fuel spraying down into the intake. If it drips, or appears anemic, the injector might be partially clogged. Try some injector cleaner in the gas tank.

There is many thing that could go wrong. I will list some for you to try to pinpoint the problem with out paying the mechanic to do.
1. Cloged fuel filter and possible inpurities in fuel system
2. Faulty or incorecctly gaped spark plugs
3 Fault in the fuel or electrical system
4. incorect ignition timming
5. Defective spark plug wires
6. Low or uneven cylinder compression pressures. Perfom a compression test.
7. Weak or faulty ignition system.
8. Vacuum leaks in the intake manifold or vacuum hoses.

Sounds like you may need to have your injectors cleaned. Old fuel is hard on the small tolerance injectors. Also, check and clean the throttle body butterfly valve to ensure it operated freely.

Ford escort 1989 increases its speed without stepping on the gas


First guess is that a motor mount is broken and lifts one side of the motor just enough to pull on the throttle cable.
Second guess is that the cable return spring is broken or missing. It pulls the injector throttle body lever closed when the gas peddle is released.

Wont start


Make sure that you're getting spark. A very common thing on these engines are coils going bad. If you can verify spark, check to make sure you have an injector pulse. As you rotate the engine, look inside of the throttle body and make sure that you see fuel pulsing into the engine. You can still have good pressure but you don't have an injector pulse, the fuel still cant get into the engine. You can use a test light as well to test for an injector pulse. One wire going to the injector will have constant power and the other will blink when the engie is rolled over. Does it start if you spray starting fluid into the throttle body? If it does, it's a fuel delivery problem. Again be sure you have spark from coil to distributor and plugs. You can remove the ignition module and take it to NAPA and they have a module tester. Have them test the module several times not just once. This will eliminate the possibilites of an intermitted problem. Let me know how it does. tiqautoperformance@live.com
