Question about 1999 Chevrolet S-10 Pickup

1 Answer

99' S-10 with no spark

It cranks, but will not start. There is no spark going to the plugs. I have replaced the plugs, the wires, the crank sensor, and the coil. I had the module tested and it is good. The check engine light recently came on about a week before. The first few times I tried starting it, it didn't sound like the fuel pump was kicking in. I droped the tank and tested the fuel pump and after I put it back together it kicks in fine when the key is turned. I have cleaned a couple of the sensors I know about and have tried to reset the check engine soon light by disconnecting the battery for several minutes and reconnecting it. I have 2.2L 4 cyl engine, going on around 162k miles an any help would be appreciated.

More than likely the cranck sensor went bad. Its a magnetic pickup bolted on the engine block facing at the crackshaft area in the mid way part of the block. If bad no spark will ocuur

    The PCM needs to be checked although that has to be done at a shop or a dealership

2006 nissan x terra. spins over, wont start. replaced fuel pump assembly, crank sensor, left side cam sensor. not getting any cranking rpm from scanner. HELP !


This already sounds all kinds of bad.
Lets start with spark. Did you verify it can make 30kv at all plugs while cranking? f you havent...start there. Do you have any codes in any modules? Engine, theft, trans, body?
Do you have vacuum cranking, do you have MAF reading cranking? do we know if its mechanically still in time? Did you do a cranking compression test? If you have spark, and you remove the fuel pump relay...does it start when it isnt flooding? What is your system and reference voltage...what is cranking vacuum? And what tests did you run that inspired changing all that stuff? Check the c ranking rpm in Generic mode just rpm onscreen, some OEM software doesnt update well during cranking, with one pid selected, solus should update better than 10x a sec, If you still have no signal...you need to measure the crank sensor wires or verify the crank sensor ring is even turning,

Car cranks but will not start


This could go several ways #1 engine mechanical check cranking compression should have 125 psi or greater in all cylinders if low but even squirt oil (1/2 oz.) in 1 cylinder and retest goes higher then rings sealing has been lost. if uneven check timing belt for jumped or misalignment. #2 electrical does it have electrical spark to plugs crank engine with a spark plug connected to spark plug wire laying plug on engine can you see spark? No test ignition coil wires with a logic probe both terminals will be red with key on one will flash red/green when engine cranking does not the primary ignition needs repair Ignition module? or pick-up coil/ crank sensor. #3 fuel system pressure and injection pulse. injection pulse can be tested with logic probe DONOT USE A TEST LIGHT YOU CAN RUIN THE ECU .

With that much already invested, why give up now? How about the crank position sensor-was that replaced as well? For spark control and spark timing, the computer needs inputs from both the cam position sensor and the crank position sensor before it can know when to cut power to the coils for spark to occur.
Before proceeding any further, you should check for diagnostic trouble codes. You would need an OBD 1 type code reader or scanner for your olds. Any stored codes may help you find the problem.
You can test the ignition system by checking for spark on a spark plug wire when the engine is cranking over. Pull the plug wire off a spark plug and put in a clean spark plug into the wire. Lay the plug so the threads are touching metal on the engine somewhere. Have someone crank the engine over and watch for a spark from the spark plug. If you have a blue, snapping spark when cranking, ignition is good.
One last note: since it dies when driving, there is a possibility that you have a malfunction in the pcm-the computer.

The fuel pump pressure shoud be 55-61 psi . Check for spark by removing a ignition wire at a spark plug and put a spark plug in wire and hold to engine ground and crank engine , if no spark then remove coil wire at cap and repeat.If still no spark then coil , module,,crank sensor or pickup may be the problem.
Check fuel pump pressure first and if available check for codes for possible crank sensor.

Crank sensor is primarily for the spark and the cam sensor is for fuel management, crank/cam correlation for misfire purposes I would also change the wires.

If you have good fuel pressure. Check for spark at any plug while cranking, If no spark, also place a screw driver on an injector and listen to it while someone cranks it over. If you have NO spark and NO injector click - crank sensor needs to be replaced. 95%
other 5% hmmm wiring problem on / near crank or cam sensors, theft system active, dead pcm.......

1992 Ford Taurus wagon not starting, but turns over


You might have a problem with your crank sensor or ignition. Remove spark plug wire and check for spark while turning engine over. When this happens unplug crank sensor near crank pulley then plug back in to see if it starts if so replace crank sensor.
