It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

have the EGR valve tested because this will cause the engine light to come on and also check all vacuum lines

Why won't 89 Chevy Silverado 1500 5.7 STILL not start. New battery,coil,spark plugs,wires,inline filter,distributor,cap,rotor,fuel pump,starter relay.


What's missing ? Fuel ,spark , compression ? How many miles on the vehicle ? Does it have spark , pull a plug wire while cranking an hold it near a good ground . Put a fuel pressure gauge on the vehicle , is there fuel pressure ? Do a compression test , 150 psi . engine mechanical problem . timing chain .

89 ford F 150 . Lost fire to fuel pump and spark to plugs at the same time


There is a bad connection . Could be a loose fuse. loose wire , faulty circuit breaker . or ignition switch. If the fault is still there start at the ignition switch hot wire should be 12 volts, turn on ignition should be 12 volts on + terminal of ignition coil and 12 volts at fuel pump. if not repair as required .

I've tested my coil by simply placing a spark plug at the end of the plug wire and ground it to the engines ground and by turning the key I looked for a bright blue spark to see a amber spark instead


well if it starts with starter fluid then you need to change the fuel pump and fuel filter, if it had anything to do with spark it would not start with starter fluid.

do you have spark or fuel you can check for fuel by pushing a small flat head screwdiver into the shrater vavle located on the fuel rail it looks like a vavle stem with a black cap
to check for spark take a park plug wire off a spark plug and put a new spark plug in it set it on the motor some were and have a friend turn the car over if it has spark it will be a bluish yellow color
good luck

Changed fuel pump. getting fuel to engine. but will not start.


Check for spark. Maybe a crankshaft position sensor is bad or a module.

Secondary Spark Test This spark tester looks just like a spark plug, attach the clip to ground and crank the engine to check for spark 91052p10.jpg
This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems 91052p11.jpg
Attach the clip to ground and crank the engine to check for spark 91052p12.jpg
This spark tester is the easiest to use just place it on a plug wire and the spark voltage is detected and the bulb on the top will flash with each pulse 91052p10.jpg
The best way to perform this procedure is to use a spark tester (available at most automotive parts stores). Three types of spark testers are commonly available. The Neon Bulb type is connected to the spark plug wire and flashes with each ignition pulse. The Air Gap type must be adjusted to the individual spark plug gap specified for the engine. The last type of spark plug tester looks like a spark plug with a grounding clip on the side, but there is no side electrode for the spark to jump to. The last two types of testers allows the user to not only detect the presence of spark, but also the intensity (orange/yellow is weak, blue is strong).
  1. Disconnect a spark plug wire at the spark plug end.
  2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine.
  3. Crank the engine and check for spark at the tester.
  4. If spark exists at the tester, the ignition system is functioning properly.
  5. If spark does not exist at the spark plug wire, perform diagnosis of the ignition system using individual component diagnosis procedures.

Ignition Coil Testing
  1. Remove suspect coil.
  2. Disable fuel pump by disconnecting inertia switch electrical connector.
  3. Reconnect the ignition coil electrical connector to the coil.
  4. Install spark tester 303-D307 (D81P-6666-A) or the equivalent.
  5. Crank engine while observing the tester.
  6. If a blue-white spark is not observed replace coil.

Removal & Installation To Remove:
  1. Remove the air cleaner outlet pipe if interfering.
  2. Disconnect the connector from the ignition coil. coilconn.gif

  3. Remove the bolt from the ignition coil. coilbolt.gif

  4. Remove the ignition coil on plug.
To Install:
  1. Install ignition coil on spark plug.
  2. Install ignition coil bolt. Tighten to 10 Nm (89 in. lbs.). coilbolt.gif

  3. Reconnect the ignition coil electrical connector. coilbolt.gif

  4. Install the air cleaner outlet pipe if removed earlier.

Check and see if u have spark to the plugs, if you don't replace the TFI ignition module on the distributor and the pickup inside the distributor, the dist must be removed to do this coil pickup replacement.
Comment posted on Mar 04, 2009 also check the fuel pressure if the spark is ok, the ignition is the ,most common issue. Comment posted on Mar 04, 2009 also check the fuel pressure if the spark is ok, the ignition is the ,most common issue.
