Code 17 & 18 are crank/cam correlation codes. Depending on what car you have, some sensors are dual sensor, crank and cam in one. Some are set up with up to three sensors. One crank and one or two cam sensors. I you have a dual sensor, I would replace it, but check the plug first. Sometimes corrosion can mess with sensors. Just unplug it and plug it back in. This usually takes care of contact issues. Clear the light and see if that code comes up again. If you have two or more sensors, then we are talking timing belt issues. To check code 26, you will have to check for voltage on that wire. Pinout and color codes are needed to find the wire from the ECM. Again not knowing your car, voltage could be 5,8, or 12 volts. Or real close to these numbers. If you don't see any voltage from here, the ECM is bad. Quad drivers either work or don't work. 56 is an 02 heater code. This could make the car run a little rough, but not cut out. Now the injector test, if you didn't get a reading from the injector, it is bad. This will make the run real bad, Because you lost that cylinder.

SOURCE: my 2002 nissan sentra will crank but won't start. i've replace the ecm/ecu, the cam/crank sensor or position, checked the fuel pump/pressure, and it still is doing the same thing. sometimes it

I assume you checked the fuel pressure and it is normal.
Are the spark plugs getting spark when it fails to start ?
Are you getting injector pulse from the computer ?
Any trouble codes stored in the computer ?

SOURCE: So... I'm starting to get just a bit frustrated... after installing the new PCM, my dodge avenger, 96 2.0L ran for 5 days then went out again, fuel pump works and I've got spark but no start..

after all that work its terrible that something else goes bad however since you do get spark and fuel i would say crank or cam sensor but then if one of those goes bad it wont allow engine to turn over and would shut fuel pump off. so there is only one thing left to cause it you have a short in the harness somewhere maybe just a lose connection on the cam or crank sensor put dieelectric grease in all your connectors

2004 gmc sonoma why does it take 2-3 times cranking before it starts and only does it sometimes?


install pressure gauge and watch when key is turned off to see if pressure drops to zero if so bad drain back valve in fuel pump replace it or deal with it or could be cheap aftermarket pump and has hard time building unnecessary pressure to open poppet valves between before fuel injectors

I found my problem to be the ht pack.After washing and driving on very wet roads,once the ht pack dried out it worked fine again. Remove the ht pack and close the plug connection and give it a good coating of plasticote70 from crc. this should be available at most electronic suppliers.

95 mustang, driving along and car just dies. wait 30 min s0metimes it will start and sometimes it wont. no spark. why?


Ignition modules and pick-up coils are pretty common on the older fords. When it doesn't start check for pulse at the coil. You can do this with a test light. Hook the lead wire of the test light to ground. Unplug the coil, turn the key on and see which of the two wires has power to it. Then plug the coil back in and back probe the wire that did not have power and crank the engine over. The test light should flash. If it does not than I old suspect the ignition module and would probably replace the pickup cl in the distributor for good measure. This was a fairly common symptom back in the day.

I have a 1995 saturn sl and it just started idleing up to 3 0r 4 rpm's when i start it and sometimes cuts off going dwn the rd service engine light comes on.this morning the same thang but it now feels...


Sounds Like the Common Item on these Saturns, and that is ( (COIL PACK) you Probably have the Missfire on Matching Cylinder BANK . You DO NEED to Check For Codes to ZERO in on it I think you will see a CODE po161 - 166 < I Believe these are the Codes that set for MISSFIRE .
