I had a similar problem with my 1999 E150 Van. After changing plugs and wires didn't solve the problem, my service technician said it was a problem with the automatic transmission. That was hooey! (technical term :-) In my case, the service engine light came on. I don't remember the exact codes, but they pointed me to 2 problems. 1) Misfire on #4. 2) O2 sensor error.

I researched the O2 sensor problem and found out that it was probably caused by a dirty Max Air Flow (MAF) sensor. On my van, the sensor is accessible by taking out the air filter. It's a very fine wire just beyond the filter. Spraying the MAF sensor with some electrical contact cleaner solved the bucking problem. (CRC brand electrical contact cleaner available at Wal-Mart for about 3 bucks)

Hope this helps.

I would check the timing on this bad boy as it sounds to be off by a few degrees.

Check the choke in the carb, might stay stuck in the open position when engine cools down. After the engine is cold, check and see if the choke is closed, if not close it by hand, and see if that works.

SOURCE: 89 ford probe, 2.2 turbo, no spark.

Check out your "fuel cut-off switch" located by the windshield washer tank behind the driver's side wheel-well panel in the trunk. It's a small box with a push-button at the top. If the button is "soft" when you push it, that's probably your problem. Replace the unit by removing the washer fluid tank first. The box simply plugs in. Probably about $ 100. I replaced three in my Probe. They rot out, and the car simple dies.

My ford ranchero doesnt start no power goes to distributor new spark plugs, and i tested the coil what could be the problem?


What is model year? I may not be able to find much info on this vehicle.
The basics, did you check for primary voltage to the coil+, usually goes with the key on. If you use a test lite on negative side of coil the lite should pulse, engine cranking. Is this a points ignition? Have your tried new points. The dist cap--rotor--coil wire all good? Does the rotor turn when you crank it?

Will not start. fuel pressure is good. I changed the ing control module and the coil, new dist cap and rotor. new plugs.


Instead of just bolting on parts, run tests. Do you have spark at the plugs? If not, could be crank sensor. Do you have compression?

Were any of those parts faulty ? Did you test any of them first ?
Since you have replaced the ignition system the next phase would be fuel injectors and mechanical parts.
Have you run a compression test yet ?

I have a 95 chevy blazer with the 4.3 .i have tested and have spark entering the distributor but no spark leaving the distributor to plugs .have put new crank sensor ,cam pos sensor...


That is indeed odd. I would suspect problems with the hi tension cables if this was not part of the ones you changed since the flow of current ends at the distributor. Check also other cables such as the ground. It is puzzling that all plugs would not have any spark. I would also recommend a scanner used to check for error codes given out by the car's ECU.

No spark, 1988 Toyota Camry 3SFE 4cyl, 5 speed.


there is no crank sensor on this vehicles 2.0L. If you have power to the coil, new coil, cap and rotor try this if not done yet>>>Unplug coil power first....Try pulling off the distributor cap, and make sure the rotor is spinning with the cam...If this fails to spin, inspect the entire distributor assembly. If it passes, Inspect all the power circuit and wiring to the dist assembly, if ok possible ecu. i recommend having a mechanic check it out!! Hopefully this helps...please rate...thanks

We replaced the crank sensor and cam sensor on a new 5.2 engine in a 1998 Dodge Durango. We checked and rechecked the connections and still no spark.


check the wiring harness at the coil,sometimes that plug will get loose or dirty resulting in a no spark.
The only ign system parts are the crank sensor,cam sensor,dist,dist cap,rotor,spark plugs,wires,and coil,and the ecm which controls all of these,is there a check engine light on?
run a scan tool to check for stored codes or system events stored in the ecm.
